摘要
通过 １８很冷轧带肋箍筋柱的试验研究，分析了轴压比、箍筋强度、箍筋间距、体积配箍率等因素对构件延性的影响，提出了适用于各种破坏形态的构件延性评估的新方法。并提出了在不同抗震设计等级下，不同轴压比情况下配箍率的建议值。
Based on experimental research of 18 columns with cold-rolled ribbed stirrups, the analysis of axial load ratio, stirrup strength, spacing and stirrup volume ratio effects to the columns' ductility are carried out. A new method which can estimate the columns' ductility of different damaged pattern is proposed. Authors also give a suggestion for the stirrups ratio under difference seismic grade and axial load ratio.
