Lateral Load Distribution Using Diaphragm Design

The wind pushes against the exterior sheathing on the windward wall and roof, and pulls on the exterior sheathing on the leeward wall and roof. These forces are transmitted to the columns and trusses by the girts and purlins, the column pushes on the ground at the base and the truss at the top. The horizontal load at the truss is transferred to the endwalls by the roof diaphragm. The roof diaphragm acts like a deep beam constructed of sheathing, purlins, trusses and fasteners. The lateral load at the endwall is transferred to the ground by the endwall diaphragm constructed of sheathing, girts, columns and fasteners. All of these building components act together to provide a stable and long lasting structure.
