Gerhard Rehm Modeling | Structure RFEM RSTAB

I would like to calculate a screw connection in RFEM using FEM. Is there a possibility in the material library to select the material according to the strength class of the screw (eg 8.8)?


The stiffness of the screw does not depend on the strength class and is 210000 N / mm² for most steels. It can thus be chosen as the material of the screw S235, to take into account the stiffness of the screw.
