Hello there; tbdy item 3.3.1.1.b does not provide a rigid basement condition and the error is "Increase the system rigidity with high relative floor drift on the 1st and 2nd floors" I increased the screen sizes, I increased the column sizes, but I still couldn't solve it. I would be glad if you can help. I couldn't upload it because the file is big, I wonder what could be the problem. What are the reasons?
 
Re: TBDY 3.3.1.1.b Rigid basement condition and relative storey offset Hello, If the rigid basement does not meet the condition, you should not select it as a rigid basement. You can find detailed explanation from the link below.

. The relative storey drift problem is a stiffness problem that concerns the entire structure . In the relative story displacement report, the name of the element that reaches the highest values in the story and the offset limit value information are given. The probability of solving the problem is low by increasing only one element size. It is appropriate to evaluate the system rigidity throughout the structure. I suggest you to review the links given below about the relative floor drift control and possible solutions.
