The subject of this reaserch was creation of detailed vehicle-bridge interaction model, taking into account all degrees of freedom of the vehicle and shape of the structure crosssection. A parametric analysis is made in order to investigate which of the vehicle and structure parameters affect their behaviour and to what extent. The aim was to examine whether modelling of the bridge structure as a plate is adequate for obtaining accurate results, and which of the moving loading models gives results approximate to the ones obtained from experimental testing. Two types of structure were analysed: simply supported plate and simply supported stiffened plate. Five types of moving loading were observed: moving force, moving mass, sprung mass model (with 2 degrees of freedom), two-dimensional vehicle model (with 5 degrees of freedom) and three-dimensional vehicle model (with 9 degrees of freedom). Structure is discretised with use of the flat shell strip elements. In order to discretise and couple vehicle model with the structure, vehicle strip element is introduced. Different iterative procedure is proposed for the vehicle-structure interaction analysis with the application of finite strip method. An influence analysis is made for moving loading velocity, vehicle and structure mass ratio, structure cross-section shape and stiffness and geometric properties of the structure surface, concerning dynamic displacement of the structure. Finite strip plate model for a moving force and a moving mass loading is tested by comparison of numerical results with the closed-form solution. Interaction model for the complex spatial structure (stiffened plate) and a full vehicle model is verified in the way that interaction analysis results are compared with the ones obtained during experimental dynamic testing of the road bridge. Dynamic amplification factors are calculated from numerically obtained static and dynamic bridge displacements and they are compared with values from the literature.
