摘　　要：本文以某海外工程强震区的高桩结构为例,基于PIANC和ASCE/COPRI 61-14、POLB等现行国际抗震设计规范,总结了在实际Pushover抗震分析过程中如何应用国际规范确定动力放大系数、容许应变限值、材料期望性能、塑性铰长度等关键参数和如何考虑P-delta效应、地震荷载组合、地震质量等相关规定,可为类似项目的设计提供参考。Based on piled structure adopted in an overseas project located in strongly seismic zone,the current international norms of seismic design such as PIANC,ASCE/COPRI 61-14 and POLB are followed to summarize the experience in the application of international codes to determine the key parameters such as dynamic amplification coefficient,allowable strain limit,material expected performance,plastic hinge length,and to consider P-delta effect,seismic load combination,seismic mass in the process of actual Pushover seismic analysis,which can provide a reference for the design of similar projects.
