| 摘 要： | 为研究持有荷载作用对钢筋混凝土节点抗震性能的影响,基于大型有限元软件ABAQUS建立了钢筋混凝土节点的抗震性能分析模型,并对其进行了数值分析。结果表明,持有荷载比、柱截面含钢率、柱箍筋加密区体积配箍率、混凝土强度等级、梁柱线刚度比对持有荷载作用下钢筋混凝土节点抗震性能影响显著,钢筋强度等级对持有荷载作用下钢筋混凝土节点抗震性能影响不大。

| Abstract: | In order to study the influence of holding load on the reinforced concrete joint seismic performance,establish the reinforced concrete joint seismic performance analytic model based on the finite element software ABAQUS and conduct numerical calculation and parameter analysis of reinforced concrete joint seismic performance under the function of holding load.The results show that the holding load ratio,column section steel ratio,volume-stirrup ratio of column stirrup intensive zone,concrete strength grade and beam-column line stiffness ratio have great influence on the reinforced concrete joint seismic performance under the function of holding load,steel bar strength grade has little influence on the reinforced concrete joint seismic performance under the function of holding load. |
