WebThe rigidity of the diaphragms is classified into two groups on relative flexibility: rigid and flexible diaphragm. Flexible vs. Rigid Diaphragms(another definition) The purpose of determining whether a diaphragm is flexible or rigid is to determine whether a diaphragm should have the loads proportioned according to the tributary area WebMay 17, 2010 · It is more intended to contrain groups of nodes for lateral displacement, say to represent a rigid diaphragm, where you have not modeled plate elements. It works well for floor systems, where you have only modeled the floor beams (slab not modeled), to keep all the floor framing retrained to the same displacement. http://eng.sut.ac.th/ce/oldce/CourseOnline/430463/STAAD/AdvTraining/T09%20Floor%20Diaphragm.pdf dbhds discharge summary

This leads to an absence of axial, shear, and moment forces within the diaphragm. An example of a rigid diaphragm in practice could be a reinforced concrete slab, where the bending in-plane is negligible. dbhds direct support training
