摘　　要：为研究不同轴压比对装配式非对称钢梁-钢管柱连接节点抗震性能的影响,文中利用ABAQUS对其破坏模式、延性及强度退化等进行非线性分析。结果表明装配式非对称钢梁-钢管柱节点的破坏特征均为梁端受弯破坏。非对称外加强环板构造会降低节点的承载力退化性能、延性、耗能能力及强度退化性能。轴压比会对装配式非对称钢梁-钢管柱节点的初始刚度产生较大影响,而对节点承载能力、变形和耗能能力的影响相对较小。To investigate the impact of varying axial compression ratios on the seismic performance of prefabricated asymmetric steel beam-steel tube column joints,this paper conduct a nonlinear analysis of the failure modes of the joints,ductility,and strength degradation by using ABAQUS.The results show that the failure characteristics of prefabricated asymmetric steel beam-steel tube column joints are all bending failures at the beam ends.The asymmetric external reinforced ring plate configuration reduces load-bearing capacity degradation,ductility,energy dissipation capacity,and strength degradation performance.Axial compression ratio significantly affects the initial stiffness of the prefabricated asymmetric steel beam-steel tube column joints,while its effects on load-bearing capacity,deformation,and energy dissipation capacity are relatively minor.
