新型轻木墙体面板-龙骨节点试验研究

Experimental study on new type of stud-to-sheathing joints in light wood frame wall

以杨木LVL为木龙骨，对不同面板和不同连接方式的4组不同类型的面板-龙骨节点进行单调加载试验，测出其荷载．位移曲线，并对不同类型节点的承载力、变形能力、破坏模式进行比较。结果表明：相比OSB板，杨木胶合板作为节点覆面板时，节点性能更好；在龙骨与面板之间粘结橡胶条可以明显改善节点性能；当橡胶条与钉共同作用时，节点性能得到大幅提高。

Monotonic loading tests were conducted on 4 groups of different types of stud-to-sheathing joints with different panel forms and different ways of connection based on poplar LVL as wood stud. The load-displacement curves were measured and bearing capacity, deformation capacity and failure mode of different types of joints were compared. The results show that the joint performance is better when adopting poplar plywood as panel sheathing; the rubber strip can obviously improve the performance of the joints, and the performance of the joints is greatly improved when the rubber-nail joint is used.
