In the attached project, it gives an error on the ground floor curtain and two beams. It gives excessive reinforcement compared to the upper and lower floors. It differs greatly even with the almost symmetrical curtain on the same floor. Have I misunderstood some definitions? I would be glad if you can help me urgently. Note : I recorded after full rigid analysis to reduce the size. I solve the system as semi-rigid. The errors I mentioned occur after semi-rigid analysis.
