摘要：In this work the behavior of Structures is analyzed considering the Interaction Soil - Stroctures. For this is studied the behavior of a rigid circular foundation supported in the surface of an elastic semi-space, isotropic and homogeneous, submitted to the action of a vertical harmonic load, which acts in the axis of symmetry of the foundation. It is obtained the vertical displacement from the base in the interface soilfoundation, whit the two criteria adoption for the condition from radiation energy: the removed contours and the transmitting contours.
