(大连市建筑设计研究院有限公司，大连116021)[摘要] 本文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。[关键词] 自攻螺钉; 抗剪连接; 抗剪承载力设计值中图分类号： TU391, TU317 文献标识码： 文章编号：1002-848X(2013)S2-0505-04作者简介：徐海平，学士，48690604@qq.comResearch on shear capacity and design method of self-tapping screw connectingXu Haiping, Liu Nan(Dalian Institute of Architectural Design Co., Ltd., Dalian 116021, China)Abstract: Based on experimental research, the article analyzes the development of shear stress and the failure modes of double-sided and the single-sided self-tapping screw connections under shear stress. In this paper, experimental data together with present data are used to regress a new design method of single self-tapping screw connected moderate and thin thickness steel plates; relevant structure and construction requirements of the self-tapping screw connections in shear are stipulated.Keywords: self-tapping screw; shear connection; design values of shear bearing capacity.
