Hello My Suggestions -- There is an insufficient number of dynamic modes error in the general report of the earthquake regulation. --In this case there seems to be an error in the raft alone. -- If the number of mods is increased, that is, if this stage is passed in the account, I think there will be more errors. --foundation beams are faulty, they overlap if you make ampathes on the foundation beam and make a raft foundation next to it. --The columns are not seated on the raft beam as in the 4 axles where the raft beam has passed by the column. --The basis of the curtains, which I think is the elevator, is faulty. --Won't the elevator curtain be hollow on the floor? --I think there is a ladder around it, but the ladder is wrong with such a model. --There are a lot of short beams, and when the number of mods is increased and the calculation is made, there is a high probability of problems here. --Concrete C45 is a separate problem in providing this concrete. I suggest you make a raft without beams for a 25-storey building foundation. --Why are the floors 20 cm? increased the weight a lot. It would be appropriate to reduce it. --It should be essential to create a frame in the building, why did you make a short console in front of the halls? The columns can be brought forward a little to form a frame. --Addition of 4 curtains of 527 cm, which are not connected to the beams outside the building. Do what I say, let's see if it balances out. Unver ÖZCAN
