| Abstract: |
The accumulated fatigue damage (for typical material dependent SN-curves) of simulated traffic was firstly compared to the characteristic static load model LM1 and secondly to accumulated fatigue damage caused by design fatigue load models. The study was conducted to two span bridges having variable span lengths and transversal stiffness characteristics. The study gives guidance to national authorities to pinpoint the most vulnerable bridge types in the bridge stock and the bridges sensitivity to frequent heavy special transportations. In addition, important information about the behaviour and functionality of Eurocode’s fatigue design approach is gained. |
