摘　　要：结合最新颁布《建筑抗震设计规范》(GB50010—2010)对抗震钢筋的性能要求,从满足构件延性角度对抗震钢筋各性能指标进行了分析,讨论了用不同伸长率指标表征钢筋延性的意义,通过理论分析并结合国外规范对抗震钢筋的性能比较,建议对高强钢筋应考虑屈服平台的延伸率,基于钢筋塑性变形损失,对钢筋的伸长率进行了分级划分。According to the reguirement for seismic steel property in the Code for Seismic Design of Buildings （GB50010--2010） issued recently ,the property indexes of seismic steel analyzed in this paper from the angle of component ductility and then, the sighificance using different elongation inde- xes to characterize the concrete steel ductility is discussed too. After theoretical analysis and compa- ring the property with other countries codes, it is suggested that the elongation of yielding platform should be considered for high-strength steel and the seismic steel elongation should be classified ac- cording to its plastic deformation loss.
