摘要
针对我国现行《水运工程抗震设计规范》的设计理念和方法的不足,对高桩码头的4种典型失效破坏模式进行总结,重点对比国内外有关码头结构抗震设计规范设防目标、概念设计、弹塑性分析方法的具体要求。工程案例计算结果表明,FEMA-440推荐的系数调整法的结果,与地震反应谱法和替代结构法的结果基本一致。
In view of the shortcomings of the design concept and approach of Chinese current Code for Seismic Design of Water Transport Engineering ,we summarize four typical failure modes of pile-supported wharf,and focus on comparing the specific requirements of the seismic design criteria,conceptual design,elastoplastic analysis method in the international and Chinese current codes about seismic design of wharf structure.The calculation results of example show that the results of the coefficient modification method recommended by FEMA-440 are basically consistent with the modal spectral method and substitute structure method.
