March 28, 2019 -- Chicago, IL -- In collaboration with the Natural Resources Conservation Service, the National Frame Building Association ( NFBA) has published its Non-Diaphragm Post-Frame Building Design Guide in both electronic and print formats.
A diaphragm is an element that distributes structural loads throughout a building. It uses exterior cladding (usually metal in the case of post frame construction) to transfer the load evenly to the structure and into the foundation. With no diaphragm, each element or building frame must transfer the load directly.
Non-diaphragm buildings typically have open sides for easy access to, for instance, large agricultural equipment, or salt used on winter roads. Structures in public parks are another example.
"While these structures look simple, the absence of diaphragms can make designing them a bit tricky," says Andy Williams, NFBA's Director of Technical Support. "This guide will be extremely helpful."
The new guide provides a comprehensive overview of the structural design process for non-diaphragm post frame buildings. It covers the use of posts, knee braces, metal cables and other elements used to support these buildings. The guide can be purchased at nfba.org/resources/technical, with favorable pricing for NFBA members.
National Frame Building Association (NFBA) is a nonprofit trade association that promotes the interests of the post-frame construction industry and its members. The association’s members are primarily post-frame builders, suppliers, manufacturers, building material dealers, code and design professionals, and structural engineers.
NFBA is the only national trade association that represents post-frame industry professionals. The association exists to support its members and stimulate the growth of the post-frame industry by providing industry tools and code resources, education, access to technical and legal experts, builder accreditation programs, newsletters and post-frame market development updates, and networking opportunities.
Currently, there are approximately 800 NFBA member companies across the United States.
