摘要
提出了一种新型装配式框架结构梁柱节点连接形式,并对其对抗震性能进行研究.基于ABAQUS建立新型梁柱节点模型,输入荷载位移曲线,通过位移加载方式绘制节点在低周往复作用下的滞回曲线及骨架曲线,以混凝土强度等级、螺栓强度等级为变量,研究节点抗震性能.研究表明:随着混凝土强度及螺栓强度提高,梁柱节点的承载力随之提高,等效黏滞阻尼系数及延性位移比现有钢筋混凝土大,新型梁柱节点抗震性能较好.因此装配式混凝土梁柱节点可应用到预制装配式框架结构中.
In this paper,a new type of beam-to-column connection form of assembled frame structure is proposed,and its seismic performance is studied.Based on ABAQUS,a new beam-column joint model is established.The load-displacement curve is input,and the hysteresis curve and skeleton curve of the joint under low-cycle reciprocating action are drawn by displacement loading.The seismic performance of the joint is studied with concrete strength grade and bolt strength grade as variables.The research shows that with the increase of concrete strength and bolt strength,the bearing capacity of beam-column joints increases,the equivalent viscous damping coefficient and ductile displacement are larger than those of existing reinforced concrete,and the new beam-column joint has better seismic performance.Therefore,prefabricated concrete beam-column joints can be applied to prefabricated frame structures.
