Abstract
Vertical vibration tests on surface and embedded footings of different dimensions were performed by Fry (1963) and Beredugo (1971). Analytical predictions were reported by Manyando (1991) based on nonlinear, frequency independent stiffness and damping coefficients for surface foundations. The authors present, in this paper, a mathematical model for predicting the response, in terms of amplitude versus frequency, for surface or embedded, irregular shaped foundations system under vertical vibration considering soil non-linearity and frequency dependent stiffness and geometrical damping parameters. The frequency dependent stiffness and geometrical damping parameters are based on Gazetas's work (1991). The predicted and measured natural frequency and resonant amplitude were in close agreement. The analysis provides strong support for the importance of using non-linear frequency dependent parameters analysis in evaluating the response of foundation systems subjected to vertical vibration.
