FNA or Direct Integration method to use in Etabs for pounding ?

19 July 2023 1 5K Report

As part of the pounding analysis comprising a 5-story and a 3-story structure in ETABS, I have introduced gap elements between the buildings. I am currently evaluating which analysis method to employ - FNA or Direct Integration. Which of these methods would be more suitable for this scenario?

Hossein Safar Yousefifard

According to CSI ETABS manual and its advice you have better to use FNA methods because of its speed and accuracy in most of the cases.
