Abstract: This paper gives a finite prism superposition solution for a rectangular thick plate and thick plate with circular holes on elastic foundation. This method takes simply supported and sliding clamped structures as basic structures whose stiffness matrixes often have a very narrow bandwidth, thus significantly reducing the computational effort and storage requirements of three-dimensional analysis compared with three-dimensional finite element. In this method,a program has been developed. The prism element includes rectangular four-node-line prism and triangular three-node -line prism as well as eight-node-line isoparametric prism. The correctness of the method and program has been proved by many examples and tests.
