Original Abstract

The article presents the probabilistic analysis of the limit state function of the fatigue resistance of a steel bridge, which is numerically described as the total number of cycles to failure. An example of the evaluation of the histogram of the fatigue resistance of a steel member using the Latin Hypercube sampling method and linear fracture mechanics based on Paris-Erdogan’s law is presented. Probabilistic models of input variables for which the fatigue resistance has a typical log-normal probability density function are described. Differences between the stochastic analyses of one member with one edge crack and the entire steel bridge are discussed. Attention is paid in the limit state function to the effects of skewness and kurtosis of the fatigue resistance on the time-dependent failure probability.
