StruBIM Foundations is a tool to design foundations. With the supports of the structure, users can generate, design and check the foundation elements.
This tool is integrated in CYPE’s Open BIM workflow via IFC standard. Users can also import files in XML format.
Initially, StruBIM Foundations designs and checks foundations in accordance with the following codes: ACI 318-14, ACI 318-11 and ACI 318-08.
It generates drawings containing the on-plan view of the foundations and the description tables of the footings, pile caps and piles used.
More information can be found on the "StruBIM Foundations" webpage.

Norma Boliviana. Hormigón Estructural
REP-2014. Reglamento Estructural de Panamá.
Implemented in CYPECAD.
As of previous versions, when users selected to carry out a seismic analysis with the NSR-10 code (Colombia), they could choose amongst several microzonations:
As of the 2017.e version, the Microzonation of Cali of 2014 has been included (Decree 411.0.20.0158 of 2014).
The option, “Divide column”, which divides a column into two parts has been implemented in the “Columns, shear walls and starts” menu (Column Definition tab > Introduction). The option divides columns in such a way that the start of the column above is the top of the one below.
As of the 2017.e version, CYPECAD allows users to define linear trapezoidal loads.
As of the 2017.e version, users can define external precincts.
Local analytical models of the floor plans can now be generated, edited and analysed, with the 2017.e version. The local models allow for a floor of the global model to be analysed independently from the rest of the floors, improving the flexibility during the structural analysis. The design of the structural elements of the floors can be carried out with the forces of one model or another.
To generate a local model, select the “Generate” icon. There are several possible situations that affect the generation process:
If the global analytical model is not available, the model that is generated will be that of the first case, but without any information of the global model. In all cases, non-deformable zones at the top of columns will be generated as will the necessary trims at column and beam ends due to the dimensions of the nodes.
To edit a local model, the “Edit” button must be selected. The editing process of the model is carried out using an interface similar to that of StruBIM Analysis, where users can edit the discretisation size of the shells, fixity coefficients, stiffness factors, mechanical properties of the bars, acting loads...
The local analytical model can be updated in two ways:
Once the local analytical model has been generated for a floor plan, the forces of the model will be used, by default, to design and check all the elements contained in the plan. Using the “Edit” option from the floor plans list, users can indicate they wish to use the global analytical model again for all the elements of the plan.
Floor slabs are always designed and checked using the local analytical model defined for the floor plan. When there are floor plans with a local analytical model, StruBIM Design allows users to indicate, for beams and punching shear zones, whether the local or global analytical model is to be used.
The results from the analysis of the local model can be viewed in the Deformed shaped and contour maps window, and from the Slab forces and Beam forces windows.
It is possible to alternate between the view of the forces of the global model and the local model. As well as the forces, the displacements and stresses can be consulted.
Implemented in the 2017.e version is the design of post-tensioned slabs. This improvement has been created to design the passive reinforcement of post-tensioned slabs, having calculated the forces in the post-tensioning tendons (adherent or non-adherent), and whose properties have been introduced by users.
Users can introduce the path of the tendons, their definition, their stressing loads and their losses (instantaneous and differed). The program generates two post-tensioned load patterns (one with the instantaneous loss and another with the total loss) in which the deviation loads, due to the path of the tendons are introduced. The program also creates three loadcases, two equivalent to the previously mentioned load patterns, and one hyperstatic loadcase with the total loss.
Due to the path of the tendon, forces are produced acting towards the inside of its curvature. The program automatically generates these loads for each tendon. These loads will affect the floor slabs when the local model of that floor plan is analysed. The discretisation of the floor slab during the local analysis is carried out using triangular finite elements which are adjusted to the path of the tendons.
The post-tensioning effect is taken into account when calculating the reinforcement areas required in the slab. When a tendon crosses a critical punching shear perimeter, its effect is taken into account.
Floor slabs containing tendons will be checked and will be designed as post-tensioned slabs in accordance with the ACI 318-14, ACI 318-11 and ACI 318-08 codes.
In the dialogue box that appears when generating a local model, users can select to automatically generate post-tensioned load patterns. By activating this option, the post-tensioned load patterns, loadcases and combination groups are generated.
With each of these options, users can define:
Different reports are generated indicating the properties, elevation geometry and checks of the tendons.
The program also generates floor plans with the tendon distribution and dimensions selected by users in the drawing configuration. Users can also include the Properties table, the elevation properties table and elevation curves table.
The program now automatically designs punching shear reinforcement. In previous versions, the critical punching shear perimeter was only generated for columns or column groups that were not in contact with beams. During the design process, the program regenerates and automatically checks the critical punching shear sections. The design process can be executed from the Punching shear menu (affects only the selected floor) or from “Project > Design” (affects the selected plan or all plans).
The design of all the punching shear reinforcement can be carried out using the forces of the global analytical model or those of the analytical model defined for the floor plan.
The punching shear reinforcement can be designed using shear studs or stirrups. The type of reinforcement can be selected before the design process begins in “General data > Design options > Punching shear”.
Two new design options for columns have been implemented:
By activating these options, the number of bars remains the same or is reduced on higher floors, and the diameter of the bars remains the same or is reduced on higher floors.
Users can configure the program to generate additional warnings to those provided by the code.
In columns, if the “Continuity criteria” option is activated, a warning is generated for each column span when the number or the diameter of longitudinal bars is less than that of the span above.
For columns, walls and beams, users can indicate for a warning to be generated if a certain steel reinforcement area, defined by them, is exceeded. This is an additional warning or check to those required by the code.
Users can now import reference lines which make up a grid during the creation process of the project using a BIM model.
The option to check shear outside the plane in walls is not obligatory; in previous versions, it was.
