Simplified calculations involving the maximum load on bridge fatigue details under inspection. Part II: Fatigue
AbstractFatigue crack growth implies that the maximum load that may be sustained by a bridge detail becomes a function of time. Two examples are studied here which demonstrate that, under a set of specified assumptions, the fatigue life under variable amplitude loading is approximately lognormal. Following this treatment, simplified calculations are presented which allow maximum load specification in terms of the failure probability and probability of time exceedence. The former is a function of the material parameters and the inspection method’s capability of detecting the fatigue crack, while the latter depends on the crack growth characteristics and time.
