Fast forward to the late 70smid 80s: post-frame structures evolved into a finely-tuned engineered building system.Development and documentation ofdiaphragmdesignmethodologiesinthe 1980stomid1990simprovedthestructural efficiencyofpost-framebuildingsystemsand launchedtheadoptionofpost-frameintothe commercialandresidentialbuildingsectors.Post-frame accommodates a variety of foundation options, including concrete walls, concrete piers, thickened edges of concrete slabs and other products.Post-frame buildings are exceptionally resistant towind,snow,andseismicloads.Theentire structure works as a diaphragm to provide superior lateralload-resistanceproperties.Ifadesign professional does not account for the diaphragm actionprovidedbypost-framebuildings,heor she may significantly over-engineer the building. Engineers who may not be familiar with how to account for diaphragm action may also mistakenly conclude that a post-frame building will not meet prescribed load criteria.
