In order to evaluate earthquake response of structures affected by shallow soft soil deposits, centrifuge tests were performed. The test specimen was composed of a single-degree-of-freedom structure model, a shallow foundation and sub-soil deposits in a centrifuge container. The structure response directly measured from the test showed that a large rocking rotation occurred due to the soil-foundation interaction. Thus, the acceleration of the structure was significantly smaller than the fixed base structure response.
