大跨径连续刚构桥抗震分析及抗震性能评价

Seismic Analysis and Seismic Performance Evaluation for Large-span Continuous Rigid Frame Bridges

以高速公路上的1座连续刚构桥(90 m+2×160 m+90 m)为例,参考新实施的《公路桥梁抗震设计细则》和国外相关规范,对大跨径连续刚构桥梁抗震分析和抗震性能评价的整个过程进行论述,为类似桥梁的抗震设计提供参考。

With one continuous rigid frame bridge （90m ＋ 2 × 160m ＋ 90m） on expressway for example and by reference of newly implemented ＂Detailed Rules for Aseismic Design of Highway Bridges＂ and the relevant foreign codes, this paper expatiates the whole process of the aseismic analysis and aseismic performance evaluation for large-span continuous rigid frame bridges to provide a reference for aseismic design of similar bridges.
