HELLO I'm getting a max offset error on the basement floor columns. 15 reinforcements on the ground floor and 45 reinforcements on the basement floor . this problem happens in almost every of my projects. I wonder if there is something I missed or did not know while modeling. Can you help with this. Thank you .

-When the columns of the 2nd basement floor are examined, it is seen that the columns are generally forced according to the cross-sectional effects formed at the lower ends of the 1st basement floor. On the other hand, column reinforcements are added in the middle region. For this reason, while the column is being reinforced, the design effects of the lower end of an upper floor and the upper end of the existing floor are taken into account and reinforcement is selected according to the negative design values. You can check the following links on the subject.

Hello, Mr. Levent, first of all, thank you for your interest. I will analyze the project taking into account what you have said. '''''''In the TBDY 2018 regulation, column reinforcements are added in the middle region. For this reason, while the column is being reinforced, the design effects of the lower end of an upper floor and the upper end of the existing floor are taken into account and the reinforcement is selected according to the negative design values.'''' Is there anything you can suggest to minimize this situation. At least in the design phase, I think it would be healthier than architectural and static pain. Thank you again.
