Answer:
The bolt stiffness does not depend on the strength grade, and for most steel types, it is 21,0000 N/mm². Therefore, you can select S235 as the bolt material to consider the stiffness of the bolt.
Selecting Material for Bolt Connections
I would like to use FEA to calculate a bolt connection in RFEM. Does the material library provide an option to select the material according to the strength grade of the bolt (for example, 8.8)?
