In order to obtain the ratios of static-to-fatigue moment capacity, the fatigue performance of T-shaped, end-to-side gusset- plate joints made of oriented strandboard (OSB) was investigated. A total of 108 stapled and glued-stapled joints with gusset- plates of different lengths (6, 8, and 10 in) were subjected to one-side cyclic stepped bending loads. Test results showed that assemblies with OSB gusset-plates would fail within 25,000 cycles when a stepped load level exceeded 63 percent of their static moment capacity. The passing static-to-fatigue ratio averaged 2.1 with the COV of 12 percent. In the stapled joints, the higher ratios were associated with the staple withdrawal as dominating failure mode. In the glued-stapled joints, lower ratios were associated with in-plane shear and the higher ratios with the rupture of the OSB panels.
