摘　　要：本文基于推出试件与组合梁的Abaqus有限元模型,探究橡胶套栓钉群的抗剪性能及布置方法,提出橡胶套分层变尺寸布置下的栓钉群抗剪承载力计算公式.研究结果表明:在栓钉群外层设置较大尺寸橡胶套、在中层和内层设置较小尺寸橡胶套的设计思路较为可行,采用橡胶套变尺寸布置的栓钉群抗剪承载力提升了8.0%,组合梁抗弯承载力提升了4.3%,均取得较好的应用效果;所提出的橡胶套分层变尺寸布置的抗剪承载力计算公式与模拟数据较吻合,误差在±5%以内.Based on the Abaqus finite element model of specimen and composite beam,the shear performance and arrangement method of rubber sleeve bolts were explored,and the calculation formula of shear bearing capacity of rubber sleeve bolts with layered and variable size arrangement was put forward.The research results show that it is feasible to set a larger rubber sleeve on the outer layer of the stud group and a smaller rubber sleeve on the middle layer and the inner layer.The shear bearing capacity of the stud group and the bending bearing capacity of the composite beam increased by 8.0%and 4.3%,respectively,which achieved good application results.The formula for calculating the shear bearing capacity of rubber sleeves with layered and variable size arrangement is in good agreement with the simulation data,and the error is within 5%.
