在试验研究的基础上,分析了自攻螺钉连接中、薄厚度钢板时双面受剪与单面受剪的破坏过程及破坏形式。同时利用试验数据,经过分析回归,得到单个自攻螺钉连接中、薄厚度钢板的抗剪承载力设计值的计算方法,并给出了自攻螺钉受剪连接的相关构造要求与施工要求建议。
Based on the experimental study, the failure process and failure mode of double-sided shearing and single-sided shearing in the process of self-tapping screw connection and thin-thickness steel plate are analyzed. At the same time, by using the experimental data, through the analysis and regression, the calculation method of the shear capacity of the thin-thickness steel plate in a single self-tapping screw connection is obtained, and the related construction requirements and construction requirements of the self-tapping screw shear connection are given.
