CYPE 3D

As of version 2026.a, CYPE 3D will include a modal vibration analysis module, an essential feature for evaluating how a structure responds to dynamic loads such as wind, traffic or earthquakes. The program carries out a modal analysis of the structure, showing detailed and visual results that optimise the design to ensure that it remains within acceptable limits.

As of version 2026.a, CYPE 3D will include the option of considering seismic action by means of a spectral modal analysis when launching a non-linear analysis. Non-linear combinations (NLC) involving seismic loads can be defined. Once the analyses have been carried out, we can consult the Justification of seismic action report, and view the groups of combinations generated and the results of the spectral modal analysis for each of them.

In CYPE 3D, a new interface has been implemented with a ribbon at the top, replacing the previous interface based on drop-down menus. This streamlines access to the different tools in the program and improves the user experience. The options visible in the ribbon depend on which tab is open.

It is now possible to consult the ground bearing pressure diagrams at the base of the footings in CYPECAD and CYPE 3D. As a result, the suitability of the solution adopted for the foundation can be assessed, as well as the distribution of loads on the ground and the behaviour of each footing.

A new option has been added in the column editor that can be used to design the transverse reinforcement of all columns while maintaining the existing longitudinal reinforcement. The option, called "Trans. reinf. all", is available in the "Redesign" group.

New options have been implemented to configure the references of the elements (nodes, bars, parts and shells) according to the user's preference. In addition, the references of previously entered elements are maintained when deleting or adding new elements.

Should the modal spectral analysis be selected to consider the effect of earthquake, the maximum response of the structure in the seismic load is estimated by combining the results of the modes of vibration by means of the Complete Quadratic Combination (CQC). In versions prior to 2026.a, only seismic load stresses, reactions, displacements, etc. could be checked for the seismic scenario by mode. This is now also possible for the CQC modal combination.

Two options are provided for automatic saving of the work (Configuration menu > Auto Save Options). Two modes can be activated individually or simultaneously: "Automatically save every ... minutes", which saves the job automatically every time an action occurs in the environment and the specified time interval elapses, and "Save after analysing or designing", which saves the job automatically if the structure is designed. Neither of the two options is activated by default, so users must activate the desired options.

In version 2026.a the following codes have been implemented in the CYPE programs:

  • Concrete structures: BRITISH STANDARD BS 8110-1:1997 for Malaysia and Singapore in CYPECAD, CYPE 3D and Foundation elements.
  • Rolled and reinforced steel structures: ABNT NBR 8800:2024 for Brazil in CYPECAD, CYPE 3D and Portal frame generator.
  • Loads on structures. Wind loads: DPT 1311-50 for Thailand in CYPECAD.
  • Loads on structures. Seismic loads: DPT 1301/1302-61 for Thailand in CYPECAD and CYPE 3D.

 

Version 2025.d includes the option to select the calculation mode of the pile sinking resistance in the module "Piles I: Calculation of sinking load":

  • By indicating the "Geotechnical parameters" (available since previous version -2025.c)

  • By indicating the "Allowable bearing pressures"(implemented in version 2025.d)
    This option is used to calculate the pile considering the allowable bearing pressures defined in the geotechnical study. This feature also introduces the possibility to include the effect of "negative friction" by entering negative values.

This selection is made in the "Advanced setup" dialogue box (Job menu > General data > "Foundation elements with external fixity" option > "Advanced settings" option).

Norme Tecniche per le Construzioni NTC-2018.

Implemented in CYPECAD, CYPE 3D and Portal frame generator for checking rolled and reinforced steel sections.

As of CYPE 3D version 2025.d, the properties panel of the selected section includes information on its linear weight.
