Post-frame buildings consistently outperform many other structures, particularly in the area of durability. When compared to other wood-framed construction, post-frame systems provide greater structural stability and also the capacity to build a much higher sidewall with fewer materials. The posts in most post-frame buildings are either embedded directly into the ground or are attached directly to the top of cast-in-place or precast embedded concrete piers. Posts may also be attached to continuous concrete or masonry foundation walls or to thickened edges of concrete floor slabs above grade. Portions of posts embedded directly in the ground must be properly pressure preservative treated. Any of these post-foundation options transfer lateral loads efficiently and directly to the ground and add to a building’s stability and wind resistance.
Post-frame buildings are relatively lightweight and perform exceptionally well under adverse conditions. The diaphragm design procedures used in post-frame building account for how all of the building components work together to transfer lateral loads to the foundation. This makes these structures highly resilient under the pressure of external stresses such as design wind, snow, and seismic loads.
