Title: Impedances of rigid cylindrical foundations embedded in transversely isotropic soils
Author: Barros, PLA
Abstract: A complete formulation and implementation for assessment of the response to dynamic loads of cylindrical rigid structures embedded in transversely isotropic elastic half-spaces is presented. The analysis is performed in the frequency domain and the steady-state structure response is obtained. The method is based on a non-singular version of the indirect boundary element method which uses influence functions, instead of Green's functions, as fundamental solutions. These influence functions are the response of an elastic half-space to distributed, internally applied loads. The proposed method imposes full bonding contact between the foundation and the surrounding soil. Numerical results for displacement (vertical and horizontal) and rotation (twisting and rocking) impedances, showing the influence of the soil anisotropy, are presented. Results for the soil-structure interface tractions and for the displacement field throughout the half-space are also shown. Copyright (c) 2006 John Wiley & Sons, Ltd.
