✦ Synopsis

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 varying parameters such as ratios of dimensions and Poisson's ratio. Rigid foundations on the surface and with embedment are considered for all translational and rotational motions. In a practical analysis of soil-structure interaction this dynamic model of the foundation is coupled directly to that of the structure, whereby a standard dynamics program is used.

The vibrations and damping characteristics of an annular plate with constrained layer damping (CLD) treatment subject to a traveling spring-mass-damper (SMD) are investigated. The equations of the CLD-treated plate are first derived from the energy principle. These equations are simplified via the D
