Abstract
In this study, a dynamic analysis of machine foundations under vertical excitations is carried out. The effect of embedment and foundation geometry has been taken into account. The stiffness and damping of soil are considered as frequency dependents. A computer program (CPESP) in FORTRAN POWER STATION has been coded to evaluate the stiffness and damping coefficients depending on excitation frequency and embedment depth. Results have shown that increasing the embedment depth leads to increasing the resonant frequency and decreasing the amplitude of vibration.
