Nowadays, conventional shear connectors used in the composite slab with steel deck are welded headed shear studs. If the structure reaches the end of its design life, repairing these connectors will cost a lot and cause significant environmental damage. In this paper, with a numerical study, welded shear stud connectors were replaced with new bolted shear ones and the effects of parameters, such as: concrete strength, different positions, heights and diameters of the shear connectors, and the type and thickness of the steel deck, as well as the effect of the reinforcement arrangement on the behavior of these connectors, are evaluated. Moreover, various failure modes are investigated and the results are compared to AISC equations provided for welded shear connectors, to calculate the shear capacity of new bolted connectors. The results show that these connectors could be a good alternative to welded shear studs.

如今，用于带钢甲板的复合板的传统抗剪连接器是焊接式抗剪螺柱。如果该结构达到其设计寿命，则维修这些连接器将耗费大量成本，并会严重破坏环境。本文通过数值研究，将焊接剪力螺柱连接器替换为新的螺栓剪力连接器，并考虑了参数的影响，例如：混凝土强度，不同位置，剪力连接器的高度和直径，以及剪力连接器的类型和厚度评估了钢甲板，以及钢筋布置对这些连接器性能的影响。此外，研究了各种失效模式，并将结果与​​焊接剪切连接器提供的AISC方程进行了比较，以计算新的螺栓连接器的剪切能力。
