Sažetak
— Stiffened plate analysis under the influence of standard european five-axle vehicle (semi- trailer) is presented. Flat shell strip is used for spatial discretization in order to reduce the number of unknowns and enable structure and vehicle models to be authentic as far as possible. Vehicle is introduced as 3D model with 12 degrees of freedom. Structure-vehicle interaction model presented here is described with the system of 13 differential equations which is solved using iterative procedure called impulse acceleration method. Results are compared with experimental data from literature. The results show that moving force and moving mass vehicle models are not appropriate for idealization of long heavy trailers. Since semi-trailers are standard in transportation classification it is important to know how they affect the bridge behavior. Dynamic influence is considerably reduced in relation to the plate bridge structure. While plate structure sustains 3D vehicle model only for small loading mass, it is not case with stiffened plate, so realistic results can be obtained.
