Abstract
Tables of impedance functions and effective input motions for rigid square foundations embedded in a uniform elastic half-space are presented. The tables include numerical results obtained by a hybrid approach for embedment to half-width ratios ranging from 1/3 to 3/2 and by a boundary element method for surface foundations. Media characterized by Poisson's ratios of 1/4, 1/3 and 0.4 are considered. The impedance functions include vertical, torsional, horizontal, rocking, and coupling terms. Effective foundation input motions for vertically incident P and SH waves and for horizontally incident SH waves are also listed.
