Soil tension and reinforcement insufficient errors in raft foundation

HELLO... In my project, which is located in the 3rd EARTHQUAKE ZONE with 11 floors, I could not provide the ground safety tension in the Raft Foundation... Also, I am getting the error of insufficient reinforcement. I chose Top-Bottom Flat Rebar. I've fixed issues with Additional Accessories. I deleted it again, increased the thickness and width. I went up to 110 cm thick and could not fix it. WHAT DO YOU RECOMMEND I DO? NOTE: I am doing dilatation solution, the version I am using is 7

If you add your project, we will help you.
 
Hello My suggestions; -- Since your floor group is C, you need to solve the superstructure interactively according to TDY 2007 2.2.1.5, -- You can increase the ground safety stress by 50%, -- Remove the ticks on the raft floor, -- Change the concrete value to C30. When these are done, there are shear errors and reinforcement deficiencies in beams and curtains. I suggest you solve the semi-rigid diaphragm by adding curtains. You make the final basic edit.

Solve the foundation analysis with superstructure interaction. There is an opportunity to increase the earthquake loads by 50% in C group soils. It would be helpful if you mark it as well. Enter the wall loads on all beams of 0.8 and reanalyze the wall loads which should be extra load. Increasing the thickness of the raft is useless after a point other than unnecessary weight. Also, please review the frame system in the x direction, only 1 frame is formed.
 
Additional info; In the project you added, the mat tile edges do not create a closed area. For this reason, the mat flooring is formed incorrectly, the columns S06 and S12 are not connected to the raft foundation. Good work
 
Levent, I noticed what you said before and corrected it. Also, there is dilatation in the column part you specified, so I did such a process on the floor edge drawing. I'm checking the other ones as well. Thank you for your interest...
