摘　　要：通过试验分析了钢筋PP ECC柱的抗震性能,钢筋PP ECC柱抗震性能优于普通钢筋混凝土柱,PP ECC柱的抗震耗能随配筋率的增大而提高,纤维掺量和龄期对抗震耗能影响有限。同时通过理论分析和数值计算,计算出钢筋PP ECC柱抗震性能的相关特征参数,得出钢筋PP ECC柱理论骨架曲线模型,通过分析发现与实际值基本接近。The seismic performance of reinforced PP ECC columns is analyzed through tests.The seismic performance of reinforced PP ECC columns is better than that of ordinary reinforced concrete columns.The seismic energy consumption of PP ECC columns increases with the increase of reinforcement ratio,and the influence of fiber content and age on the seismic energy consumption is limited.At the same time,the relevant characteristic parameters of seismic performance of reinforced PP ECC columns are calculated through theoretical analysis and numerical calculation,so as to obtain the theoretical skeleton curve model of reinforced PP ECC columns.It is found that it is basically close to the actual value through analysis.
