STUDY OF DYNAMIC INFINITE ELEMENT USED FOR SOIL STRUCTURE INTERACTION

Starting from two-dimensional (2D) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. Two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. By coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for simulation of wave propagation in an unbounded foundation due to external forces.
