铝合金构件高强螺栓牙板连接性能试验

主要对铝合金构件采用高强螺栓牙板连接进行初步试探性的理论分析和试验研究.分析结果表明:连接承载力与螺栓预压力、板件厚度、牙纹规格等因素有关,并初步得出了承载力的计算公式.进行了4组铝合金构件高强螺栓牙板连接的抗剪承载力试验,试验结果表明:高强螺栓牙板连接具有变形小、承载力高等特点,而且较普通的摩擦型高强螺栓连接承载力有明显提高,主要是因为"牙板"增大了受力方向的抗滑移系数.

Experimental Research on High Strength Bolted Zigzag Plate Connections of Aluminum Alloy Members

This paper focuses on the premature theoretical analysis and experimental research of high strength bolted zigzag plate connections of aluminum alloys. It is found that the factors affecting the bearing capacity of the connection are prestress in boltes, thickness plates and zigzag dimensions. Shear resistant capacity tests were conducted for aluminum alloy component with high strength bolted zigzag plate connections (HSBZP). The test results showed that high strength bolted zigzag plate connections had copious advantages including but not limited to reliable force transferring, comparatively slight deformation and much higher capacity than regular slip critical bolted connections, The zigzag plates increased the slip resistance of the connection.
