Building codes

Adaptation to the changes in the CTE (Spanish technical building code)

  • The Ministry of Housing published in the Spanish Official State Bulletin of Thursday, 23rd of April that several Basic Documents of the CTE had undergone modifications. The majority of CYPE programs were adapted to these changes in the 2009.1.k and 2009.1.l versions. In the 2009.1.m version, the adaptation process has been completed by implementing the modifications relative to the DB SI: Safety in case of fire.

Code implementation

  • Code regarding loads on structures. Wind loads
    • Wind Loads according to the National Building Code of Canada (NBC 05) Part 4.1.7
      This wind code has been implemented in the Portal Frame Generator and contemplates a joint analysis of wind loading on all the frames introduced in the job.
  • Code regarding loads on structures. Seismic loads
    • Algerian Seismic Loading Code RPA 99 / VERSION 2003 (Algeria)
      Implemented in CYPECAD and Metal 3D
    • Code for Structural Design in the Republic of Panama (REP-04)
      Implemented in CYPECAD and Metal 3D

Improvements in the application of the code relative to snow loads

  • Code regarding loads on structures. Snow loads
    • RSA (Code for Safety and Loads for Buildings and Bridge Structures) -Portugal-
      The snow accumulation effect has been implemented for this code in the Portal Frame Generator.
    • Eurocode 1 (Portugal) - EN 1991-1-4 (2005)
      In the Portal Frame Generator, the user may select the town were the structure is to be built and the program will automatically assign the corresponding topographic altitude and climate zone.

Metal 3D and Integrated 3D Structures of CYPECAD

Improvements in the ultimate limit state reports of aluminium sections

  • Check for shear buckling
    Within the shear checks carried out by the program, an additional check for shear buckling has been implemented for when the section web is slender.
  • Check for shear and bending
    When the shear effect in the calculation of the design bending moment is negligible, a justification text is generated.
  • Bending checks of elements
    When lateral buckling is negligible, a justification text is generated.
  • Torsion, shear, axial force, and biaxial bending checks of elements
    When the combined effect of torsion and shear is negligible, upon calculating the normal design forces, a justification text is generated.
  • Check for torsion
    The calculation of the plastic torsional modulus has been included in the checks for torsion, so a more precise analysis is carried out.
  • Sections with Iz > Iy
    It is now possible to check sections whose inertia in its Z-axis is greater than that of its Y-axis.

Portal Frame Generator

  • The Canadian wind code has been implemented (as is indicated in the section Code implementation - Code regarding loads on structures -Wind loads)
  • Improvements in the application of the RSA (Portugal) and Eurocode 1 (Portugal) codes, as is indicated in the section Improvements in the application of the code relative to snow loads.

CYPECAD

Detailed reports on ultimate limit state checks carried out on welded and rolled steel sections introduced in Integrated 3D structures in CYPECAD and in Metal 3D.

  • As of the 2009.1.h version, it is possible to obtain detailed reports on ultimate limit state checks carried out on welded and rolled steel sections in Integrated 3D structures in CYPECAD and in Metal 3D

    As of the 2009.1.j version, it is also possible to obtain detailed reports on ultimate limit state checks carried out on welded and rolled steel sections introduced in CYPECAD (columns and beams)

    To view these reports, having analysed the job, click on the following options:
    • Columns
      Results tab > Columns > Edit > select steel column > U.L.S. button

      Or alternatively:
      Column Definition tab > Introduction > Columns, shear walls and starts > Design button > select steel column > U.L.S. button
    • Beams
      Results tab > Beams/Walls > Beam errors > select steel beam > U.L.S. checks button
    • Summarised column and beam reports
      Click on the following option from any tab File> Print > Job report > U.L.S. checks for beams and columns.

Joists

  • Matching of joist top reinforcement and positive moments for all the floor groups of the building
    It is possible to match the top reinforcement of joists and their positive moments on all floor groups without the need of having to change to another group. To do so, the commands Match top reinforcement (Results tab > Joists > [Top reinf.] Match) and Match joists (Results tab > Joists > [Bottom reinf] Match) contain two options: Match in all groups and Match in current group.
  • Joist force diagrams per rib or per metre slab width
    The joist force diagrams can be viewed with their values per rib or per metre slab width. The way in which the results are expressed can be configured for viewing on screen as well as for the joist force reports:
    • On screen
      In the Forces in joists dialogue box (Results tab > Envelopes > Forces in joists) two options have been included: Values per rib and Values per metre width
    • In joist force reports
      In the Force envelopes report (from any tab > File > Print > Job report > Forces in joists > select group(s)) the Values per rib and Values per metre width options can also be activated.

