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 the cross-joints of waste glass-reinforced concrete beam and column, finite element software ABAQUS was used to establish six nodes of glass-reinforced concrete beam-columns under low cyclic loading by changing parameters such as replacement rate of glass waste, Model, the hysteresis curve, the skeleton curve and the ductility coefficient of the node components were obtained, and the stress conditions and failure modes of the nodes were observed.The results show that under the low cyclic loading of the beam ends, the bearing capacity of the abandoned glass- The strength and ductility tended to decrease compared with that of ordinary concrete, but the value of the decrease was small, which was similar to that of ordinary concrete beam-column joints.
