摘　　要：文中利用abaqus对采用新型不抗剪开孔钢板抗拔连接件的叠合板组合楼盖边柱节点进行有限元研究分析,并将有限元计算结果与试验结果和栓钉连接件的节点模拟结果进行对比。结果表明,有限元模型能较好的模拟试验情况,试验的破化形态与有限元分析基本一致,对比栓钉节点模拟结果,可以知道采用此新型不抗剪开孔钢板抗拔连接件可以有效的减缓负弯矩区混凝土开裂。后续可以在此模型的基础上开展进一步的研究分析。In this paper,the ABAQUSsoftware is used to conduct finite element analysis on the edge joints of laminated slab composite floor slabs with a new type of anti-pull but non-shear-resistant steel plate connector.The results of numerical simulation and experimental of the joints with the bolt connector are compared.It shows that the finite element model can simulate the test situation well,and the degradation of the test is basically consistent with the finite element analysis.Comparing the simulation results of the stud node,it can be known that using this new type of anti-pull but non-shear resistant steel plate connector can effectively slowdown concrete cracking in the negative moment zone.Further research and analysis can be carried out on the basis of the proposedmodel.
