SA HELLO 1- Although the width and length of the curtain do not change, the reinforcements in the middle part of the P11 curtain increase as the floor increases. The program is adding exactly 10 cm^2 more reinforcement than necessary. Would this excess reinforcement not cause any problems while the project is being implemented, and would it be a problem if we reduce this reinforcement enough to save it? (I am reducing it as seen in the picture, but I am asking if there is a place I missed) I would be glad if you could help. In 2-beam raft, beam length / raft thickness should be like in normal floors (floor thickness / beam length = 1/3). I will be glad if you enlighten me. (If it is in ts500 or 2007, can you specify the location)
