Modal Analysis for RFEM 6 / RSTAB 9

Have you already worked with the Modal Analysis add-on? It allows you to quickly and conveniently analyze natural frequencies as well as mode shapes for member, surface, and solid models.

Would you like to speed up the input of values? We have good news: All required input values are imported directly from RFEM/RSTAB. Furthermore, you can use powerful eigenvalue solvers (such as Lanczos, subspace iteration, and so on) that you can use to determine up to 9,999 eigenvalues.

Response Spectrum Analysis for RFEM 6 / RSTAB 9

Do you want to carry out a seismic analysis in your project? Then the Response Spectrum Analysis add-on is just right for you. Using the multimodal response spectrum method, the program carries out seismic analyses so your project is on safe feet even in a case of emergency. You can create the response spectra required for the calculation in compliance with the standards or user-defined. The program use them to generate the equivalent static forces.

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