Abstract

For several years the Equivalent Linear Method was the most used method to solve dynamic problems of stratified soil deposits. This is valid for soils showing small or medium nonlinearities. It is an iterative procedure without a mathematical approach associated to it. The proposed mathematical method is based on the use of the First and Higher Order Frequency Response functions as required by the Volterra series. This method is based in the determination of the functions that relates the input motion to the response. In this study, up to the third order frequency response functions (kernel) are developed. The use of these expressions in some numerical examples and a comparison with the Equivalent Linear Method will be presented. Also, a sensitivity ana
