Abstract:Current displacement based seismic design of gravity retaining walls utilizes a sliding block idealization, and considers only a translation mode of deformation. Authors update and extend the coupled equations of motion that appear in the literature. A newly developed fundamental theory on seismic bearing capacity of soils is used to compute the seismic resistance of bridge abutments and the resisting moment offered by the foundation soil.
