【摘要】：为了促进桥梁结构全寿命抗震设计研究在中国的发展,详细论述并总结了基于全寿命周期的桥梁结构抗震性能评价与设计方法在国内外的研究进展,同时建立了其研究体系的基本框架。首先介绍了钢筋混凝土桥梁结构在其全寿命周期内遭受以氯离子腐蚀作用为主的环境作用分析模型的研究成果,在此基础上着重介绍了以桥梁结构地震易损性分析方法为代表的抗震性能评价方法与地震损失成本评估方法的研究进展,最后论述了基于全寿命成本分析的桥梁结构抗震优化设计方法研究现状。研究结果表明:基于全寿命周期的抗震性能评价和设计方法能够合理地解决传统抗震设计方法中未考虑结构抗震性能退化的问题,对于桥梁抗震工程领域的发展具有重要意义。
[Abstract]:In order to promote the development of the research on the whole life seismic design of bridge structure in China, the research progress of seismic performance evaluation and design method of bridge structure based on the whole life cycle is discussed and summarized in detail. At the same time, the basic framework of its research system is established. Firstly, the paper introduces the research results of the environmental action analysis model of reinforced concrete bridge structure subjected to chloride ion corrosion during its whole life cycle. On this basis, the research progress of seismic performance evaluation method and seismic loss cost assessment method, which is represented by seismic vulnerability analysis method of bridge structure, is introduced emphatically. Finally, the research status of seismic optimization design method of bridge structure based on life cost analysis is discussed. The results show that the seismic performance evaluation and design method based on the whole life cycle can reasonably solve the problem of structural seismic performance degradation which is not considered in the traditional seismic design method. It is of great significance for the development of the seismic engineering field of bridges.
