Abstract: This report describes the Shear Ring Method and the computer program RingWall. The Shear Ring Method was developed based on observations that the conventional soil-structure interaction analysis (beam on elastic foundation) did not accurately duplicate the results of full-scale test results or plane strain finite element results on floodwalls. From tests and analyses, the principal mode of motion was found to be horizontal with a rotational component and the soil, as opposed to the pile, was the major component of the system that determines the overall deformations. The Shear Ring Method models the two-dimensional geometry of the pile-soil system using plane strain finite elements, but the analysis is reduced to a one-dimensional model as in the conventional SSI. The reduction is obtained by assuming that the soil deformation due to an unbalanced geometry or loading will result essentially in a rotational failure. This method was found to produce reasonably accurate results compared with those of nonlinear, plane strain finite element analyses of typical floodwall sections and is considerably easier to perform. The method was subsequently extended to single-anchored sheet-pile walls.
