摘　　要：某新型多层预拼装钢结构系统采用了钢板自攻螺纹螺栓连接形式,超出现行规范中连接类型,需进行相关试验进行论证,针对工程常用6种规格高强螺栓自攻螺纹连接进行了单个螺栓抗剪试验,研究了此种连接的抗剪破坏模式,并依据摩擦型高强螺栓及承压型高强螺栓不同的设计假定确定两种情况下的极限承载力,与规范要求承载力设计值进行比对,为该种新型螺栓连接提供设计依据。A new kind of bolt connection consisted of self-tapping steel plate and high strength bolt will be used in a multistory fabricated steel structure system .But there are no regulations on such kind of bolted con-nection .Therefore ,extensive experimental research on bolted connection was taken .The objective of the re-search was to determine the ductility and resistance of such connection .The failure mode of bolted connections could be observed in the test .The ultimate bearing capacities of friction type high-strength bolt and bearing type high-strength bolt are different due to different design provisions and both bearing capacities were dotained in this experiment .The ultimate bearing capacities were compared with that predicted by the current connec-tion provisions specified in china steel design standards .
