This paper uses theoretical simulations to analyse the effect of a five-axle articulated truck on the dynamic response of a short-span bridge. Three-dimensional finite element bridge and truck models are developed with NASTRAN software. The bridge model is a 20 m long single span structure discretised into isotropic plate elements. The truck model is composed of bar, mass, damping, friction, spring and rigid elements. The road profile is generated stochastically from power spectral density functions. Then, the dynamic interaction problem between bridge, truck and road profile is solved using a Lagrange multiplier technique. Dynamic amplification factors are obtained for a combination of static weights, speed, road roughness and damping and compared to the Eurocode recommendation.||Type of material:||Conference Publication||Publisher:||Bridge Research Group UCD||Start page:||3||End page:||11||Keywords:||Five-axle trucks; Critical load; Short span bridges; Dynamic interaction; Impact factors||Other versions:||http://www.cerai.net/page/15/past-conferences/||Language:||en||Status of Item:||Peer reviewed||Is part of:||Proceedings of the First Symposium on Bridge Engineering Research Activity in Ireland||Conference Details:||The First Symposium on Bridge Engineering Research Activity in Ireland, Dublin, Ireland, 30 August 2002|
