This paper presents dynamic infinite elements for soil-structure interaction analysis. In order to discretize the far field of the unbounded soil media, axisymmetric infinite elements which are capable of propagating multi-waves are proposed. An efficient numerical integration scheme for constructing the element characteristic matrices of the infinite elements in developed based on Gauss-Laguerre quadrature. The efficiency of the infinite elements is demonstrated by comparing the computed impedances of rigid circular footings on an elastic half space and on a layered half spaces with those obtained analytically.
