Vibrations of Viscoelastic Halfspace
Апстракт
Numerical model of the soil is an essential part of the dynamic soil – structure interaction analysis. The soil model should take into account various phenomena that may occur due to dynamic loading, first of all radiation damping. In this paper, the damping phenomena is investigated by comparing the results of two different modeling approaches: analytical and discrete. Analytical model, developed by author, is obtained by using Integral transform method, based on Lame's differential equations solution. Discrete model is based on the finite element method and commercial software package Abaqus. Soil is considered an elastic, homogeneous and isotropic halfspace. Vertical vibrations due to dynamic force are considered. The results, presented for 3 characteristic frequencies, are in good agreement.
