CYPECAD. Integrated 3D structures

Copy integrated 3D structures

  • Option description
    This new option allows users to create a new integrated 3D structure in the current group based on one which has previously been introduced in another group. The option is located within the Job menu: Job> Integrated 3D structures > Copy structure.
  • Help available to explain how to use the option
    As well as the help available within the dialogue box where this option appears, when the user selects it, the program displays the steps that are to be followed in the bottom part of the screen (below the Column Definition tab, Beam Definition tab….).

Rotate integrated 3D structures

  • Option description
    This new option allows users to rotate an integrated 3D structure. The option is located within the Job menu: Job> Integrated 3D structures > Rotate structure.
  • How to use the option
    An integrated 3D structure can be rotated in two ways:
    • By indicating the numerical value of the angle
      • Select the integrated 3D structure to rotate
      • Select the rotation point
      • Select the rotation angle
    • Graphically using reference points
      • Select the integrated 3D structure to rotate
      • Select the rotation point
      • Select a reference point
      • Select any point of the straight line joining the rotation point with the future position of the selected reference point.
    The rotation point and reference point do not have to be points of the structure.
  • Help on how to use the option
    The program has the following help options to aid users:
    • Help icon icon of the dialogue box
      Help available in the dialogue box where this option is located.
    • Step by step guide
      When the user selects the option, the program displays the steps that are to be followed in the bottom part of the screen (below the Column Definition tab, Beam Definition tab….) so the operation is carried out correctly.
    • Provisional view of the new position of the structure
      The program provides a provisional display of the integrated 3D structure as the mouse cursor is moved after the reference point has been selected and before selecting its future position.
  • Rotation of the horizontal loads
    If horizontal loads are present, such as wind loads, the program analyses and manages the rotation of these loads together with the rotation of the integrated 3D structure. The program will ask the user to confirm different actions, depending on whether the structure has or has not got any loads included in a loadcase used by other integrated 3D structures or in the job in CYPECAD:
    • The horizontal loads of the integrated 3D structure to be rotated act in a loadcase not used by other integrated 3D structures or by the job in CYPECAD
      In this case, the program asks the user to define how these loadcase combine with one another and with other horizontal load loadcases of the same type (wind, for example) that may exist in the structure of CYPECAD or in other integrated 3D structures. The program’s default option is set so these loadcases are analysed as independent loadcases, i.e. they do not act simultaneously with the others.
    • The horizontal loads of the integrated 3D structure to be rotated act in a loadcase are also used by other integrated 3D structures or by the job in CYPECAD
      The program asks the user to choose between the following:
      • Keep the horizontal loads of the integrated 3D structure to be rotated in their current loadcase and check whether they are valid later on.
      • Apply the horizontal loads of the integrated 3D structure to be rotated in new loadcase combinations created automatically by the program.
      In either case, the program then displays a dialogue box where the loadcases can be combined, similar to when the loads of an integrated 3D structure to be rotated belong to a loadcase not used by other integrated 3D structures or by the job in CYPECAD.

