Re: Could you please review my project and tell me what's missing and my mistakes In addition to what Ünver said: You should combine more beams in the stair hall of the building. There are already ventilators, WCs, bathrooms in that area. Stair hall flooring live load is faulty. There is a lot of strain on the balcony, it seems more correct to turn with a beam and make normal flooring instead of console flooring. The carrier system behavior coefficient is incorrect. Convert beams (K36-K37) (k19-75) (58-59) (74-16) (68-10) (70-71) (41-91) (92-93) into single beams. Make curtain P14-P15 a single curtain. Beam loads include both wall and live loads. There are some errors in the fundamentals. (s24, below s26, CF64 foundation, P31, p32 under-curtain foundation and p33-34, etc.) In the basement floor, although the p08 curtain does not continue on other floors, the basement is not marked. You can apply the live load reduction factor. I think it would be a better choice to put curtains in some places instead of making so many stud beams. N. YILMAZ
