Hi, I modeled a OCBF with many nodes at each beam-column intersection in order to pin the beams (release their end rotations since they are force-based BCE). I wanted to constraint all these nodes horizontally to a floor master, while also constrain them vertically at each beam-column intersection m...

Hi,

Try "basicDeformation" for the BCE elements.

Also, did you wipe() the domain after the analysis? recorders need the wipe() command at the end of the analysis.

Haha, got the solution.

Updated OpenseesPy from 3.2.2.9 to 3.2.2.10 and everything goes fine again

Can you provide a minimum working example showing the issue? Thanks! Good Morning Prof. Attached is a simplified example, everything works fine in tension (where the loads have the same sign of the displacement) but when the loads should became negative, the load factor goes to "0". I was...

Hey, Some months ago (before last update) I was able to get negative outputs from this command, but now it just prints positive values and no negatives... All negatives values are now "0". This happened when applying a cyclic loading to elements (truss, fbc, etc) to calibrate buckling. Now...

This is a late response to this post, but I think that maybe the problem is that node 9 is a constrained node in the diaphragm and then it is defined later as a retained node for the shear + moment transfer. Retained nodes cannot be used as constrained nodes in other constraint definitions. That is...

Hello everyone, I'm testing OpenSeesPy (new to Python btw, but I have time), and I was checking the plotting features and there are two that didn't work, I hope its just me. I installed Anaconda, and under Spyder I installed Openseespy and updated it to the version 3.2.2. Then on my -simple model sc...