Align integrated 3D structures

  • Option description
    This new option allows users to align an integrated 3D structure. The aligning of a structure consists of a displacement and a rotation. The option is located within the Job menu: Job> Integrated 3D structures > Align structure.
  • How to use the option
    An integrated 3D structure can be aligned by selecting two reference points and indicating its new position. The reference points do not necessarily have to be points of the structure. The procedure is as follows:
    • Select the integrated 3D structure to align
    • Select the first reference point
    • Select the new position of the first reference point
    • Select the second reference point
    • Select any point of the straight line which will join the new positions of the reference points.
  • Help on how to use the option
    The program has the following help options to aid users:
    • Help icon icon of the dialogue box
      Help available in the dialogue box where this option is located.
    • Step by step guide
      When the user selects the option, the program displays the steps that are to be followed in the bottom part of the screen (below the Column Definition tab, Beam Definition tab….) so the operation is carried out correctly.
    • Provisional view of the new position of the structure
      The program provides a provisional display of the integrated 3D structure as the mouse cursor is moved after the reference point has been selected and before selecting its future position.
  • Rotation of the horizontal loads
    If horizontal loads are present, such as wind loads, the program analyses and manages the rotation of these loads together with the rotation of the integrated 3D structure. The program will ask the user to confirm different actions, depending on whether the structure has or has not got any loads included in a loadcase used by other integrated 3D structures or in the job in CYPECAD:
    • The horizontal loads of the integrated 3D structure to be rotated act in a loadcase not used by other integrated 3D structures or by the job in CYPECAD
      In this case, the program asks the user to define how these loadcase combine with one another and with other horizontal load loadcases of the same type (wind, for example) that may exist in the structure of CYPECAD or in other integrated 3D structures. The program’s default option is set so these loadcases are analysed as independent loadcases, i.e. they do not act simultaneously with the others.
    • The horizontal loads of the integrated 3D structure to be rotated act in a loadcase are also used by other integrated 3D structures or by the job in CYPECAD
      The program asks the user to choose between the following:
      • Keep the horizontal loads of the integrated 3D structure to be rotated in their current loadcase and check whether they are valid later on.
      • Apply the horizontal loads of the integrated 3D structure to be rotated in new loadcase combinations created automatically by the program.
      In either case, the program then displays a dialogue box where the loadcases can be combined, similar to when the loads of an integrated 3D structure to be rotated belong to a loadcase not used by other integrated 3D structures or by the job in CYPECAD.

Metal 3D and Integrated 3D structures of CYPECAD

  • Rectangular concrete section with variable depth
    The user can now introduce rectangular concrete bars with variable depth in Metal 3D and Integrated 3D structures of CYPECAD. These have been added to the circular and rectangular concrete sections of constant depth which can be introduced as of previous versions.

CYPECAD and Metal 3D

Joints III. Welded. Building frames

  • In previous versions, in the case of joints consisting of two or more beams fixed to a column (one to the web and the other to a flange), if the beam with greatest depth is fixed to the flange of the column, the stiffeners of the flanges of this beam interrupted the plate coplanar to the web of the beam fixed to the web of the column. The connections were designed correctly. Nonetheless, as of the 2010.k version, the program designs the connection and extends the plate which is coplanar to the web of the beam fixed to the web of the column so it covers all the space that lied between the flanges of the beam. In order for this to be possible, the stiffeners corresponding to the flanges of the beams fixed to the flanges of the column are divided. This way a connection with greater stiffness is designed and more connections with different beam depths can be resolved.

Export to Tekla Structures

  • The module Export to Tekla (common to CYPECAD and Metal 3D) allows for the structure to be exported to Tekla 14.1

Metal 3D. Aluminium sections

Joints II. Bolted (CYPECAD and Metal 3D)

  • New types of bolted connections
    New types of bolted connections have been implemented in the Joints II: Bolted module. The following types have been added to the existing types of bolted joints:
    • Column transition
      At column to beam connections, which could be resolved in previous versions when the column was continuous or at its last span, these can now be resolved with the condition of it being at a column transition.
    • Intermediate stiffener corresponding to the bottom flange of beam moment connections with haunch
      All bolted connections consisting of a one or two beam to column flange moment connections with a haunch are designed in such a way that an intermediate stiffener for the bottom flange is not required. The absence of this stiffener avoids problems that may arise when placing beams pinned to the column web and allows for a reinforcement plate to be placed at the column web if necessary.
    • Bolted column to two beam moment connections
      The two beam to column flange moment connections can consist of I sections, with different slopes and levels. Additionally, the program allows for one of the beams to have a haunch when the other does not.

Joints (CYPECAD and Metal 3D)

Improvements in the Joints I. Welded. Warehouses with rolled and welded steel I sections module

  • Intermediate stiffener corresponding to the bottom flange of fixed beams with haunches.
    All welded connections consisting of one or two beams with haunches fixed to the flanges of the column are designed in such a way that the intermediate stiffener corresponding to the bottom flange is not required. The absence of this stiffener avoids problems when trying to connect beams to the web of the column.

