Bending Analysis of Stepped Rectangular Plates Resting on an Elastic Half-Space Foundation

In this paper, the bending behavior of rectangular plates with stepped thickness resting on an elastic half-space foundation is investigated through analytic method. Combined theory thin and moderately thick plate, plate divided into upper lower plates, Fourier series used to obtain analytical solution deflection interaction force between foundation. The influence modulus theory, dimension also discussed. results show that basically same as existing research results, it verified by analysis models established ABAQUS software. at center increases increase decrease side length while has little effect plate. This method not only overcomes some disadvantages numerical methods but eliminates assumptions Winkler model two-parameter model, thus obtaining a more reasonable accurate performance
