Dynamic Analysis

Are you interested in our Modal Analysis add-on? Quickly and conveniently analyze natural frequencies as well as mode shapes for member, surface, and solid models.

The add-on includes an optimized input workflow. We have good news: All required input values are imported directly from the main program RFEM/RSTAB. You can also use powerful eigenvalue solvers (such as Lanczos, subspace iteration, and others) to calculate up to 9,999 eigenvalues.

Interested in a seismic analysis for your design project? Then the Response Spectrum Analysis add-on is right for you. Using the multi-modal response spectrum method, the program carries out a full seismic analysis so you can be sure of the stability of your project. You can create user-defined response spectra or automatically generate them from the various standards. Integrate the seismic results with other static load cases for a full structural design check.

An extensive library of accelerograms from seismic zones is also available in the add-on. You can use them to generate the response spectra as well.

Earthquakes may have a significant impact on the deformation behavior of buildings. A pushover analysis allows you to analyze the deformation behavior of buildings and compare them with seismic actions. Using the Pushover add-on, you can analyze the seismic actions on a particular building and thus assess whether the building can withstand the earthquake.
