Is it also possible to use nonlinear material behavior in the time history analysis?

Answer

To consider nonlinearities in Dynamics, you need the addition of a Nonlinear Time History Method in RFEM / RSTAB. This addition is different in RSTAB and RFEM by the type of nonlinearities to be applied.

RSTAB nonlinear time history method:

Nonlinear member types such as tension and compression members as well as cables

Member nonlinearities such as failure, tearing, and creeping under tension or compression

Supports nonlinearities such as failure, friction, diagram, and partial action

Nonlinearities of hinges such as friction, partial action, diagram and fast in case of positive or negative internal forces


RFEM Nonlinear Time-Course Process

in addition, you can work with nonlinear material behavior
