摘　　要：为研究废弃玻璃混凝土梁柱十字节点的抗震性能,采用有限元软件ABAQUS,通过改变废弃玻璃替代率、节点配箍率等参数,建立6个在低周反复载荷作用下废弃玻璃混凝土梁柱节点的模型,得到了节点构件的滞回曲线及骨架曲线、延性系数等,观察节点的受力情况、破坏形态.研究结果表明:在梁端低周反复载荷作用下,废弃玻璃混凝土梁柱节点的承载力、延性性能较普通混凝土出现降低的趋势,但降低的数值很小,与普通混凝土梁柱节点的抗震性能基本相似.In order to study the seismic performance of waste glass concrete beams cross nodes, this paper established 6 models of waste glass concrete beam-column joints under low reversed cyclic loading with finite element software ABAQUS by changing the waste glass replacement rate, node parameters such as band ratio, obtained the hysteretic curve and skeleton curve of the node components, etc., and observed the node stress distribution and failure pattern. The results of study show that on the beam end under low reversed cyclic loading, the bearing capacity of the waste glass reinforced concrete beam-column joints appears lower than that of normal concrete, but the amount of reducing is small, similar to the seismic resistance of ordinary concrete base.
