ABSTRACT
For determining an appropriate retrofitting method for a bridge structure based on economy, this work proposes an annual-expected resilience index for a bridge to simulate the resilience-considered seismic risk that is caused by multiple seismic events in a given period. Along with the direct costs, the resilience-considered indirect costs are also included in the seismic risk and benefit–cost ratio to determine an appropriate retrofitting strategy for a bridge structure. In this work, a bridge in Taipei is used as an example of the application of the proposed quantification method to determine a retrofitting method with economy based on the resilience-considered benefit–cost ratio.

多地震作用下桥梁改造方法的弹性考虑地震风险评估和缓解
摘要
为了根据经济性确定适当的桥梁结构改造方法,本工作提出了桥梁的年度预期弹性指数,以模拟给定时期内多次地震事件引起的考虑弹性的地震风险。除了直接成本,考虑到弹性的间接成本也包括在地震风险和收益成本比中,以确定适当的桥梁结构改造策略。在这项工作中,以台北的一座桥梁为例,应用所提出的量化方法来确定基于弹性考虑的效益成本比的经济改造方法。
