Dear colleagues, I could not fix the connection error of the S05 column on the upper floors except the basement in this project, can you help me urgently
solution suggestions: You can add curtains to the system in the 1-x direction. You can make 2-concrete class c30. 3- Solve the system as a semi-rigid diaphragm. i haven't tried this. because it gave a jacobian error in the analysis. I couldn't find the reason.
