中文摘要：
基于性能的抗震设计于20世纪90年代兴起以来,目前在土木建筑方面的文献较多,但是关于桥梁的研究成果较少。采用五级钢筋混凝土桥墩结构性能水平,以钢筋混凝土桥墩墩顶位移角为量化指标,建立了钢筋混凝土桥墩性能水平与钢筋混凝土桥墩位移角限值之间一一对应的关系。将地震危险性分析与最优设防烈度结合起来,建立基于投资-效益准则的RC桥墩全寿命总造价计算的通用框架。
英文摘要：
Since the proposal of performance based on seismic design theory advocated by American scholars in 1990s , great achievements in structural research area have been made .However ,little attention has been paid to the research on bridges .With the value of the top displacement angle as the index ,a corresponding relationship between the performance level of reinforced concrete （RC ） bridge pier and its limited value of the top displacement angle was established in this paper adopting the five performance levels of RC bridge piers .This method combined the seismic hazard analysis and the optimized seismic fortification intensity ,on which the universal calculation method for the total cost of a RC bridge’s life span based on the investment-benefit criterion was established .
