Abstract

The study of framed structures on elastic foundations subjected to ground motion is considered using a model which combines conventional frame el- ements with elements obtained using the Winkler hypothesis. A series of different base excitations, including earthquake response spectra, are con- sidered. Results are compared with those obtained for similar structures not including the elastic foundations. 1 Introduction The formulation to be presented is based on the beam on a continuous elastic foundation which is a classical model of soil-structure interaction. The first detailed studies of the differential equation of the beam on a continuous spring considering the Winkler hypothesis of soil reaction pro- portional to deflection are due to Hetenyi [1]. The equation in its usual form for a beam
