【摘要】 分别从抗震设计的基本思想、设计地震动参数、地震动反应分析方法、构造细节等方面对我国《铁路工程抗震设计规范》(GB50011—2006)与美国《AREMA》抗震篇进行较为详细的对比,并选取最具代表性的简支梁桥,分别按中美两国铁路抗震规范进行设计研究,得出两国规范的差别主要体现在地震力组合、抗震构造细节及桥梁基础的抗震设计上。更多还原

【Abstract】 The author makes a comparison between Chinese Code for Seismic Design of Railway Engineering(GB50011—2006) and American AREMA,respectively in view of some issues,such as the seismic design basic idea,design parameters of ground motion,seismic response analysis method,structural details and so on.Furthermore,taking the most representative simply-supported girder bridges as the examples,the author carries out the design research on these examples respectively according to Chinese and American railway seismic standards.The conclusion drawn from this comparative study is: seismic force combination and structural seismic details and bridge foundation seismic design method are the main differences between the seismic standards of the two countries.更多还原
