Section Calculator

The Section Calculator is a very powerful feature that allows you to import any geometric section into the software in order to be used in the structure. The software calculates the geometric and mechanical properties of the section and saves it within the custom section spreadsheets. The section created is saved and can later be used for any model.

Static Analysis

This module allows linear, non-linear static (P-δ and P-Δ) and analysis with releases for 2D and 3D structures. The results of the other modules (moving load analysis, spectral analysis, etc…) may be combined to create combinations to run in a static analysis.
The "Batch Analysis" function allows starting the analysis of several models at the same time without having to open each file. The software also provides a “Results Comparer” which makes comparisons (in the same table) of results for several different files.

For static analysis, we find the following main features:

  • Cable elements with large deformation
  • Configurable Standards: resistance factor, standard interaction and tension/compression as well as buckling curves
  • Specific equations for the computation of effective length coefficients for compression members according to the type member
  • Standard combinations, damaged combination, and combinations to calculate deflections
