Question:
Is it possible to define member nonlinearities for beam members?
For example, can I define a member that absorbs all internal forces, except for the compressive axial forces?
Answer:
Yes, you have to activate the "Nonlinearity" tab in the "New Member/Edit Member" dialog box; see Image 01.
In the "Nonlinearity" tab, you can then define a new member nonlinearity; see Image 02.
