The findings of the research demonstrated the existence of "Group Effect" in the connections including more than one screw, which means that the assumption that the connection strength for a multiple screw connection is proportional to the number of screws in the connection, as the calculation method in Chinese current national standard Technical code of cold-formed thin-walled steel structures have based on, would result in an unconservative estimate for the shear capability of connections including more than one screw.

本文研究结果表明：自攻螺钉连接中存在&群体效应&，我国现行《冷弯薄壁型钢结构技术规范》中相关设计计算方法忽略群体效应，对含多颗螺钉的自攻螺钉连接偏于不安全。
