Simplified Framework for Preliminary Estimates of Bridge Bearing Demands and Fatigue Loading

While bridge bearings are ubiquitous, there is minimal information available on their performance lifespan bringing uncertainty to bridge rating and maintenance. The assessment of the life expectancy of bridge bearings requires proper estimation of the bearing demands under working conditions. These demands can vary significantly depending on the loading type (e.g., temperature, traffic, or seismic events), bridge configuration (e.g., geometry …
