The method is based on stationary half-space compliance functions which have been accurately synthesized for high frequencies. The transient response is obtained by the FFT algorithm. The procedure is applied to investigate the effects of distinct viscoelastic soil models and parameters. The constant hysteretic, the Kelvin-Voigt and a ramp-like damping models are investigated. The effects of the viscoelastic models on the causality of the transient response is also reported. The transient response of 3D foundations possessing inertia properties is also addressed.
