What is required to build a pole barn?
Pole barns (post-built structures) look simple at a glance. However, in terms of structural design for wind, snow and seismic forces, they are much more complex than a conventionally build structure such as a stick-built home. In addition, the prescriptive codes (Residential) tell how to frame conventional structures. Structures other than prescriptive are required to be designed per the Oregon Structural Specialty Code. The design, which is required to be done by an Oregon Licensed Engineer or Architect, is done on a case-specific basis for the loads and parameters of the structure.
