I finished the modeling of my project in the link I gave below, but the quantity was more than I expected, I couldn't see an error, but there must be something missing somewhere. I don't understand why you're thinking. Most importantly, what are you comparing it to? Columns work at minimum (1%)... Panels work at minimum. There is almost minimum reinforcement in beams. Reinforcement can be considered normal for a 16-storey building on raft foundation. Maybe this can be said. The sections you chose If it is too big, you may be adding extra reinforcement due to the minimum reinforcement. In addition, the rigid basement floor number will be -1. Entered 0. When it is corrected, there is a decrease of 200 kg. There are warnings that need to be corrected in the geometry control. Apart from these, I did not see any problem in terms of the question you asked. Good studies
