摘　　要：基于延性设计理论分别用反应谱法、刚度折减的反应谱法和时程分析法对城市规则桥梁双柱墩进行地震反应分析,并选用刚度折减的反应谱法进行了抗震验算,提出了双柱墩地震反应分析方法的优化建议,以供参考.The response spectrum method,stiffness reduction of response spectrum method and time history analysis method are used to analyze seismic response of urban regular bridge ＇s double column piers based on ductility design theory,and the stiffness reduction of response spectrum method is used to carry out seismic checking also,and the optimal advice of double column piers＇ seismic response analysis method is put forward for your reference in the paper.

关 键 词：延性设计 能力保护 刚度折减 反应谱 PUSHOVER方法 时程分析