When users indicate for it to not be checked, the check report of the wall will indicate the acting shear, the shear resistance of the concrete section of the wall, and if necessary, the required reinforcement area.
As of the 2017.e version, a new attribute has been added to loadcases: the “Type of analysis”.
Users can select between a static analysis or hyperstatic analysis. In previous versions, a static analysis was carried out for each loadcase. The hyperstatic analysis is required when structures are designed with post-tensioned slabs. Even though users can choose to carry out a hyperstatic analysis for any loadcase, this type of analysis is logical when there is equilibrium amongst loads that are introduced, as occurs with post-tensioned cases, since the supports of the structure are eliminated.
Users can define non-deformable zones in shells. When a non-deformable zone is introduced on a shell, there is the hypothesis that that part of the shell is infinitely rigid. Non-deformable zones can be used to simulate the size of nodes. When a local analytical model is generated from StruBIM Design, a non-deformable zone is placed at the support of each column, with the same size as the column.
The program now calculates the dimensions of nodes during the import phase of a model. Trims at bars with the same size as the nodes, are assigned. By default, the trims at ends have an assigned stiffness zone factor equal to zero.
Users can define factors that modify the stiffness of shells. Using these factors, the axial, bending and shear stiffness can be modified, for the local axes of the shell.
When the layout of shells is defined, users can choose whether or not to consider the eccentricity of the shell during the analysis of the forces.
The program menus have been reorganised. The options and buttons of the program have been groups into three menus or tabs: Geometry, Loads and Analysis:
As of the 2017.e version, users can open and analyse several StruBIM Analysis projects simultaneously.
These new features have also been implemented in CYPELUX RECS (Portugal).
As of the 2017.e version, CYPELUX uses the Radiance analysis motor (developed by the Lawrence Berkeley National Laboratory) to carry out the lighting analyses for normal and emergency lighting. This new analysis methodology provides more precise results for indirect lighting, carry out the discretisation of non-point light sources and view realistic light scenes.
Thanks to the inclusion of the Radiance analysis motor in CYPELUX, users can represent the lighting effects produced by the installation of normal or emergency lighting on a precinct.
To do so, the View option has been added to the program. This option contains three new buttons:
The autosave option has been implemented in the 2017.e version of CYPELUX. The autosave can be carried out in two ways:
Neither option is activated by default. Hence, users must activate the option they wish to apply.
As of the 2017.c version, CYPESOUND and its specific versions for some countries, import, from a BIM model, the noise produced by the openings of ventilation systems. Users then had to specify the other properties that specify the noise produced by these openings in a precinct.
As of the 2017.e version, CYPESOUND, CYPESOUND CTE (Spain), CYPESOUND RRAE (Portugal), CYPESOUND NRA (France) and CYPESOUND DRAPDE (Italy), automatically calculate the following parameters: “r” (radius of the largest sphere that can be inscribed in the precinct) and “D” (directivity factor of the source) of the grilles and diffusers. This way, the noise generated by the HVAC duct networks in the precincts can be obtained more easily.
The analysis is carried out during the import process of these elements, based on IFC files, hence the CYPESOUND project must import them from the BIM model (either because the project is linked to a BIM model or, if it is not, because the BIM model has been imported without maintaining the link). Logically, the imported BIM model must include the design of the duct installation for heating, ventilation and air conditioning. CYPETHERM HVAC allows users to export these installations to the BIM model.
The 2017.e version of CYPETHERM LOADS and CYPEHERM EPlus has improved edge management. As of the 2017.e version, users can choose the code with which edges are to be analysed, so they can be detected as being thermal bridges (ISO 14683, ISO 14683- Italy, HE1 2006, HE1 2013, RT2005/2012 and REH).
This improvement has also been included in CYPETHERM RT2012 (France) and CYPETHERM RTExistant (France).
In the 2017.e version, CYPE has updated the EnergyPlusTM analysis motor in all the programs which use it: CYPECAD MEP, CYPETHERM HE Plus and CYPETHERM EPlus and the new CYPETHERM RECS Plus. This way, CYPE uses the latest version that is available of the analysis motor of the US Department of Energy (DOE): version 8.6, published on 27th September 2016.
Columns, doors and windows defined in the IFC model are now imported to CYPETHERM HVAC. This feature not only aids in understanding the architectonic model on which the installations are being designed, but they are also taken into account when inserting air conditioning equipment.
As of previous versions, using the “Generate circuits” button, the program detects all the spaces for which a design heating temperature has been defined, and automatically generates the radiant floor circuit. As of this version (2017.e), the generating process interprets that the columns in the BIM model are obstacles and the doors are an entry point for the pipes of the radiant floor.
Remember, once the radiant floor has been generated, the installation must be designed so the program can calculate the area and power generated by each circuit.
Users can use flow meters in the hydraulic balancing of the manifolds of the radiant floor; only balancing valves were available up to now.
The behaviour of the connection pipes of the radiant floor (from the circuit to the manifold) has been improved. Now, the thermal contribution in the precinct through which these pipes go through is accounted for and graphical representation problems have been solved.
In the 2017.e version, the “Generate thermal emitters” option has been implemented. If this button is selected, the program provides a radiator below each window, by default, thanks to the interpretation of the BIM model.
The radiators that are placed are not designed. It is not until users press the design button that the program will select the number of elements each radiator requires to cover the heating thermal load.
The definition of the thermal emitters has been simplified by substituting the “average temperature”, which was indicated up to now, with the entry and outlet temperatures.
The thermal emitters adopt the internal design temperature of the precinct in which they are located. Users can block this temperature in the emitters.
When users select the “Generate fittings” button, a new dialogue appears where the generation process of the duct ties can be configured:
If there are any intersections between the columns of the BIM model and the ducts of the installation, the program will warn users with an error message.
