WebThe present paper contains a critical study of a number of foundation models as well as a further development of some of the ideas involved. Among others it is shown that the Pasternak foundation is a mechanical model for the so-called “generalized” foundation. WebTimoshenko beam on Pasternak foundation model is simplified into the equivalent SDOF system by using exact mode shapes. The generalized displacement is calculated by solving the uncoupled modal equation via Runge-Kutta algorithm. Finally, time-history responses are obtained by sum of contribution of each mode.
