Demonstration of wind load design for timber frame structures using diaphragm action

Current design procedures for timber frame structures that are enclosed by structural-insulated panels (SIPs) do not typically accommodate the contribution made by the SIPs in resisting lateral loads. However post-frame building design procedures do include the diaphragm action of the metal cladding that encloses them, lending to more efficient structures, This investigation draws parallels between timber frame and post-frame structural systems and elucidates the appropriateness of the post-frame diaphragm design methods for contemporary timber frame buildings. A sample timber frame diaphragm design is performed and the parameters needed to effectively complete the design are identified.
