| 摘 要： | 在美国高桩码头抗震设计规范的基础上,从设计流程、设计地震动和性能目标、材料特性、结构分析模型、抗震分析方法等方面,介绍了高桩码头基于位移的抗震设计方法,并对规范采用的方法及有关问题进行解释,通过一个工程案例说明高桩码头基于位移的抗震设计的实施过程。基于位移的抗震设计可以很好地实现多地震水平、多设防目标的抗震设计思想,是目前和未来高桩码头抗震设计发展的方向。

| Abstract: | An introduction to the displacement-based seismic design method of pile-supported wharf is presented,highlighting on the design ground motion,performance objectives,material properties,structural analysis model and seismic analysis methods,and some explanations for the methods are made.Based on the American codes,a case study is conducted to demonstrate the implementation of displacement-based seismic design strategy.It is apparent that displacement-based seismic design strategy fulfills the requirements of multi-seismic level and multi-performance objectives,and will be the trend of seismic design for pile-supported wharf. |
