【摘要】 完成了3个高轴压比下扁柱试件在反复荷载作用下的试验。讨论了其破坏形态及滞回特性,并分析 了轴压比、箍筋形式及配箍率等因素对试件延性的影响。结果表明采用普通矩形箍筋柱的延性较差,采用带 十字拉筋的矩形箍筋柱的延性稍好,采用井字箍筋柱的延性较好。研究结果可为进一步了解框架扁柱的抗震 性能提供依据。更多还原

【Abstract】 Three specimens of flat columns with high axial compressive ratio under frequency cyclic loading were tested,the failure process was observed and the failure mechanism of the specimens were studied.The results show that the ductility of flat column with rectangular stirrup is poor, and the ductility increases with the enhancing of the stirrup ratio.The experiments provide basic informations for detecting the seismic behavior of flat columns in frames.更多还原
