| 摘 要： | 基于《公路工程抗震设计规范》(JT J 004-89)的弹性反应谱建立了地震弹塑性需求谱,并从解决桥梁结构的实际问题出发,根据桥梁结构的震害规律和特点,考虑桥梁结构的位移延性、耗能特性等方面因素,利用Push-over方法建立了桥梁结构的能力曲线,应用相应的地震需求谱具体分析了实际桥梁结构的破坏极限状态,为桥梁结构抗震性能评价的研究提供参考意见。

| Abstract: | In this paper,the seismic demand spectra are obtained based om Specifications for Earthquake Resistant Design for Highway Engineering(JTJ 004-89).The Push-over analysis method is employed to study capacity cover and earthquake performance of practical bridge structures according to earthquake damage characteristics of bridge structures.It is straightforward to assess seismic vulnerability of real bridge structure by employing seismic demand.This study will provide referrence for earthquake-resistant capacity decision in practical bridge structure. |
