| Abstract: | Based on the function of failure rate h(n), this paper discusses the unreasonableness of presuming that fatigue life is subjected to normal distribution and formulates the equations for computing the fatigue reliability of steel bridge components on the presumption of fatigue life being subjected to Weibull distribution. |
