WebJul 1, 2009 · flexible vs rigid diaphragms. Most texts and manuals I've referenced seem to indicate that traditionally wood diaphragms are idealized as being flexible. The lateral analysis for flexible diaphragms is easier than a rigid analysis and can sometimes result in a more conservative design. That being said, when looking through either ASCE 7 or the ... Webcenterlines are zero, and thus rigid constraints can be applied to model a rigid diaphragm (e.g. steel sections, elastic materials) • For nonlinear-beam column elements with RC fiber section where the neutral axis shifts due to bending in the beam axial strains at element’s centerlines are no longer zero. Thus, rigid
