高架桥抗震设计一例

Brief Introduction of the Calculation of the Anti-Earthquake Bridge

结合西港高架桥 2 0m跨空心板抗震设计的工程实例 ,对桥梁抗震的计算方法 (静力法、反应谱理论、动态时程分析法 )进行分析和探讨 .力求在桥梁抗震设计中能够采用正确的计算方法 ,达到减少地震灾害的目的 .

Based on the example of the design of the 20m-hollow slab Xigang Anti-earthquake Elevated Bridge,calculation methods in bridge anti-earthquake(method of static, response spectrum theories,method of dynamic timing analysis)are analyzed and discussed. The right calculation method in bridge anti-earthquake design is adopted to decrease disastrous cost in earthquake.
