摘　　要：在现有钢框架建筑结构体系中,梁柱节点作为传力枢纽是钢框架结构中重要的一部分。不同于传统的焊接方式,本文采用现场装配式方法将方钢管柱和H型钢梁通过端板用高强螺栓栓接在一起。利用ABAQUS有限元模拟分析与低周往复荷载试验,通过对节点的破坏特征、骨架曲线、耗能能力和初始刚度等力学特性进行分析,研究了该节点的抗震性能。分析结果表明,增大梁柱截面尺寸、加长梁端板、增加贴板,节点承载力增高、初始刚度增强、刚度和强度退化稳定、节点耗能能力和抗震能力增强。In the existing steel frame building structure system,the beam-column joint is an important part of the steel frame structure as a force transmission hub,which is different from the traditional welding method.This article uses the field assembly method to pass the square steel pipe column and the H-shaped steel beam through the end the boards are bolted together with high-strength bolts.Using ABAQUS finite element simulation analysis and low-cycle reciprocating load test,through the analysis of the failure characteristics,skeleton curve,energy dissipation capacity and initial stiffness and other mechanical characteristics of the node,the seismic performance of the node is studied.The analysis results show that increasing the beam-column section size,lengthening the beam end plate,and increasing the veneer,the joint bearing capacity is increased,the initial stiffness is enhanced,the stiffness and strength are degraded and stabilized,and the joint energy dissipation capacity and seismic resistance are enhanced.