    These stiffeners were suppressed for some cases in the 2010.e version.
  • Two beam to column flange fixed welded connection
    The program allows, for all types of welded connections consisting of two lintels fixed to the column flanges which have been designed using the Joints I module (with one or two beams pinned to the web of the columns, at the end of the column, at a column transition, with a continuous column, with or without haunches…) for the lintels to be of different sections, with different slopes and any level, with the added option that only one haunch may be present.
  • One or two beam to column web pinned welded connection
    The one or two beam to column web pinned welded connection has been implemented when this occurs at column transitions. When there are two pinned lintels, they may be of different sections and slopes (at column ends, at column transition or at continuous column).
  • Beam to column flange pinned welded connection at column transition
    A beam to column flange pinned welded connection has been implemented when this occurs at column transitions.
  • Joining of elements with differing sections
    Elements of differing sections may be joined together by means of a welded connection as long as the flanges of one of the elements remain contained within the flanges of the other. A haunch may be provided at the connection.

Improvements in the Joints III. Welded. Building frames with rolled and welded steel I sections module

  • Implemented welded connection: beam to column web fixed welded connection (at column transition), and with two orthogonally pinned beams.
  • Column flange to two lintel fixed connections with one or two orthogonally pinned beams to the column web
    Implemented welded connections: Column flange to two lintel fixed connections with one or two orthogonally pinned beams to the column web (at column ends, at column transition and at continuous column). Lintels can be of differing sections and at any level, regardless of whether there are beams pinned to the web of the column.
  • Joining of elements with differing sections
    Elements of differing sections may be joined together by means of a welded connection as long as the flanges of one of the elements remain contained within the flanges of the other.

General improvements in the Joints modules (Joints I, II and III)

  • View uniformity and detail sections of similar joints
    The criteria to obtain the views and sections of the details of similar joints are unified.
  • Message information when unable to design
    The messages as to why a connection or design has not been dimensioned have been improved.

Improvements for all programs

DWG files generated by AutoCAD 2010

As of the 2010.g version of the program, all CYPE programs can read files in DWG format which have been generated by AutoCAD 2010.

Publish jobs on internet

  • A new option has been implemented for all CYPE programs in which the user can share a job compressed in ‘CYP’ format (CYPE’s own format) on internet. The job will be published on a server and will be accessible to third parties via a private link. Therefore, only those who know the correct link will have access to the job.

    To use this option, simply select a job form the File manager dialogue box (File > File manager) in any CYPE program and click on the Share button. The user can include a title and a comment in the job to be shared. Another dialogue box will then appear which indicated the link where the job is located, which may be copied by selecting it using the left mouse button so it may be provided to the person he/she wishes to see it. This dialogue box also opens the webpage where the job has been published.

      The file links.txt, which is generated in the directory usr/cype/cypecad contains the links of all the jobs that have been published. This file also contains the links of the screen images that have been captured and published using the option described in the section below.

Capture images to share on internet

  • Any CYPE program screen can be captured to then share on internet via a private link which the user can then provide to or publish wherever he/she wishes to. Only those who know this link will have access to the captured image.

    The image capture option is activated by pressing the F12 button of the keyboard whilst the active window on screen is that of a CYPE program. A dialogue box will then appear displaying the captured screen image and where the user can assign it a name and add a comment. Within this dialogue box, the user has the option to select only part of the captured image for it to be published. To do so, select the area of the image by opening a selection window over the image using the left mouse button.

    Having accepted the dialogue box, the program offers the user in a different window, two types of URL addresses so the user may insert the captures in any forum. The selected address will depend on which forum the URL is to be published at. Within the same window, the link which allows access to the published screen from any internet connection is provided.

    The file links.txt, which is generated in the directory usr/cype/cypecad contains the links of all the published screen images. This file also contains the links of the jobs that have been published using the option described in the section Publish jobs on internet. 

Search for jobs

To help in locating jobs, a new search option has been implemented within the File manager dialogue box (File > File manager). Upon clicking on the Search button, the Search for job using thesaurus dialogue box appears. This options allows the user to search for jobs in the directory selected in the previous dialogue box (File manager) which contain the word indicated by the user in their name or description.

The lintels can have different depths, different slopes, their flanges do not have to be level, one can also have a haunch whilst the other does not.
  • Beam connections
    • Welded ridge joints using an end plate for beams possessing different depths even if unlevelled and without the flanges having to coincide (as long as the flanges of one of the beams are contained within those of the other). The beams may be inclined differently (in previous versions, the slope difference had to be small).
    • Welded joints consisting of a horizontal beam connecting to an ascending or descending beam. The beams may have different depths, do not have to be levelled and their flanges do not have to coincide ( as long as the flanges of one of the beams are contained within those of the other).

