Dear colleague, You found the reinforcement request in the S16 column in the 2nd basement to be meaningless, however, can you make a meaningful comment on the positions of the centers of mass and stiffness in the 1st and 2nd basements, which is extremely meaningful? 2- There is frame formation only on the south and west facades of the 2nd basement. Could this frame defect, completely console on the upper floors, have caused the formation of extreme cross-section effects in the column you mentioned? 3- Could your columns in the already unbalanced frame system be overloaded to meet the earthquake loads because you did not use curtains in your building in the 1st degree earthquake zone? 4- It's amazing how you found the reinforcement request in a 30/60 corner column meaningless, while the column moments in a frame system with plenty of stud beams, where the load is moved, without paying attention to the column placements and directions, while the columns were screaming for help. .. Greetings and best regards. G.KÖSE
