Large retail buildings and warehouses are typically a one-story concrete or masonry walled structure with a panelized wood roof. These buildings fall under the category of “RWFD”, or “Rigid Wall Flexible Diaphragm”. There are two preexisting methods that can be utilized in designing flexible diaphragms, but there is a third being introduced in the new ASCE 7-22 code. Given this code is unreleased, there really is no guidance to the user as far as which method is the most time efficient or cost effective. The purpose of this project is to analyze the same building using each design method in ASCE 7-22 and determine or estimate which approach is appropriate.
