Dynamic interaction between a building-foundation system and the supporting soil can significantly alter the earthquake response of the building depending on the characteristics of the system and the ground motion. The California Strong Motion Instrumentation Program obtained a large number of building response records from the 1 October 1987 Whittier Narrows earthquake. The instrumentation of a 14-story warehouse building included the nearby ground motion. Using this data, this study demonstrates that soil-structure interaction reduces the maximum base shear force in the building.
