摘要：为探究国产规格材在齿板连接性能方面存在的优劣势,完善国产结构材体系。笔者对两种国产规格材齿板连接节点的板齿极限承载力、临界刚度、破坏形式进行了研究。结果表明:不同种类木材顺纹抗拉强度差异性显著,两种国产落叶松齿板节点板齿极限承载力、临界滑移刚度、峰值区域面积均高于北美云杉。
In order to explore the tensile property of domestic larch lumber and improve the domestic light wood frame construction,the ultimate load carrying capacity, critical slip stiffness and failure forms in tensile process of the truss plate joint were tested.The results showed that the tensile strength parallel to grain of difference species has significant differences.The ultimate load carrying capacity, critical slip stiffness and peak area of domestic larch dimension lumber were higher than Picea sitchensis.
