| Abstract: | On the basis of the hypothesis that a structural fatigue life accord with the two parameters Weibull distribution the ralationship between the risk of structural failure expressed as the structural detail fatigue rating and the service life are determined.To cite as an example,the calculating curve of the failure risk verus the service life is obtained. |
