Hello there; I reviewed your project. The floors that usually cause problems are the floors that are attached to the curtains where the stairs are. Stress concentrations usually occur in these regions due to earthquake loads. Therefore, in some cases, adding additional reinforcement for these areas may be a solution. Best regards...
