This paper discusses the manner in which the stiffness of a slab-on-grade or building will alter the free-field vibrations at a building site. This phenomenon is dependent upon the rigidity of slab or foundation in the direction of wave propagation, and the relationship between wavelength and the dimension of the slab or foundation in the direction of wave propagation. Measurements from field studies are used as examples.
