Durability  When put to the test, post-frame buildings consistently outperform other structures. Hurricane Katrina in 2005 provided a recent example. Many non-post-frame structures lay in ruins while properly engineered post-frame buildings remained standing tall amidst the rubble.

The post-frame building system has several key advantages, and these have only improved over time with the evolution of construction technologies and improvements in building components.

What Makes Post Frame So Durable?

1. Post-frame structure forms a tremendously strong box that resists wind and seismic forces.

   Outstanding structural performance of post-frame buildings under adverse conditions, such as hurricanes, is well-documented. Professor German Gurfinkel, in his textbook titled Wood Engineering, cites superior performance of post-frame buildings over conventional construction during Hurricane Camille.Since post-frame buildings are relatively lightweight and benefit from diaphragm action, they efficiently resist wind and seismic forces. Scientific research verified post-frame buildings constructed according to engineered plans generally withstood Hurricane Hugo (wind gusts measured at 109 mph).

2. Post frame’s diaphragm action efficiently uses materials to resist lateral forces, for an effective and inexpensive bracing system.

   Post-frame buildings benefit from the unique properties of diaphragm action. A building diaphragm is a structural assembly comprised of structural sheathing (e.g., plywood or metal cladding) fastened to the framing in such a manner that the entire assembly is capable of transferring in-plane shear forces. These building components work together more efficiently to increase strength and resiliency.

3. Posts in the ground add to a building’s stability and wind resistance.

   Although the posts in commercial post-frame buildings are typically attached to a concrete slab or masonry wall above grade, in certain applications post-frame buildings use posts embedded deep into the ground. This provides an efficient load path directly to the ground. Building with posts offers greater structural stability with fewer materials and the capacity to build a much higher sidewall than conventional wood-framed construction.

4. Post frame provides a lasting foundation.

   Some people mistakenly think that all post-frame buildings use wooden posts in the ground. This is not the case, especially with commercial post-frame buildings. These are almost always on concrete slabs, poured in place foundations or masonry walls. Concrete columns are also an option. However, treated wood posts can be a long-lasting economical option. Post-frame columns/posts typically use the highest level of chemical treatment available. This provides longevity that is far superior to the treated wood found at most home improvement warehouse
