Hi I want to know the use of diaphragms in etabs. i discus many people who are use etabs but i can't get justified answer about the application of etabs. I read the Technical reference of Etabs, where they write about Diaphragms. i get two type of diaphragms (plate or shell and joint or beam). My question. 1. When do i use Shell diaphragms (if floor present ) 2.When do i use joint diaphragms ( grade beam level where no slab are provide) NB: Diaphragms use to transfer the lateral load to the resisting element ( frame such as column. beam,shear wall)
