摘　　要：将能力谱方法应用于桥墩横向和纵向抗震性能的分析,研究在特定场地条件下不同地震烈度对桥梁抗震能力的影响,结果表明:地震烈度越大,其抗震需求越大,性能点的位移也逐渐增大,总体趋势是地震反应由弹性进入塑性。The result of application of the capacity spectrum method to the study of pier transverse and lengthways seismic performance, and study the influence of different design earthquake intensity to the seismic capacity at the invariable ground condition indicates that the seismic demand and the displacement of the performance point are increasing along with the increasing of the earthquake intensity, and the total response trend is from elastic to plastic.

关 键 词：能力谱方法 地震烈度 抗震性能 性能点
