摘要
对平台用钢的焊接疲劳性能进行了研究 ,采用威布尔分布对试验数据进行了分析。给出各种可靠度下的R—S—N曲线估算式 ,并与对数正态分布处理的结果进行了比较 ,对海上石油钻井平台的安全性评估具有一定的意义。
The experimental investigation of fatigue behviour of welded joints in offshore structure are described. Life estimate formulas for R—S—N curve are derived based on the Weibull distribution, and the results are compared with the result based on logarithmic mormal distribution. It is possible to predict thd safty and reliability of offshore structure.
