| Abstract | In this study, a curved box-girder bridge which is simply sup ported along the two straight edges, free on the curved edges and subjected to a uniformly distributed load and vehicular wheel loads is analyzed as a segmental annular sandwich plate whose top and bottom facings are assumed to resist the bending and twisting moments while core medium is assumed to resist only the vertical shear. The problem is governed by three partial differential equations involving the plate deflection and two angles of rotation in the directions of polar coordinates employed in this study. The solutions are taken in such forms that the boundary conditions along the straight edges are satisfied. The resulting ordinary differential equations obtained upon the separation of the variables are in turn solved by the finite difference method. The numerical results agree very well with those obtained by the technique of curved strips. Since the convergence involved in obtaining results by the proposed technique is relatively fast, it is advantageous over other methods in reducing the computation time. The simplified solution based on neglecting the shear deformation associating with the bridge girders leads to a good prediction in deflection, very conservative girder moments and a very poor prediction of other stress resultants. |
