Friends, I am trying to finish the project, which is the subject of the location in the link below. I solve the structure in semi-rigid diaphragm. But as in the picture, there is an excessive gap between the centers, what is the reason for this? I'm confused :( Current Thread Link :

Re: Extreme difference between the Center of Mass and the Center of Rigidity Hello When the calculation is made without touching anything in the project, the center of mass and the center of rigidity are close to each other. There is no difference as you give your image. Unver ÖZCAN
 
Re: Extreme difference between Center of Mass and Center of Rigidity I'm sorry I forgot to mention, while the stairs are not supported in the uploaded file, the result in the photo is after the stairs are supported.

You may have supported the ladder to hold horizontal displacements from the ground.

Hello, Stair support conditions are set incorrectly. As seen in the picture, there are fixed support assignments on the edges of the stairs, the stairs are held from these points, so the structure is also held. This naturally shifts the center of rigidity. If you edit the support conditions and analyze, you will have a problem. it will be fixed.
