Equation for the compliance of the ground, considered as an elastic half-space under a rectangular foundation slab, is developed for harmonic forces normal to the ground. Displacement of the center of the slab for several rectangular shapes is evaluated numerically and plotted as a function of the frequency. A closed-form solution for the limiting case of zero frequency is shown to agree exactly with the static problem of Love [7].
