| Abstract: | A study on soil-structure interaction problems using infinite elements is presented. To discretize the far field of the unbounded soil media, axisymmetric dynamic infinite elements which are capable of propagating multiwaves are developed. An efficient numerical integration scheme for constructing the element characteristic matrices of the infinite elements is devised based on Gauss-Laguerre quadrature. The efficiency of the infinite elements is demonstrated by calculating the impedances of the rigid circular footings, which are placed on an elastic half space and on layered half spaces. |