Improvements in the Joints I module (warehouses)

  • The lintel arrangements at column transition points indicated in the previous section (lintels with different depths and /or inclination, one with a haunch and the other without, without the need of the flanges having to be at the same level…) are also valid for joints with a continuous column or at the end of a column. These joints already existed in previous versions and now their properties have been improved so to have the same advantages as joints at column transitions.

New welded joints for the Joints III module (building frames)

  • Some joints belonging to the Joints I module (Welded. Warehouses with rolled and welded steel I sections) have been added to those available with the Joints III module (Welded. Building frames with rolled and welded steel I sections) with some arrangement restrictions (beams cannot have haunches and have to be horizontal, except at the end of a column). This way, pinned joints in a building structure can be designed only using the Joints III module. The following types of joints have been added:
    • Joints at column transitions
      • Welded joints consisting of a lintel fixed to a column flange (without haunch and with horizontal beams), with one or no orthogonal pinned beams.
      • Welded joints consisting of two lintels fixed to a column’s flanges (without haunches and with horizontal beams), without orthogonal pinned beams. The lintels can have different depths and their flanges do not have to have to be at the same level.
    • Joints at continuous column connections
      The Joints III module only resolves nodes with continuous column connections in the Integrated 3D structures of CYPECAD or in Metal 3D.
      • Welded joints consisting of a lintel fixed to a column flange (without haunch and with horizontal beams), without pinned beams orthogonal to the web.
      • Welded joints consisting of two lintels fixed to a column’s flanges (without haunch, and with horizontal beams), without orthogonal pinned beams.
    • Joints at column ends
      • Welded joints consisting of a lintel fixed to a column flange (without haunch and with beams at any angle with respect to the horizontal plane), with one, two or no orthogonal pinned beams.
      • Welded joints consisting of two lintels fixed to a column’s flanges (without a haunch and with horizontal beams), without orthogonal pinned beams.

Other improvements in the Joints modules

  • Intermediate stiffener corresponding to the bottom flange of fixed beams with haunches (Joints I module)
    The intermediate stiffener corresponding to the bottom flange has been removed for welded joints consisting of one or two beams with haunches fixed to a column’s flanges (Joints I module – welded joints for warehouses) in the following cases:
    • Joints consisting of a beam fixed to a column flange with one or no orthogonal beams pinned to the column web
    • Joints consisting of two lintels fixed to a column’s flanges without beams pinned to the column web.

    These joints are designed in such a way that the intermediate stiffener that has been removed is not required. The absence of this stiffener avoids problems which arise when pinning the beams to the column web.

    This stiffener will gradually be removed from more joints in future updates.

  • 3D views of joints resolved by non-acquired modules
    Even though the user license does not contain the joints modules, the program allows the user to activate the joints design. After this procedure, 3D views of the joints that could be resolved with the non-acquired modules can be seen. Details, reports and take-offs of these joints are not displayed. When the cursor is placed over one of these nodes, a warning appears displaying the non-acquired modules that have been used to design the joint.
  • Joint design options using the Brazilian code: ANBT NBR 8800:2008
    The design options for welded joints can be configured when the Brazilian code (ANBT NBR 8800:2008) has been selected (in CYPECAD and Metal 3D: Joints > Options and in CYPECAD: Job > Joint analysis options).
  •  Identification of joints modules acquired in the user license
    A list is displayed in the Analysis dialogue box (appears when a structure or joints are being analysed) which shows the joints modules which are implemented. Each of them has a mark on their left that indicates which are included and which are not in the user license being used to carry out the analysis.

CYPECAD

New type of panel. Panels awaiting definition

  • A new type of panel has been included in the program: Awaiting definition.

