Hello Mr. Serky; First of all, I would like to state that in many seminars and course programs that I have attended recently, our instructors said that the revision work on the Earthquake Regulation has started and that this work will also cover Chapter 7. We hope that this study will be a solution to such problems and will be concluded as soon as possible. In addition, as someone who encounters performance analysis a lot; I would like to say that I have come across very few projects that are trouble-free in normal analysis and cause problems in performance, especially for residential buildings. If you add your project to the forum, we will have a chance to evaluate it. Maybe you will be able to overcome the problem with very small interventions. As Levent said in the brain, there are differences between the two analysis methods, these are the problems encountered. Best regards.
