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 bridge’s 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, is used to test the applicability of the conclusions obtained from the simple models to a realistic bridge/vehicle system.||Funding Details:||Not applicable||Type of material:||Journal Article||Publisher:||American Society of Civil Engineering (ASCE)||Copyright (published version):||2006 ASCE||Keywords:||Dynamic analysis;Velocity;Trucks;Amplification||Subject LCSH:||Bridges--Live loads
