I have a concrete frame in a 5 story building on every floor that is taking the wind force/lateral in E-W direction. The concrete frame consists of 3 concrete columns and a concrete beam. I want to analyze the frame considering the imperfection affects etc. based on EC2. Even though this like a very typical situation, I could not find any examples or references for how to run the analysis based on EC2 on it.
I already modeled it as a 2D frame in Sofiplus, and created the load cases, combinations, linear analysis.
I would be happy if anyone could help me with it. Attached is the model.
