Abstract
ABSTRACT This paper presents an analytical solution to calculate the seismic earth pressure induced by Rayleigh wave in viscoelastic media using the three-dimensional wave propagation theory. Two soil-structure systems are considered: a substructure inserted into a homogeneous soil layer and a substructure surrounded by a multilayered soil profile. Closed-form solutions are proposed as functions of damping ratio, Poisson’s ratio, and the height of the substructure. Furthermore, two special cases were investigated to examine the influences of a loose and a stiff thin layer in the layered soil profiles. The results obtained for different scenarios were compared systematically in a comprehensive numerical example.
