Thank you for your answer

Hi
I am going to run a time history analysis for a 2D model with leaning column. should I assign the floor mass to the leaning column joints or all the mass needs to be assigned to the frame nodes?

These materials have very different unloading behaviors. Thank you for your answer. The web plate of self-center steel plate shear wall simulated as two set of parallel uniformly spaced truss element which inclined in direction of α and – α. The unloading paths of two material are the same, but as ...

Hi everyone I’m trying to assign a tension only material to truss element for simulation of steel plate shear wall. First I used Here is the two material that I used uniaxialMaterial ElasticPPGap with zero value for $gap and then I tried uniaxialMaterial Hysteretic with negligible values in compress...
