The development of state-of-the-art techniques for analyzing the effects of soil-structure interaction (SSI) on structures during earthquakes is outline. Emphasis is placed on methods to account for energy dissipation as a result of both wave propagation away from the structure's foundation and hysteretic soil response. Solution techniques are grouped into two major types: substructure methods, which break the problem into series of steps; and direct methods, which analyze the soil-structure model in one step. In addition to theoretical and historical development of SSI methodology, case studies are presented illustrating the application of these solution techniques. The case studies are designed to quantify the effects of parameters important to the response of nuclear power plant containment structures. Studies in the following areas are presented: 1) effects of foundation embedment; 2) composite modal damping; 3) effects of radiation damping; 4) fixed base assumption for foundation on rock; and 5) comparison of a substructure technique to a direct technique.
