For existing bridges, traffic simulations based on measured traffic data, can provide a more accurate prediction of the characteristic load effect for assessment purposes. However, this procedure only provides the characteristic static loading or load effect. The total static-plus-dynamic load is often estimated based on conservative factors due to the high degree of uncertainty involved in the dynamic interaction between traffic, road profile and bridge. This paper aims to reduce this uncertainty by using simple dynamic models to obtain an understanding of the speeds and axle spacings that cause the highest dynamic amplifications.||Type of material:||Conference Publication||Publisher:||Thomas Telford||Copyright (published version):||2005 the Authors||Keywords:||Bridge dynamic amplification;Speed;WIM||DOI:||10.1680/bmf.33542||Language:||en||Status of Item:||Peer reviewed||Is part of:||Parke, G.A.R., Disney, P.
