摘　　要：基于新型石膏混凝土复合墙板L型节点低周反复荷载试验的结果,针对墙板连接处L型节点的构造形式,通过有限元计算分析其抗震性能,以确定性能更好的连接形式。分别建立了横向钢筋贯穿整个节点核心区和横向钢筋不伸入节点核心区的L型墙板有限元模型,对比分析二者的承载能力、破坏特征、滞回特性、延性系数、耗能性能以及刚度退化,得到横向钢筋伸入节点核心区的墙板连接形式的抗震性能要优于横向钢筋不伸入节点核心区的墙板节点形式。Based on the results of the low cyclic loading test of the L-shaped joint of the new gypsum concrete composite wall,analyzed the seismic performance of the L-shaped wall joint by finite element method to determine the better connection form. Created the finite element model of L-shaped wall with horizontal steel bar extending through the core and the horizontal steel bar didn＇t extend into the core area to analyze their loading capacity,failure characteristics,hysteretic behavior,ductility coefficient,energy dissipation performance and stiffness degradation. The seismic performance of the connection form of the horizontal steel bar extending into the core section of the joint is better than that of the horizontal steel bar without extending into the core section of the joint.
