Hi Everyone,
I have an issue with SAP2000 tendon modeling. I currently have my own stress-strain curve that I put into the material property data form for my Tendon with a Fy=138ksi and Fu=160ksi and is represented in my user defined curve. I have also set the hysteresis type to Kinematic
I have assigned my tendons to use this material but for some reason when I put loads onto the structure with the tendon, the tendon stresses go beyond +/-160ksi in a linear path and have no energy dissipation when I put in cyclic loading (multiple load cases going in opposite direction). Is there a reason the tendon is not following the assigned user defined stress-strain curve in the nonlinear material data?
It feels like the tendon is not performing nonlinearly. I have read in the SAP2000 models that i can assign axial hinges to tendons but there is no option for me to do so like you can for frames.
Any advice would be appreciated.
Thank you!
