地震工程学在桥梁抗震设计中的应用研究

Application of earthquake engineering to seismic design of bridges

在我国目前的桥梁抗震设计和分析中,主要研究的是各种类型桥梁的地震反应分析方法、设计方法、抗震构造措施等,对地震工程学方面的理论研究甚少,从而导致地震学与结构抗震两者之间缺乏联系,脱离了地震谈抗震。近年来,随着基于性能的地震工程学和抗震设计理论的出现以及不断发展,地震学的重要性日益凸显,因此必须将地震学与结构抗震有机联系起来。

Focuses of seismic design and analysis of bridges are on seismic design methods and details and anti-seismic structure measures for all kinds of bridges but not earthquake engineering at present.It causes the lack of relation between seismic design of bridges and earthquake engineering.Seismology is becoming increasingly important with the development of performance-based earthquake engineering.So seismology must be linked with seismic design of bridges.
