Dear Kurcel; First of all, I understand from your model that you have a great lack of experience. Your main mistakes Your load definitions (Beam load, hollow block load) Hollow geometry The difference between the building's center of mass-rigidity is your crossing the 8 m gap with 25/50 beams. As if that wasn't enough, you should stick hollow beams to this beam. As if the room is not enough, you need to turn the strong side of the columns that this beam is stuck in to the other side ... and make these mistakes in a 5-storey building. Mr. Kurcel, these are serious mistakes, maybe you should do an internship in a good project office for a while and review your lecture notes. If you are not a civil engineer, it would be better not to bother and leave it here. Good work
