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.

用近表面安装的胶棒预加固榫眼接头

这篇论文报道了预加固对榫眼接头的影响，该榫眼安装在榫眼表面附近，带有胶合杆。在单调载荷下测试了15个用工程木产品使用计算机数控技术制造的满量程标本。从已建立的力矩-旋转角关系中获得了具有不同钢筋配置的节点的初始刚度和承载力。从测试中发现，加固榫眼榫的初始刚度增加了2.9％，达到30.8％，力矩承载力增加了13.6％，达到32.0％。数值模拟得出的进一步结论包括：增加棒的包埋长度和直径，以及棒的钢强度和减少到表面的距离，可以帮助提高接头的初始刚度和承载力。力矩和初始刚度随榫的高宽比的增加而降低。通过选择适当的参数，建议的预加固方法显着提高了初始刚度和承载力。这项研究证明了通过近表面安装的胶合棒在新的木材结构中预加固榫眼榫接缝的可行性，对于促进榫眼榫接缝在现代木结构中的广泛应用具有重要意义。力矩和初始刚度随榫的高宽比的增加而降低。通过选择适当的参数，建议的预加固方法显着提高了初始刚度和承载力。这项研究证明了通过近表面安装的胶合棒在新的木材结构中预加固榫眼榫接缝的可行性，对于促进榫眼榫接缝在现代木结构中的广泛应用具有重要意义。力矩和初始刚度随榫的高宽比的增加而降低。通过选择适当的参数，建议的预加固方法显着提高了初始刚度和承载力。这项研究证明了通过近表面安装的胶合棒在新的木材结构中预加固榫眼榫接缝的可行性，对于促进榫眼榫接缝在现代木结构中的广泛应用具有重要意义。
