Abstract
To effectively evaluate highway bridges, the load spectra experienced must be determined. A fatigue live load model has been developed for girder bridges which reflects site specific conditions. Five bridges were tested to determine site-specific truck parameters and component-specific stress spectra. The data base includes gross vehicle weight (GVW), axle weights and axle spacing as well as stress cycles in the bridge girders. The weigh-in-motion measurements confirm that truck loads are strongly site-specific. A dual fatigue truck model is proposed. The developed model is verified using fatigue damage analysis to compare the model to measured results and existing models.