Improvements in the use of the B.A.E.L. 91 code

  • Ultimate limit state combinations for failure
    The Use or Use category and Snow level can be selected so the program may automatically generate the load combinations (in accordance with the selection that has been carried out) for the analysis depending on the ultimate limit states for failure of each material (concrete, foundation concrete, cold formed steel, rolled steel and wood). To do so, new options have been implemented in the Limit states dialogue (Job > General data > Limit states (combinations) button) which allow for the Use and Snow level to be selected for the various materials.

    Additionally, two options have been incorporated in the same dialogue box which generate the combinations of the BAEL 91 code bearing in mind the earthquake code in use:
    • BAEL 91 option
      The load combinations are generated taking into account the PS 92 earthquake code (France)
    • RPS 2000 option
      The load combinations are generated taking into account the RPS 2000 earthquake code (Morocco).

Metal 3D and Integrated 3D structures in CYPECAD

Rotational stiffness calculations for bolted connections

As of the 2009.1.g version, users may introduce a value for the rotational stiffness at the ends of elements using the Fixity at ends option, located in the Bar menu. Metal 3D calculates the initial rotational stiffness of elements fixed to bolted connections which have been designed and displays them in the Joints report so users may compare the value to that introduced.

As of the 2009.1.j version, Metal 3D compares the rotational stiffnesses introduced by the user and those proposed by the program, and displays the comparison in an agile and efficient way using the Rotational stiffness option located in the Joints menu. This option allows the user to automatically assign the rotational stiffnesses proposed by the program as well as review them to decide which rotational stiffnesses to adopt.

CYPECAD

New features in Integrated 3D structures

  • CYPECAD’s Integrated 3D structures contain the same improvements and new features as Metal 3D

Metal 3D

Detailed ultimate limit state check reports

  • Metal 3D and CYPECAD’s Integrated 3D structures generate detailed ultimate limit state check reports of rolled and welded steel sections for the CTE DB SE-A (Spain) and CAN/CSA S16-01 (Canada) codes, and for cold formed steel sections for the NBR 14762 (Brazil) code.

    These reports contain all the checks carried out by the program for the section design and therefore constitute an important document with which the user can:
    • Verify the design of the sections
    • Optimise the design of the sections

    The level of detail of these reports also provides an informative document, allowing the user to know all the checks to which the section has been submitted.
    More information can be found on these documents in the detailed ultimate limit state check reports.

Joints

New bolted connections

  • Beam joint type: a main continuous element to which one or two orthogonal elements are pinned to it.
  • Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous).
  • Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous) with an orthogonal beam pinned to the web of the column.
  • Two beam connection (with or without a bottom haunch) fixed to the flanges of a column (continuous or non-continuous) with two orthogonal beams pinned to the web of the column.

New options for connection design

  • Stiffeners at haunch ends
    Stiffeners may be used at haunch ends in column-beam connections and at ridge connections even though they may not be required in the design calculation. These two options can be activated in the Options dialogue (Joints > Options) which now contains two tabs:
    • Bolts: Contains bolt design options. These options were available in previous versions.
    • Stiffeners: Contains the two new options that force the program to always provide stiffeners in column-beam and ridge connections.
  • Baseplate options
    The same design options that are used in the Baseplates module are used for the baseplate design in the Joints I module, except for the type of anchorage of the bolt to the plate. These options are configured in the menu Baseplates > Options.
    More information on the properties of the two Metal 3D baseplate design modules can be found in the Baseplates section.

Improvement in the joints analysis period

The time required for the joints design has been reduced with the use of multiprocessors (the user must have one of the two following modules: Parallel analysis with two processors or Parallel analysis with four processors).

Welded connection design in accordance to the ABNT NBR 8800:2008 (Brazil) code

Welded connection design has been updated for Brazil in accordance to the ABNT NBR 8800:2008 code (Projecto de estruturas de aço e de estruturas mistas de aço e concreto de edifícios).

Joints export in CIS/2 format

The option: Complete layout of the structure, including joints has been implemented. Therefore, it is now possible to export all the joints designed by Metal 3D to CIS/2 format, if the corresponding permits have been acquired in the user license. No special permits are necessary to export the geometry and properties of the nodes and bars; the user is only required to have the Metal 3D license.
