    The important role of boundary conditions in tests of compression members was evaluated when determining the instability loads of asymmetric and nonprismatic compression webs for wood trusses. The compression webs were created by nailing a side member to the truss web so that the cross section was L-shaped. In the analytical investigation, the side members were assumed to be as long as the truss web, and the boundary conditions were for pinned and elastically restrained connections. In the experiments, L-reinforced webs were tested with pinned and metal-plate-connected boundary conditions and with side members of various lengths. The boundary conditions had a significant effect on stability load and the failure mode. Capacity of the L-reinforced truss web may be governed by the metal connector plate rather than wood strength or instability.
