Hello, I have done a study on slab flooring in the appendix. I need the ideas and advice of friends who have done this kind of project. Actually it was solved with a semi-rigid diaphragm and it did not give an error, but since the size of the cde file grew, I saved it with a fully rigid solution. Please consider this. I beg you to review. thanks
