Calculation of Fatigue Crack Propagation Using Doproc Method

Abstract: Probabilistic calculation of steel structures and bridges using DOProC method, leads to the probabilities of three basic random events in dependence on years of bridge's operation and fatigue crack propagation. On the basis of that calculation for each individual year, determined by analysis of reliability function, the dependence of the failure probability on time of the bridge's operation is specified. When the limit reliability is known, it is possible to determine times of the structure's inspections using… Show more

A detailed description of theoretical background to the probabilistic calculation of propagation of a fatigue crack has been published in part, for instance, in [10,20,22,23,24].
