Ground safety tension

In my attached project, although the max base stress is not exceeded at any point, it gives an error. Would you check?

Hello, In your project, the calculation method of buildings with 4.8.5 basements was calculated according to the "Calculation method with two loading states (4.8.5.1, 4.8.5.2, 4.8.5.3)". The base pressure values given in the minimum, average and maximum base pressure report are the results of which the process of increasing and combining has been applied. Foundation pressure values given for raft foundation finite element results are only intermediate values found from the superstructure solution. The difference is due to this. The values written in the Minimum Base Pressure, Average Base Pressure and Maximum Base Pressure sections should be taken into account as the base base pressure values. Good work

Do you have any suggestions for a solution, Mr. Levent?

-To reduce the base pressures, a raft foundation can be amputated, to reduce the weight of the building, lighter materials such as aerated concrete can be used instead of bricks in the wall elements... Good work

Thank you, Mr. Levent. I solved the problem with multiple conjugate winkler spring method and some ampatman.
