Dynamic stiffness of rectangular foundations
Abstract
The boundary element method is used to determine the dynamic stiffnesses of rectangular foundations resting upon or embedded within an elastic half-space. The effects of mesh size and relaxed versus nonrelaxed boundary conditions are investigated for square surface foundations. The static stiffnesses and the frequency dependent stiffness coefficients are then obtained as a function of the aspect ratio for rectangular foundations. Solutions for embedded foundations are obtained and results showing the effects of the embedment ratio are presented.
