摘　　要：本文在总结以往螺栓剪切刚度试验技术的基础上，设计出一种新的螺栓剪切刚度试验件． 并通过一组同一尺寸单个螺栓连接件的试验，得出一簇刚度曲线（即Ｐ－ δ曲线，Ｐ为剪切力，δ为变形）；通过可靠性分析方法，得出该种连接件螺栓刚度的分布区间，为连接件的可靠性内力分析提供技术基础．A new type of the specimens used for shearing stiffness test of bolts is designed. By employing a group of the specimens in the stiffness test of bolts, a cluster of P-δ curves for bolt fastening is obtained. A distribution interval for the shearing stiffness of the bolts is drawn by reliability analysis, which may serve as a technical foundation for the strength analysis of the bolt fastenings.
