How we can analyze a structure for different load cases (say dead load and wind load) and their combinations? I tried by creating different time series in same py file(refer below code). with same load im getting displacement 4 times more in Time series 2 compared to Time series 1 what can be the re...

Your observation is correct professor. The structure has some element not connected properly I fumbled with Y and Z axis . I thought Y as vertical axis. Now its working fine Thanks for your support model pot command has some issues in google colab environment (Im not testing in other environment) I ...

I missed basic input :) . Thanks for correcting me, Professor. But my problem is still not solved. Same error is coming after charging the supports and load to match 3 dof. Can you please again look into my code? In general we get matrix singularity problem for space trusses quite often in Staad pro...

Once again thanks for reply.

The model data and code is available at below google colab notebook link

Pl. review and suggest the corrections

Thanks for your reply. Im new to opensees so im struggling to understand what are the exact commands to be given for executing analysis of space frame Can you please suggest whether below commands are correct for a space truss analysis model('basic', '-ndm', 3,) # create SOE system("BandSPD&quo...

Can nay one help me with the analysis commands to be given ofr a space truss analysis?