Introduction method and properties of panels awaiting definition

  • When a structural perimeter is defined by means of beams or walls, the program automatically assigns a panel awaiting definition to the inside of this perimeter.
  • Using the option Awaiting definition from the Panel manager dialogue box (Slabs > Panel manager > Define panel) any opening or previously defined panel can be changed to one awaiting definition.
  • Panels awaiting definition can be substituted by openings (Slabs > Panel manager > Delete panel) or by any other type of  panel available in CYPECAD (Slabs > Panel manager > Define panel).
  • A panel awaiting definition can be assigned an elevation change, a slope and a depth. If the depth is assigned, any flat beams around its perimeter will adopt this depth.
  • Jobs containing panels awaiting definition cannot be analysed.

Benefits of using panels awaiting definition

  • There is less probability of the user forgetting to define a panel before the analysis, as it is not possible to analyse a job containing this type of panel. The program automatically introduces this panel when a structural outline (by means of beams or walls) is created.
  • The depths of  any flat beams surrounding this panel adopt the depth of this panel if it has been previously defined or if the structure has been imported from an IFC file. In these cases, the program does not inquire if a depth is to be assigned to each flat beam when changing groups or when saving the job before the final type of panel has been defined.
  • The panel awaiting definition is displayed in the 3D views. This allows the user to have a 3D view in which openings and slabs can be seen before the final type of panel has been introduced.
  • Importing of IFC files is improved. These improvements can be seen in the Automatic job introduction. CAD/BIM models section.

Automatic job introduction. CAD/BIM models

  • Improvements when importing IFC format files
    In this version, CYPECAD imports the slabs contained in the IFC files as slabs awaiting definition (new type of panel of the 2010.e version). These are imported with their corresponding elevation changes and slopes and CYPECAD assigns them a structural depth deduced from the data contained within the IFC file. More information on the properties of the new type of panel of CYPECAD can be found in New type of panel. Panels awaiting definition.

    In previous versions only slab outlines were imported and all appeared as openings. Using the current import, the user can distinguish between real openings and floor slabs.

    CYPECAD does differ between the IFCROOF and IFCSLAB entities. Therefore in the case of roofs, CYPECAD allows for the user to select the types of beam which are to be assigned to outlines and those which are to be assigned to ridge or valley beams.

Job data for timber and extruded aluminium

  • Within the general data dialogue box of CYPECAD (Job > General data, from the Column Definition, Beam Definition or Results tabs) the default properties of concrete and steel can be defined and now it may also be done for timber and extruded aluminium. The data introduced for these two materials only affects timber or aluminium bars which the integrated 3D structures may contain, whether these have been introduced using CYPECAD or Metal 3D. Each timber or aluminium bar of the integrated 3D structures can have properties different to the default properties defined for the job within the General data dialogue box (Bar > Describe material, from an editing window of an integrated 3D structure).

Column baseplates in CYPECAD designed using the Joints modules

  • The baseplates of I section columns introduced in the Column Definition tab of CYPECAD are automatically designed as welded plates when the joints are designed.

Reports

  • Sum of the forces of the columns, shear walls and walls by loadcase and floor
    This may be selected together with the rest of the Forces in columns, shear walls and walls reports (File > Print > Job report > Forces and reinforcement in columns, shear walls and walls).  This report allows the user to know which forces act above the base elevation of the supports of a floor.
  • Improvements in the Forces in columns, shear walls and walls reports
    Their general aspect and presentation has been improved.
  • Column displacement and column distortion reports
    These reports are now displayed for persistent or transitory situations, seismic situations and accidental situations instead of only displaying maximum values.

Other improvements in CYPECAD

  • Joint redesign in CYPECAD
    Once the job and the joints have been analysed, it is possible for only the joints to be reanalysed. This option is useful for cases where, once the job has been analysed, the design option of the joints are to be modified or the user wishes to change to a different type of joint design (welded, bolted with prestressed or ordinary bolts, a different bolt series, etc.). In other words, circumstances which do not affect the calculated forces in the structure or the joints, and therefore the job does not have to be completely reanalysed.
  • Lateral buckling coefficients in sloped steel beams
    Lateral buckling coefficients may be assigned to the top and bottom flanges of sloped steel beams in CYPECAD.
  • Beam axes displayed on screen
    The axes of beams that have been introduced may be displayed on screen, upon activating the Beam axis option within the Show references dialogue box (Groups > Show references).
  • Cracking
    This is similar to what occurs in the case of the U.L.S. for concrete failure. Now, project situations defined by the user can be defined for the U.L.S. for cracking (Job > General data > Limit states (combinations) button > Configure combinations for each limit state button > Concrete or Foundations button > Project situations introduced by the user). Definition of specific project situations is not necessary, as those indicated by the code are included in the program, which does not require for the user to have to pat much attention and so avoid accidently modifying coefficients.

