摘　　要：腹板嵌入式压型钢板组合梁是在腹板嵌入式组合梁的基础上增加压型钢板后形成的一种新型组合梁,由于压型钢板的存在,剪力连接件的抗剪性能可能会发生一定的改变。通过对12个推出试件进行试验,研究了腹板嵌入式压型钢板组合梁中剪力连接件抗剪承载力的特性,并通过参数回归方法拟合出了剪力连接件抗剪承载力的计算公式。试验结果表明:腹板嵌入式压型钢板组合梁的剪力连接件抗剪承载力随着齿口高度、混凝土强度等级的增加而提高;压型钢板对剪力连接件的抗剪承载力有一定程度的降低。The composite beam of webs and profiled steel plates is a new type of composite beam formed by adding profiled steel plates to the embedded composite beam.Due to the presence of the profiled steel plates,the shear resistance of the shear connector may change. The characteristics of shear bearing capacity of shear connectors in composite beams of webs and profiled steel plates were studied by running the pull-out tests on 12 specimens,and the formula for calculating the shear capacity was fitted by the parametric regression method.The results indicate that the shear bearing capacity increases with the increase of the tooth height and the strength grade of concrete;the profiled steel plates cause a certain degree of reduction in the shear bearing capacity of the shear connectors.
