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.
