Gravity Analysis results not matching with that of SAP2000

Post by ankurjain1992 » Sun Aug 23, 2020 2:24 pm

Sir, I have done a Gravity Load Analysis on a 1-storey frame model in STKO as well as SAP2000... But I forund that Support reactions are not matching with that of SAP2000 model....

All loads applied are same in both STKO and SAP2000 ....

Kindly help me finding the error why STKO (Opensees) is showing different result that SAP2000...

TCL file is attached and SAP2000 file is also attached.

How can we connect two non-linear link elements in parallel i.e. Wen and Gap type elements in SAP2000.

You can create your 2 uniaxial materials.
Then you can create a uniaxial Parallel material where you combine the previously create materials.
Finally use the parallel material within your zerolength element.
