摘　　要：设计实践表明，我国现行（钢结构设计规范）［５］关于栓钉和槽钢剪力连接件的抗剪承载力计算公式过于保守，导致设计计算所需要的连接件数量偏多、间距偏小。本文通过４０余根钢－混凝土组合梁试件的试验研究，定量分析了栓钉和槽钢剪力连接件在组合梁中的实际抗剪承载力，得到了现行公式偏于保守的程度，并在此基础上提出放宽对栓钉连接件承载力公式限制条件的建议。It has been shown by design practice that the formulae stipulated In current Chinese Design Speclflcatlon of Steel Structures are too conservative for predicting the shear capacity of stud and channel connectors.Based on the experimental study of more than 40 specimens,quantitative analysis Is conducted on the actual shear capacity of stud and channel connectors In composite beams,and the extent of conservatlveness of the above-mentioned formulae is obtained.Lastly,suggestion Is ProPosed for relaxing restriction on the uPPer limit of shear capacity of stud connectors.
