| 摘 要： | 提出了一种评估结构疲劳可靠性的方法－风险预测方法。该方法利用结构在服股过役过程中的信息,在考虑了工程结构承采载荷的各态历经性的基础上,结合了结构元件寿命机分布形式和Ｍｉｎｅｒ线性累积损伤理论,以风险值来评价并监控结构元件在不同时间失效的危险性,并用算例和试验结果进行对比分析。

| Abstract: | A method of
fatigue reliability evaluation of structures, the Risk Forecast Method, is advanced in
this paper. This method uses the service information of the engineering structure and
combines the types of the structural elements’ life distributions and the Miner Liner Accumulated Damage
Theory based on the consideration of the similarity of engineering structural load series.
Risk value is used to estimate and monitor the danger while the structural elements lose
their effectiveness in different time. An example is given to analyze in comparison with
the result of experiment. |
