An optimal aseismic design of massive structures requires detailed understanding of dynamic soil-structure interaction effects. The dynamic soil-structure interaction effects may be characterized by impedance functions that represent the force displacement relationship between the foundation and the surrounding soil. In this paper, the author has made a comparative study on dynamic impedance functions for surface foundations on an elastic half space by using various methods. One of the methods is a procedure newly proposed by the author, that is based on the direct numerical integration of Green's functions over the foundation when calculating impedance functions estimated by the displacement at the center point or the average displacement over the foundation. It should be noted that the proposed method is efficient for those cases and that the boundary element method is recommended when calculating impedance functions for rigid foundations.
