beamless raft foundation calculation; I know that in the plane where the calculation axis passes, calculation is made according to G+Q and additional reinforcement is added at moments relative to other combinations (1.4g+1.6q, +-ex1,......). My problem is this. Although I use earthquake loadings in the account outputs, the n, mx, my reactions from the columns to the foundation from the building inspection company and md are not the same. I am trying to calculate md according to the given combination of the mx and my values of the column where additional reinforcement is thrown.

Calculation is made according to the most unfavorable loading combinations, not only the vertical loads in the direction where the calculation axis passes in the beam raft. If larger effects occur at another point, additional reinforcement is thrown here as well. It cannot be expected that the calculation moments in the raft flooring and the n, mx, my coming from the column effects are the same. In raft flooring, the design is made according to the most negative combinations, taking into account the ground effects.

Thank you very much Mr. Levent. I hope I can explain it to the gentleman at the building dent.
