DYNAMIC INTERACTION BETWEEN THE VEHICLE AND SIMPLY SUPPORTED CURVED BRIDGE DECK

Vehicle-guideway interaction for a vehicle on simply-supported curved bridge decks is studied with the effects of Vehicle speed and guideway parameters taken into account. In the dynamic model, the vehicle is c onsidered to have four-degrees of freedom, with lumped masses, linear springs and dampers. Although the material and geometric linearities a re preserved in the formulation, the consideration of interaction betw een the vehicle and the bridge results in a nonlinear structural respo nse. The finite element method is used for solving the governing diffe rential equation of the vehicle-bridge system. In this paper, multi-pr edictor-corrector procedure in connection with the Newmark method, is employed for the solution of the resulting matrix ordinary differentia l equations. The deflection at the middle of the beam is determined fo r different vehicle speed end different radius of curvatures of the cu rved deck. (C) 1998 Elsevier Science S.A. All rights reserved.
