Hello
How to build a single dof system which considers deterioration with the ability to change its ductility.
I would really appreciate it if the commands are proposed.
Thanks for your attention

Hi. My problem is about Steel01 four isotropic parameters. I want to know how these four parameters are used to make stress-strain diagram. How do they effect pressure and tension? I took a look at the some examples and arguments in OpenSees wiki figures but I could not find the exact equation for t...

Hi. thanks for your previous attention but my problem is still about yield point in spite of the reasonable ductility. I would appreciate it if you could help me. Actually I want to study different uniaxial materials behaviours and their strain stress diagrams. So I tried to made a simple model as a...

what about this one? it seems reasonable but still with problem about yield point: # units: N, m wipe # Create ModelBuilder (with two-dimensions and 2 DOF/node) model BasicBuilder -ndm 2 -ndf 3 node 1 0. 0. node 2 1. 0. fix 1 0 1 1 fix 2 1 1 1 # Define materials for truss elements uniaxialMaterial E...

I have a problem in my file that I can not find. this happens near yield strain point. help me please. I am really in troubles. # units: N, m # Remove existing model wipe # Create ModelBuilder (with two-dimensions and 2 DOF/node) model BasicBuilder -ndm 2 -ndf 3 # Create nodes # ------------ # Creat...

hi. sorry if I post here actually i do not know where should i post my problem but my problem has the same error: warning bandgenlinlapacksolver and this is my file: # units: N, m # Remove existing model wipe # Create ModelBuilder (with two-dimensions and 2 DOF/node) model BasicBuilder -ndm 2 -ndf3 ...