Metal 3D and Integrated 3D structures of CYPECAD

Data introduction assistant

  • When a new job is created in Metal 3D an assistant is displayed which allows the user to introduce the general data of the job:
    • Codes (Concrete for foundations, Rolled and welded steel, Cold formed steel, Timber and Extruded aluminium) and seismic code activation (dynamic spatial analysis).
    • Additional loadcases.
    • Limit states (load combinations).
    • Steel data (rolled or welded and cold formed).
    • Timber data
    • Extruded aluminium data.
    • Foundation data.

The material data defined within the assistant is that which is automatically assigned to each element that is introduced. Using the option Bar > Describe material, a different material to that defined for the job can be assigned to any element.

All the data defined within the assistant can be modified once the process has concluded. This option is located within the Job menu in the Structures tab and by clicking on Job > General data in the Foundations tab. For this reason , the Job menu has been added to the Extruded aluminium sections option so the user may modify the default data that has been defined for the job for that material. 

Concrete and generic bars in Metal 3D

  • As of the 2010.e version, concrete or generic bars can be introduced in Metal 3D. Within the Describe section dialogue box, two new buttons have been added: Concrete bars and Generic section.
    • Concrete bars
      Rectangular and circular bars may be defined. The program calculates the forces which these bars are submitted to and displays the results by simple loadcases, combinations or envelopes. The resistance of concrete bars is not checked, i.e., their sections are not checked or designed.
    • Generic section
      Metal 3D allows for generic bars of any other material to be defined. The program calculates the forces which these bars are submitted to and displays the results by simple loadcases. The resistance of the generic bars is not checked, i.e. their sections are not checked or designed. The user defines the following properties of the bars once they have been positioned:
      • Section geometry. The user introduces the distances between the centre of gravity and the surrounding outline of the section in the two directions of each of the local axes of the section:
        • Left width
        • Right width
        • Bottom depth
        • Top depth
      • Mechanical characteristics
        • Area
        • Shear area Avy
        • Shear area Avz
        • Bending inertia Iyy
        • Bending inertia Izz
        • Torsional inertia It
      • Material
        • Modulus of elasticity
        • Poisson’s ratio
        • Coefficient of thermal expansion
        • Unit weight

Animated deformed shape

  • An animated deformed shape of the structure has been implemented. The option is located within the Force diagrams dialogue box (Analyse > Force diagrams). A button appears to the right of the Deformed shape option which when clicked on causes a new window to open displaying the animated deformation of the structure. It is modelled as a 3D bar diagram and displays the deformed shape due to the selected load combination, indicated in the same dialogue box.

Wind direction coefficient

  • The wind direction coefficient can be defined (Job data > General job data > With wind load option) for the codes indicated below (other codes do not consider this coefficient):
    • Eurocode 1 (General document) - EN 1991-1-4 (2005)
      The user can directly introduce the value of this coefficient for each of the wind directions (0º, 90º, 180º and 270º) in accordance with the adaptations which may exist in the general document of the country in which the building is located.
    • Eurocode 1 (National application document for Belgium) - prNBN EN 1991-1-4 ANB (2009)
      The user defines the angle in the X axis in the positive direction with respect to north. A diagram explaining which is the required angle is available by pressing a button next to the introduction field of this value.
    • Eurocode 1 (National application document for France) - NF EN 1991-1-4/NA (2005)
      The user defines the angle in the X axis in the positive direction with respect to north. A diagram explaining which is the required angle is available by pressing a button next to the introduction field of this value.

      The program automatically selects one of the three zones in which the French territory is divided into when it comes to defining the wind direction coefficient, in accordance with the region indicated by the user in the same dialogue box. Nonetheless, it is possible to select any zone regardless of the indicated region. Next to the zone selection (1, 2 or 3) a button is available which displays a map where the aforementioned zones are defined.

