You stuck 50/40 beams into 50/35 beams. If there are 50/40 beams, it means that there is no flatness on the ceiling. then make all the beams 40 so you will get rid of the deflection problem in many beams. Your floors are thick, adding additional load. Instead of 15cm flooring, you can make 10 cm. You will save a significant amount of load. I'd make the tiling teeth 15 if I were you. In addition, when the beam is 40, the teeth can also be 40, so you can get rid of many deflection values. Since there are so many openings in the floors, the probability of having a wall on it is very high, so shouldn't the floor loads be 350 kg/m2? Are your wall loads low, especially the outer beams? Enter the ladder loads into the system. Your curtains are insufficient and ineffective. You have made a single rib console floor. (Suspended D1) We recommend that you dissolve the semi-rigid diaphragm. We recommend that you solve the superstructure interactively. Increase the foundation thickness (or expand the relevant columns)
