Abstract

Abstract

Bridge and vehicle were treated as two separate systems, vehicle was modelled as 2D nonlinear model, the effect of road surface roughness was considered, their dynamic equations were developed by virtual work theory and mode superposition theory, their uncoupled equations were solved separately by an iterative procedure while the geometrical compatibility condition and equilibrium condition of the interaction forces between bridge and vehicle were satisfied. The dynamic response of continuous girder bridge under moving vehicular loads was studied. The results show that the impact parameter when vehicle moving on side span is larger than the one when vehicle moving on middle span, the impact parameter is related to those factors, such as the dynamic properties and velocity of moving vehicle, the roughness of road profile and the dynamic properties of bridge, it is too simplified to take the impact parameter only as the function of the nature frequency of bridge.
