Summary

In many of the so called developed countries much infrastructure has been established, which has been designed as safe life, if a finite life has been considered. Strictly following a safe life approach requires such an infrastructure to be taken out of service once this finite life has been achieved. This is however economically often not possible since most of the infrastructure has become an asset of indispensable use. Taking advantage of a material's scatter in fatigue life however requires a more profound assessment of a structure in terms of the loads applied and the resulting degree of damage it can tolerate, how its current damage condition can be assessed and how its residual life can be estimated. This paper provides the concept for application for steel structures taking a steel railway bridge as an example. The idea in this case is based on the use of measuring the electromagnetic properties at different locations of a structure and correlating those to stress, strain and damage distributions on the one side and performing residual fatigue life evaluations on the other allowing an interesting life cycle management process to be initiated.
