  • Effect of vehicle velocity on the dynamic amplification of a vehicle crossing a simply supported bridge
    Brady, Sean P. ; O'Brien, Eugene J., 1958- ; Žnidarič, Aleš
    Many writers, using both experimental tests and complex numerical models, haveexamined the effect of vehicle velocity on a highway bridgeʼs dynamic amplification. Although these tests and models give ... valuable quantitative information on dynamic amplification, they give little insight into how amplification is affected by individual vehicle/bridge parameters. This paper uses relatively simple numerical models to investigate the effect of vehicle velocity on a bridgeʼs dynamic amplification. A single vehicle crossing a simply supported bridge is modeled as a constant point force. A set of critical velocities are determined associated with peaks of dynamic amplification for all beams. The reasons for these large amplifications are discussed. A more complex finite element model, validated with field tests, isused to test the applicability of the conclusions obtained from the simple models to a realistic bridge/vehicle system.
