The deflection limit on the floor is exceeded. I couldn't fix

[erşahinler]

In my project, where I will perform the building with basement + 3 floors, 1 floor on the left and 2 floors on the right will be added. I drew it as it is in place, but the floor between the two stairs on the right does not save. I increased the slab thickness to save it. I increased the cross section of the beam. But it doesn't save. What can I do. I would be glad if you help. Project link is below.

Hello, The findings and suggestions for your project are as follows; -In your project, a superstructure interactive solution has been made, and a single and continuous foundation has been used together. In singular foundations, superstructure interactive solutions are not made. Therefore, the analysis model is formed incorrectly. In the current situation, it would be appropriate to make a solution without superstructure interaction. - It is convenient to analyze the blocks in separate project files. -2nd. Instead of the D01 eaves slab on the floor, it would be appropriate to define two separate slabs by dividing them by the slab edge from the dilatation point. - It would be appropriate to select the "Rigid diaphragm creation" option from the properties of the floors with negative elevation in front of the stairs and in the intermediate landing. Good work
