摘要：This paper reported the effects of the pre-reinforcement to the mortise-tenon joints with glued-in rods that were mounted near the surface of the tenon. Fifteen full-scale specimens that were manufactured with engineered wood products using computer numerically controlled technology were tested under monotonic loading. The initial stiffnesses and moment carrying capacities of joints with different reinforcement configurations were obtained from the established moment-rotational angle relationships. It was found from the tests that the initial stiffness of the reinforced mortise-tenon joints increased by 2.9% to 30.8%, and the moment carrying capacity increased by 13.6% to 32.0%. Further conclusions drawn from the numerical simulation included the following: increasing the embedment length and diameter of rods, as well as the steel strength of rods and decreasing the distance to the surface, could help enhance the initial stiffnesses and moment carrying capacities of the joints. The moment and initial stiffness decreased with increasing of tenon's height to width ratio. By choosing appropriate parameters, the proposed pre-reinforcement methods significantly increased the initial stiffness and moment carrying capacity. This study demonstrated the feasibility of pre-reinforcing mortise-tenon joints in new timber constructions via near-surface-mounted glued-in rods and is meaningful for promoting wider application of mortise-tenon joints in modern timber structures.
