Hi,
I am doing static pushover analysis of a 2-story 2-bay frame, but facing problems with convergence.
I have used ZeroLength element as inelastic bending spring at the bottom ends of 1st story columns.
For beam-column joints, I’ve used Joint2D element and uniaxialMaterial Hysteretic.
Besides I’ve used elasticBeamColumn elements.
Could anyone please help me with this? I don’t understand why the model is not converging. I’ve tried different system, numberer etc. If anyone is interested to help, i’ll send the tcl file.
thanks and regards
Nassif