CYPECAD

Check for cracking

  • As well as the check for cracking that can be activated for concrete beams in previous versions, the check for cracking has been added for the following concrete reinforced concrete elements:
    • Sloped beams
      The check for cracking in sloped beams is activated with the same option as for all concrete beams (Job > Beam options > Cracking Code check)
    • Strap and tie beams
      The check for cracking for strap and tie beams is activated in Job > General data > By position button > Foundation tab> Strap and tie beam options button > Code check for cracking
    • Footings
      The check for cracking for pad footings is activated in Job > General data > By position button > Foundation tab > Strip and pad footing options > Code check for cracking

For codes BAEL-91 (R-99), CIRSOC 201-2005 and ACI 318 M-08, it is verified that the tension in the reinforcement does not exceed that stated in the codes. The user classification is taken into account (cracking causing little harm, Harmful or Very harmful). Cracking control in common beams (CYPECAD) is adapted to the criteria of the code.

For the remaining codes, the fissure aperture is calculated, also checking that this value is less than the admissible maximum, which may be edited by the user.

The load combinations are automatically generated in accordance with the concrete code, depending on the data introduced in the Limit states dialogue: Job > General data > Limit states (combinations) button.

Joints

  • Joint consultation
    Joints resolved for the connections with integrated 3D structures can be checked from the Results tab.
  • Baseplates in the connections with integrated 3D structures
    Baseplates in the connections with integrated 3D structures can be designed when these reach concrete columns or beams in CYPECAD (as long as no steel bars reach the node or other steel bars of the integrated 3D structure). Therefore, as of the 2010.b version, the Joints I and Joints II modules resolve, in CYPECAD, the baseplate connections to footings, pile caps, slabs, and concrete columns and beams.

Joints III. Welded - Building frames with rolled and welded steel I sections module

Trimming of stiffeners of beams fixed to column webs

  • The Joints III module designs the connections by optionally trimming the stiffeners reaching column webs. The trimming of the stiffeners can be defined in the joints option configuration dialogue box (In Metal 3D: Joints > Options > Stiffeners tab, and in CYPECAD: Job > Joint analysis options > Stiffeners tab).

    This option does not imply any changes in the structural check only aspects related to the aesthetics of the composition and the number of cutting operations that must be undertaken in its construction phase. Upon activating the option, the trimming of the stiffener is carried out if the following requisites are complied with:
    • The smaller side of the trim must be greater than 10 mm.
    • The angle formed between the inclined side of the trim and the plane perpendicular to the web of the column must be greater than 15º.

Inclined stiffeners of beams fixed to column flanges

  • When the elevation difference between the flanges of the beams fixed to the flanges of a column is small, great difficulty exists to correctly weld a stiffener to each flange. In these cases, the Joints III module can design the connection and offers two possible solutions:
    • A single horizontal stiffener between both flanges
      This is placed when the free distance between the flanges of the beams is less than or equal to the thickness of the stiffener.
    • An inclined flange between both flanges
      This is placed when the free distance between the flanges of the beams is greater than the thickness of the stiffener and smaller than the distance which allows for two stiffeners to be placed (one for each flange). The program does not allow a beam fixed to the web to be supported by an inclined stiffener.

3D views of non-resolved nodes

  • When non-resolved nodes are consulted (Joints > Consult), the Joints III module shows a 3D view of the elements and the connections that have been resolved up to the point at which the error has occurred preventing the completion of the joint design.

Export to Tekla Structures

  • The 15.0 SR1 version of Tekla Structures is added to the existing list of versions of this program to which a structure analysed and designed in CYPECAD or Metal 3D can be exported to.

  • References of the exported elements
    The references of the elements which appear in the Tekla Structures reports are exported from CYPECAD and Metal 3D. This way, these references will be the same in Tekla Structures and in CYPECAD and Metal 3D.

Export to Tekla Structures, TecnoMetal 4D and CIS/2 format

  • Exporting aluminium elements
    Metal 3D and Integrated 3D structures of CYPECAD allow for designed aluminium elements to be exported to Tekla Structures, TecnoMetal 4D and to CIS/2 format
