摘要
基于ＡＰＩ推荐的简化疲劳分析设计方法，提出了一组平台疲劳寿命预测的简化模型，可以大大简化疲劳寿命预测的计算工作量，方便工程应用；同时给出一个计算实例，４桩腿小型导管架平台的疲劳寿命及其可靠度的评估，可供工程参考。
This paper presents a simplified model of fatigue life prediction for offshore structures,which is deve loped on the basis of fatigue strength check method proposed by API RP 2A.The fatigue analysis using this model take less calculation time in comparison with spectrum method or direct discrete wave method.Fatigue life and riliability of four pile jacket platform is estimated by means of the model as an example.
