Hello there; Although it is quite difficult to obtain relative floor drift values in ZE floors, it is not impossible. A few suggestions for your project can be listed as follows. 1- Soil class can be changed to ZD by making soil improvement. (This may be costly for the building) 2- To balance the deformations of the system by increasing the rigidity of the floor diaphragms (floors were arranged as 20 cm in two floors, and the beams were arranged as 30/60) 3- Not to use the Structure Foundation interaction option (it was done this way in your project, in order not to exceed the max floor pressure) apartment building) 4- Application of jointed wall detail in accordance with TBDY2018 (you have already chosen this way) 2-3-4 . The project in which the items are applied and in a state of recovery is attached. Best regards.

Hello, In the first project you added, there is a missing As message due to the need for additional raft reinforcement. It is appropriate to use 18 gauge reinforcement. If you do not want to use reinforcement higher than 16 on the raft basis, you can increase the thickness of the raft. Alternatively, an additional 10 cm spacing is left in the raft parameters. You can reduce this spacing in a controlled manner by fulfilling the concrete pouring conditions, or you can place double rows of reinforcement yourself. Having your structure on ZE ground is the highest penalty for storey drift. If you examine the displacement of the structure in modal 1 and modal 3, you can observe that the bearing elements on axis 1 are insufficient. Therefore, you need to enlarge the corner columns on the 1 axis. You can turn it into a curtain. In the Y direction, the S8 column needs to be enlarged. Provided that joint wall detail is applied to TBDY2018, for your existing beam-column system, it is necessary to enlarge columns S1 and S3 sufficiently in the x direction and column S7 in the y direction. Mould plan with relative floor offset: Relative story offset report: Your building is in ZE class, the bed coefficient is low-superstructure interactive solution, the overhang on the 2nd floor shows the frame continuity on the upper edges. are the factors that increase the cost of the building according to our old habits.
