| Abstract: |
Eurocode fatigue load models for bridges have been developed using traffic information gathered from Western and Central European roads. This study was carried out to determine how fatigue loads from Finnish traffic typography compare to the fatigue load models defined in Eurocode. A comparison was made between Eurocode Fatigue Load Model 3 (FLM3) and damage determined from recorded Finnish traffic data. Computer software was developed for the analysis that utilizes the recorded traffic data to determine fatigue damage for selected representative structural details. The results indicate that generally FLM3 provides overly conservative results with the studied bridges, but can also theoretically underestimate fatigue loads when using Finnish traffic typography. |
