An iterative method to evaluate the impedance matrix of finite-size foundation
Abstract
A new approach used in the finite element method to calculate the impedance matrix of rock (or soil) foundation, is presented. First, an iterative technique is developed to solve the complex-valued equations of motion for the foundation subjected to a harmonic surface force. The proposed technique can be used to calculate the complex-valued displacement response of the foundation in an adjacent area near a certain exciting frequency. Second, …
