摘要
通过基于BS5400的桥梁焊接结构在给定失效概率下的疲劳寿命分析,对概率模型进行总结、分析、改进。在此基础上,探讨对桥梁结构关键构件的疲劳寿命做出任意概率可靠性的评估的方法。并对修正过的概率模型计算方法在实际应用中的可靠性进行了分析。
The primary assessment of fatigue life at given value of failure probability for bridge-deck section is made by using the detail classification on bridge components. In order to further modify the selected probability model based on BS5400, a modified probability model suitable for fatigue evaluation at any value of failure probability is obtained. Therefore it is verified that the modified mode is practicable for reliable evaluation of the service life in bridge-deck section.
