摘要
API规范推荐的简化疲劳方法在渤海湾导管架平台使用中一直存在标定的问题。根据简化疲劳原理,利用渤海湾的环境数据,推导了渤海湾允许疲劳应力的表达式,在此基础上提出了计算设计疲劳年限的概念。既解决了标定的问题,又可以利用现有设计软件直接进行计算,具有很高的实用性。
The issue of calibration has always been there in the use of API-recommended simplified fatigue method for jacket platforms at Bohai Bay. So a closed-form expression of allowable fatigue stress for Bohai is derived from the simplified fatigue method on basis of environmental data of Bohai in this paper. Subsequently, a concept of calculation life for fatigue design is presented, which is very practicable in dealing with the issue of calibration for Bohai area and realization by generalized design software.
