- This study evaluated the fatigue performance of T-shaped, end-to-side, metal-plated joints made of 18-mm (23/32-in) structural oriented strandboard (OSB) to obtain the static-to- fatigue moment capacity ratios. A total of 80 joints with metal plates of different configurations were subjected to one-side cyclic stepped bending loads. Test results showed that assem- blies with OSB metal-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 ratios aver- aged 2.5 with a COV of 22 percent. In all metal-plated joints, the dominating failure mode was metal-plate yield; the rest was shear-out of OSB.

- 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.

- Power-driven staples are commonly used to join framing members in upholstered furniture construction because of their quick and easy installation. To successfully introduce oriented strandboard (OSB) into upholstered furniture as frame stock, moment capacity data for stapled gusset-plate joints constructed of OSB are needed. In this study, the static moment capacity of T-shaped, end-to-side joints with two gusset-plates was determined experimentally and analytically for gusset-plates of different lengths (4, 6, 8, 10, and 12 inches) attached with 1.0-inch- and 1.5-inch-long staples with and without adhesive. The moment capacity of the joint increased in proportion with the length of the gusset-plate until the strength of the gusset exceeded that of the main joint member. Analytical prediction of the moment capacity of an unglued stapled joint was found satisfactory. Ap- plication of glue to the connection surface changed the failure modes of the joints and increased their moment resistance capacity.

- Metal-plate connectors are commonly used to connect critical joints in upholstered furniture frames due to their high load resistance, rapid assembly, and easy connection of members with uniform thickness. To successfully introduce oriented strand- board (OSB) into furniture frames, basic data for metal-plated joints constructed of OSB is needed. In this study, static moment capacity of T-shaped joints with metal-plates was determined experimentally for different configurations. The moment capacity and stiffness of the joint with one pair of metal-plates increased in proportion with the width of the metal-plate up to 6-in (152 mm). When the metal-plate was equal the full width of the OSB member, too many teeth cut into it, making the assembly weaker. Metal-plated joints with two pairs of plates were nearly 50 percent stronger and stiffer than those with a single pair of metal-plates covering the same area.
