The wood arch frame system comprises a plurality of arch-shaped frames, whic h are parallel to each other and separated by specific bay lengths, or radially distributed at specified angles, and in either case are laterally supported by wood purlins, which ar e transversal to the frames. The main purpose is to provide an economical solution for agricultural buildings and is intended for the construction of barrel vaults or round-type buildings that can be covered by fabric, steel cladding, or plywood and shingles. These frames are assembled by interconnecting segments, which are comprised of curved or linear lower and upper chords joined together by a vertical web panel. Chord s are made from wood, usually of the spruce-pine-fir type, and the web panel of plywood or oriented strand board (OSB). Adjacent segments are interconnected using steel straps bolted to the chords and plywood web connectors bolted at both sides of each connection.
