针对屈曲约束支撑与钢筋混凝土结构梁柱连接节点的受力复杂、强度和刚度影响因素多等问题,该文设计了一种新型的角钢式连接节点。通过对节点进行有限元模拟,分析节点在单调及往复位移载荷作用下荷载-位移曲线、骨架曲线以及预埋件对节点各部件的影响作用,研究其力学性能以及传力机理。结果表明:节点的构造形式合理,传力机理明确,在单调与往复载荷作用下表现出良好的工作性能。 Aiming to the problems that the joint force between the restrained restraint brace and the beam-column connection of reinforced concrete structure is complex and the factors of strength and stiffness are numerous, a new type of angle steel joint is designed. Through the finite element simulation of the nodes, the influence of load-displacement curve, skeleton curve and embedded parts on the components of the joints under monotonous and reciprocating displacement loads are analyzed, and the mechanical properties and force transmission mechanism are studied. The results show that the node has a reasonable structure, a clear mechanism of force transmission, and a good working performance under monotonous and reciprocating loads.
