摘要
对一榀异形柱框架进行低周反复荷载试验研究,介绍了试验情况,对试件破坏过程及结果进行了描述,给出了荷载-位移曲线及骨架曲线;并基于框架试验数据,分析了模型的试验滞回特性,评估了框架的抗震性能,建立了框架的恢复力模型.得出如下结论:钢筋混凝土异形柱框架结构具有较好的滞回特性,变形特性介于剪力墙结构和普通框架结构之间;框架整体受力分析可采用退化三线型恢复力模型.
Based on the low-cycle repeated loading test of a three-storey RC frame with special-shaped columns,this paper describes the failure procedure and results in detail.The load-displacement curves and skeleton curves are given.The hysteretic relations between the measured horizontal load and the top storey drift are analysed.At last,this paper gives a restoring force model of the frame with special-shaped columns.The behavior of the model subjected to earthquakes offers the basis for the earthquake resistant design and analysis of special-shaped column.
