Spring-dashpot-mass models for foundation vibrations
1998-12-4 The foundation on deformable soil, which, in general, radiates energy, can be represented in structural dynamics as a simple spring-dashpot-mass model with frequency-independent coefficients. For the two limiting cases of a site, the homogeneous half-space and the homogeneous layer fixed at its base, the coefficients are specified in tables for

2019-11-6 (spring rate, damping) can be highly indeterminate. In many cases, the calculations are complex and many assumptions are made. Energy dissipation does occur in soil; however, the rate of damping and the natural frequency are a function of the magnitude of the vibration input and foundation geometry.
