For structures founded on soil deposits, the interaction between the soil and the structure caused by incident seismic waves modifies the foundation input motion and the dynamic characteristics of the soil-structure system. This paper reports that as a result, soil-structure interaction (SSI) plays a critical role in the design of nuclear plant structures. Recognizing that experimental validation and quantification is required, two scaled cylindrical reinforced-concrete containment models (1/4-scale and 1/12-scale of typical full-scale reactor containments) were constructed in Lotung, an active seismic region in Taiwan. Forced vibration tests (FBT) were also conducted to characterize the dynamic behavior of the soil-structure system. Based on these data, a series of round-robin blind prediction and post-test correlation analyses using various currently-available SSI methods were performed.
