relative floor drift problem

Hello there; In the attached project, although Rm and Km are not far from each other, there is a problem in floor drift. It says I need to increase the rigidity of the system. When we look at the project, it seems rigid enough. What should I do? Although the system is ribbed, I tried to make cantilever beams and the corresponding beams 25x50-25x60, I cannot trust 32 cm high beams for consoles. Is it a factor in this case?
 
Hello, In the project, the soil bed coefficient was entered as 40 t/m3. The parts of the beams between some columns are named differently. For example beams between columns S100-S105 and S105-S93.
