Add-ons for Dynamic Analyses

  • EC 8

Modal Analysis | RFEM 6 / RSTAB 9

The Modal Analysis add-on allows you to quickly and comfortably analyze natural frequencies and mode shapes for member, surface, and solid models.

All required input values are imported from RFEM/RSTAB. Powerful eigenvalue solvers (e.g. Lanczos, subspace iteration, etc.) are available to determine up to 9,999 eigenvalues.

Response Spectrum Analysis | RFEM 6 / RSTAB 9

In the Response Spectrum Analysis add-on, the seismic analysis is performed using the multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or user-defined. From this, the equivalent static forces are generated.

The add-on includes an extensive library of accelerograms from seismic zones. These can be used to generate response spectra.
