Is a nonlinear calculation performed in the RF-/DYNAM Pro add-on module?

Answer

In the add-on modules Natural Vibrations, Forced Vibrations, and Equivalent Loads, a linear calculation is performed. Nonlinearities, such as failure under tension or nonlinear materials, are ignored. For example, cables or tension members are replaced by the member type Truss. This results from the calculation methods: Both the natural vibration analysis and the response spectrum analysis are purely linear methods.

The add-on module Nonlinear Time History Analysis provides a nonlinear time history analysis of time diagrams (any excitation of the structure) and accelerograms (excitation of supports) by means of an implicit and explicit analysis. Here, many nonlinearities that can be defined in RFEM or RSTAB are considered.
