DYNAMIC ANALYSIS BRIDGE-VEHICLE SYSTEM FOR SUSTAINABLE DIMENSIONING ROAD DECK BRIDGE

The article presents a method to obtaining the dynamic response bridge-vehicle system in displacements, for sustainable dimensioning of the road decks bridge. The method used is the numerical finite strips method (FSM) associated with the Rayleigh-Ritz variation principle for determining vibration modes. The road deck bridge was considered to be made from reinforced concrete and is considered to be modelled by isotropic plate with varying boundary conditions. The vehicle is represented as a concentrated mobile force moving with speed V on the deck bridge. We will analyze the influence of slab thickness on the dynamic response of the system introduced.
