  • Frequently Asked Questions (FAQs)

Is it possible to set a plastic calculation of the internal forces in RSTAB, or are the internal forces exclusively calculated elastically?

Answer

In RSTAB, it is also possible to determine plastic internal forces. To do this, you have to select a plastic hinge as a nonlinearity by using the member properties (see Image 01). However, this does not include an interaction of the plastic internal forces. Another possibility is to set releases with nonlinear properties directly. However, with this method, you have to estimate beforehand where these hinges are formed.

RFEM provides the option to select a corresponding material model (see Image 02).
