摘　　要：为了研究屈曲约束支撑混凝土框架梁节点的承载力及延性性能,该文设计了型钢节点板和栓钉节点板两种连接形式的节点。通过ABAQUS有限元分析软件对两种屈曲约束支撑混凝土框架梁节点进行分析,得出在两种不同加载方式作用下的荷载-位移曲线,比较两种节点的极限承载力和延性性能,并分析模型的破坏方式和受力机理,为工程应用提供相应参考。In order to study the bearing capacity and ductility of the joints in a buckling restrained brace concrete frame （BRBCF）, two different types of joints are designed, including the joint with a section steel gusset plate and the joint with a stud gusset plate. The finite element analysis software of ABAQUS is adopted to analyze the performance of the two joints and calculate the force-displacement curves through two different loading modes. The ultimate bearing capacities and the ductility of the joints are compared. Then failure modes and transferring mechanism are analyzed to provide a relative reference for the engineering application.
