EN Soil-steel composite structures are usually designed with the use of analytical methods presented in such standards as SDM, CHBDC, or ASHTOO. Nevertheless, none of those standards introduces an analytical method for designing flexible foundations. Therefore, such foundations are usually designed with the use of time consuming and labor intensive full FEM analysis. In this paper the author makes an attempt at using classical foundations engineering solutions and models a corrugated steel plate foundation as an elastic beam on Winkler foundation. Moreover, he tries to find a method that takes into account layered configurations of geological substrates. Subsequently, the obtained values are compared against corresponding FEM analysis results. Likewise, the author evaluates the usefulness and accuracy of the presented computational approach.
