Abstract
A computer aided method of analysis has been presented for continuous, curved slab type bridge decks by incorporating method of finite difference in conjunction with the method of consistent deformation. Using a Levy-type series formulation, equilibrium difference equations are written only along the central radial line of the simply supported deck, by removing the discrete, redundant pier supports. Using the method of consistent deformation, the pier support reactions are determined and hence the entire support structure is solved. The computational procedure based on this one-directional finite difference method is repetitive and obviates the need of a large number of nodal equilibrium equations spread throughout the plate.
