Hello, even though my attached project is a regular 3-storey simple structure, I am getting system rigidity problem. What is the reason for this and how can I find a solution? Thanks in advance, good work.
 
Earthquake acceleration is very high in ZE soil group. If you select a more solid soil group and enter the acceleration values, you can observe how much the relative floor drift values differ (decrease). You have no choice but to increase the column dimensions in terms of the structure location. You can also consider applying TBDY Article 4.9.1.3b, provided that it is built on site. There is an option in the analysis settings.
