摘要：AbstractThis paper demonstrates how span lengths influence the result for assessment at the fatigue limit state when using a large amount of data from real trains. Nine fictitious bridge configurations are used with varying length and numbers of spans, thereby facilitating assessment of the impact of the different train configurations on the fatigue performance. Given a new traffic composition or the current traffic composition with a new allowed maximum speed for an arbitrary train route, the information from these calculations provides an improved basis for decisions concerning the need for bridge maintenance prioritization based upon susceptibility to fatigue damage.
