This phenomenon, called as base-slab averaging effect or wave incoherence effect, can be explained that the spatial variations in the free-field motion are constrained by stiffness of the foundation within its footprint. Several approaches have been developed to consider the incoherence of ground motion as part of soil-structure interaction (SSI) analysis. However, most of them are based on the assumption of massless rigid foundation, or their applications are restricted to the simple surface structures. This paper presents parametric studies on the effect of foundation embedment in SSI analysis to incorporate spatial incoherence of seismic ground motion, and evaluates its feasibility on practical pressurized water reactor (PWR) structures. In addition, engineering application guidelines and further considerations including rocking and torsion are described.
