摘　　要：为研究新型胶结混合抗剪键的受力性能,文中针对预留孔径参数结合推出试验采用ABAQUS有限元分析软件对新型胶结混合抗剪键进行非线性分析,将试验结果与有限元分析结果进行对比。结果表明,文中有限元模型能较为合理地模拟试验结果;同时,试件前期刚度与受剪承载能力及栓钉抗弯性能受预留孔径参数影响;最后给出预留孔径参数建议,为实际工程提供相关设计参考。In order to study the mechanical performance of the new shear connectors by epoxy mortar mixed bonding,the Abaqus finite element analysis software is used in conjunction with the launch test to perform nonlinear analysis of the new shear connectors by epoxy mortar mixed bonding for the reserved aperture parameters in this paper.The test results are compared with the results of finite element analysis.The results show that the finite element model presented can reasonably simulate the test results.Through the finite element analysis method,it is concluded that the early stiffness of the specimen,the shear bearing capacity and the stud flexural performance are affected by the reserved aperture parameters;finally,suggestions are given on reserved aperture parameters to provide relevant design references for practical projects.
