Export to Tekla® Structures
The following elements have been implemented when exporting to Tekla structures:
- Concrete beams and columns of CYPECAD, and concrete bars of Metal 3D and integrated 3D structures of CYPECAD. The elements that are exported have rectangular, circular, T or L sections.
- Special extruded aluminium sections
- Trims at hollow section ends processed by the new Joints V module.
These elements are exported as macros type “Tube-Saddle+Hole” for versions 15.0 SR1 and 16.0 of Tekla Structures.

Plane assigning to the tops of walls
Horizontal or sloped planes defined in the Sloped floor slabs/El. Changes (Column Definition tab > Groups > Sloped floor slabs/ El. Changes) can now be assigned to the tops of walls. This way, the user can assign an elevation change or a slope to the top of a wall even if it does not support a floor slab.

Lateral buckling of the top flange of steel beams
In previous versions, CYPECAD checked the bottom flange of steel beams not supporting floor slabs on that flange along their entire length, such as for example: beams below slabs, isolated beams, beams next to openings, or beams whose top flange projects above the floor slab.
Checking of both webs is activated in the Options for steel beams dialogue box which can be accessed from the Job menu in the Beam Definition tab > Beam options > Steel beam options.

Different building use for each floor group
Now in CYPECAD, different use categories can be defined for each floor group of the structure. Examples of use categories include: dwellings, shops, warehouses, garages, etc. The number of use categories the program allows to choose amongst depends on the selected code. For example, the use categories for the Eurocode are:
- A. Domestic and household
- B. Offices
- C. Meeting areas
- D. Shops
- E. Warehouses
- F. Vehicle weight <= 30 kN
- G. 30 kN < vehicle weight <= 160 kN
- H. Roofs
For the program, a use category consists of a group of live loadcases, be they automatic or additional, which combine with the other loadcases that have been defined in the job with the same combination coefficients.
This way, the live load combinations for each use category can be analysed correctly amongst all the use categories and the remaining loadcases of the job for which different use categories exist per floor.
The use categories can be selected in the Additional loadcases (special loads) dialogue box within the General data window (Job > General data > Additional loadcases (special loads)). The categories that are selected in this dialogue box are assigned to each floor group in the Edit groups dialogue box which opens by selecting the Loads menu within the Beam Definition tab > Loads in groups or in the Column Definition tab > Floors/Groups > Edit groups.
Different use categories can also be defined for a floor group. To do so, simply do not introduce a live load for the group and once the geometry of the floor group has been defined, introduce the live loads at different positions on the group, assigned to the corresponding loadcase.
The user should bear in mind that the more use categories are defined for a job, the more loadcase combinations the program will create, and so, the time taken to analyse the job will be substantially longer.

Matrix foundation calculation
Changes have been carried out in the calculation method used to obtain the forces of footings “with external fixity”, for footings, pile caps, strap and tie beams.
The current design can differ from previous versions. Now, once the reactions at the base of the supporting elements of the structure are obtained (columns, shear walls and walls), a model is created will all the foundation elements “with external fixity” and its beams, represented by its stiffness matrix. The stiffness matrix, together with the loadcases defined as loads acting on the foundation (reactions that have been obtained), is resolved using frontal methods to obtain the displacements and forces of all the elements. By doing this, the stiffness of all the elements intervene and interact with one another.
