Dynamic response of low truss bridges subject to lateral loads

摘要

This paper presents 3D finite element model construction, modal analysis and lateral dynamic response of the low truss bridge instead of vehicle-bridge interaction model. We change general vehicle-bridge interaction model into low truss bridge model applied on lateral dynamic loads from running vehicles. Specifically, the determination of two different transverse dynamic loadings on the railways is included from wheel-rail creepages and uneven rail profiles respectively.
