Abstract

This paper investigated the tensile behavior of metal-plate connected Dahurian larch (Larix gmelini (Rupr.) Rupr) lumber joints. Relationships between the ultimate load and metal-plate connector (MPC) length, width, and area were analyzed for AA loading (i.e. load parallel to the grain, MPC length parallel to the load direction) and EA loading (i.e. load parallel to the grain, MPC length orthogonal to the load direction). Failure modes were studies for both AA and AE loading conditions. It was found that the tensile strength of the joint increased as the size of the connector increased. Tooth withdrawals, MPC breakage and wood breakage were all failure modes observed for the AA loading case. However, tooth withdrawal was the only failure mode observed in the EA loading case.
