Intensive additional reinforcement in the area where the elevator curtains are located

[xavi40]

Good evening. This is how the design was formed in the project I have attached. In the area where the elevator curtains on the raft floor are located, additional reinforcement is intensely formed. How can I optimize this. What should be the choice of reinforcement. Also, how would it be appropriate to model the 45/25 long curtains at the end of the elevator curtains (Is it more correct to enter as a column). What are the mistakes or suggestions in the project?
