目前桥梁工程抗震的研究问题是当今热点问题,现就在分析桥梁结构地震破坏的主要形式基础上,阐述了桥梁抗震设计原则,最后对于桥梁抗震设计方法进行分析,重点探讨了桥梁抗震概念设计、桥梁延性抗震设计、地震响应分析及设计方法的改变以及多阶段设计方法等内容。 At present, the research on seismic response of bridge engineering is a hot issue nowadays. Based on the analysis of the main forms of earthquake damage to the bridge structure, the seismic design principles of the bridge are expounded. Finally, the seismic design method of the bridge is analyzed. Bridge ductile seismic design, seismic response analysis and design method changes and multi-stage design methods and so on.
