中文摘要：
为了较准确获得海洋结构在设计环境荷载重现期下承受的风浪荷载,简述了Archimedean Copula函数的定义及特征,定义了样本的重现期安全域概念;对常用的几种重现期和基于Archimedean Copula函数C-测度的第二重现期进行了对比分析;首次将第二重现期应用于风浪联合分布的重现期分析中,经实际数据验证,第二重现期定义严格,计算结果更接近荷载效应实际重现期.
英文摘要：
To effectively obtain wind and wave loads for marine structural design in the return period of environ- mental loads, the concept and characteristics of the Archimedean Copula function are briefly described, and the se- curity domain of return periods of a sample is defined. Some common return periods and the secondary return period based on C-measure of the Archimedean Copula function are compared and analyzed. Secondary return period is firstly applied to the return period analysis of wind-wave joint probability distribution, and the data analysis shows that the definition of secondary return period is precise and the calculation results of secondary return period are closer to the return period of actual load effects.
