Dear STKO
I made an error while extracting the pier top displacement time history curve. The displacement time-history curve of the fourth node in the STKO model is inconsistent with the calculation results in opensees (the picture is in the attachment). May I ask why and how should I modify it?The ...

Thank you for your reply, which is exactly what I need. The problem has been solved, thank you again

About your third questionIn ,the bridge model, the local coordinates of the twoNodeLink element are consistent with the global coordinate direction. The three directions of the local coordinates of the twoNodelink element in the source code correspond to three uniaxial materials. Therefore, I want ...

Thank you for your reply, which helps me a lot! I will carefully check the model error, thank you for your patient guidance.

Dear STKO team,
Hello! When I use STKO to establish a full-bridge model according to opensees source code to study its seismic response, the model does not converge, showing "Large trial strain". May I ask why such a situation occurs and how can I modify it to solve this problem?
I have uploaded ...
