摘要
《公路桥梁抗震设计细则》(JTG/TB02-01-2008)的颁布实施引起国内外学者的广泛兴趣与关注。在该规范(JTG/TB02-01-2008)和欧洲规范8(Eurocode8)_桥梁抗震设计中,对抗震设防目标、抗震设防分类、反应谱和地震作用进行比较和研究。研究表明,两者在抗震设防目标、抗震设防分类和反应谱方面具有相似性;在地震力折减方面有很大不同;最后指出采用不同地震力折减方式存在的不足,指出需要进一步研究的问题。
The promulgation and implementation of the Guidelines for Seismic Design of Highway Bridges（JTG/TB02-01-2008）have attracted interests and attentions of many researchers at home and abroad.The provisions about seismic fortification aims,seismic design categories,response spectrum and earthquake action are compared and analyzed between Guideline（JTG/TB01-02-2008） and Eurocode 8.The results indicate that it the aspects of seismic fortification aims,seismic design categories and response spectrum are similar,but the strength reduction factors are very different.At the end,the existing problems in strength reduction factors are pointed out,and the trends of future studies are discussed.
