Thank you, the problem with rib flooring has been solved. But since I have just started drawing projects, I have a lot of trouble designing stairs and I don't know what is wrong with my project. 1- In this project, I need to design a semi-revolving staircase that goes up to the mahvil floor, but I could not do it, at the same time, I did not know how to transfer the load of the stairs to the building 2- how should I give the live load on the mahvil floor 3- I have intermediate columns on the mosque floor but removed at the mahvil beams, which causes a lot of deflection in mahvil beams. There is a 110 cm console (balcony) on the 4-mosque floor, and I threw 35/45 beams there, do you think it makes sense, can you help me with my problems?
