Abstract [en]

Gusset-plate and metal-plated connectors are commonly used in joints of upholstered furniture frames due to their high load resistance. To successfully introduce oriented strandboard (OSB) into furniture frames, basic data on the performance of the joints constructed of OSB members is needed. In this study, out-of-plane static moment capacity and rotational stiffness of T-shaped joints with gusset-plates and metal-plate connectors (MPC) were determined experimentally for different configura- tions. On average, gusset-plate joints exhibited about 80 percent higher out-of-plane static moment capacity than MPC joints. The rotational stiffness of gusset-plate joints without glue was similar to that of MPC joints; however, the stiffness of glued gusset-plate joints was, on average, 70 percent higher. Among MPC joints tested, those with two pairs of 2- by 6-in metal plates showed the highest unit resistance. For gusset-plate joints, an increase in length of the gusset plate from 4 to 8 inches increased the moment capacity for both glued and unglued joints, but a further increase of the length did not result in any significant increase in the strength. It can be concluded that for the studied joint geometry, the 8-in gusset-plate presented the optimum design. Comparisons with previous in-plane bending tests on the joints of the same type and configurations showed that the in-plane moment capacity was 4 to 6 times higher than that out-of-plane.
