摘　　要：针对定向刨花板水平和垂直纹理会对冷弯薄壁型钢C型骨架柱连接力学性能产生影响的问题,进行了10个定向刨花板与冷弯薄壁型钢C型骨架柱静力拉伸试验,分析了定向刨花板的水平、垂直纹理对破坏形式、连接刚度及极限承载力的影响.结果表明:垂直纹理试件呈现纤维撕裂破坏,承载力比水平纹理试件高约10%;水平纹理试件为木质纤维剪切破坏,连接刚度比垂直纹理试件高约8%.试验为冷弯薄壁型钢-定向板结构设计提供了设计参考.In order to solve the problem that the horizontal and vertical texture of oriented strand board （OSB） will affect the mechanical connection performance of cold-formed thin-walled C-type steel column, the static tensile tests for 10 OSB and cold-formed thin-wall C-type steel column were carried out, and the influence of horizontal and vertical texture of OSB on the failure mode, connection stiffness and ultimate load capacity was analyzed. The results show that the specimen with vertical texture exhibits the fiber fracture damage, and the load capacity is about 10% higher than that of the specimen with horizontal texture. In addition, the specimen with horizontal texture exhibits the wooden fiber shear failure, and the connection stiffness is about 8 % higher than that of the specimen with vertical texture. The tests can provide the design reference for the cold-formed thin-wall steel-OSB structures.
