摘　　要：根据欧洲钢结构设计规范的EN1993-1-8∶2005和GB50017-2003《钢结构设计规范》及JGJ82-2011《钢结构高强螺栓连接技术规程》对单个螺栓的设计承载力进行比较,包括抗剪连接、抗拉连接、剪拉连接和抗滑移连接的单栓承载力。比较分析可知:国标与欧标钢结构设计规范中的抗剪螺栓连接承载力二者基本一致;欧标的高强螺栓预拉力取值比中国的约高10%;抗拉螺栓连接与剪拉螺栓连接主要区别在于螺栓的抗拉承载力如何考虑撬力的影响。According to European standard Eurocode 3 （EC3） ： Design of Steel Structures Part 1-8： Design of Joints（EN 1993-1-8：2005）, Code for Design of Steel Structures （GB 50017-2003） and Chinese Technical Specification for High Strength Bolt Connections of Steel Structures （JGJ 82-2011）, the design resistance of individual bolts was contrasted in the design process, including shear resistance, tension resistance, combined shear and tension resistance, slip resistance and so on. It was found by the comparison results that the shear resistances of bolts in two codes were basically the same. The preload of high strength bolt in Eurocode 3 was about 10% higher than Chinese steel structures code. The main differences of tension resistances of bolts between EC3 and GB 50017-2003 were how to consider the influence of the prying forces.
