This study is the second phase of the cooperative research project concerning interaction effects in the seismic response of arch dams. It is a continuation of the work reported previously on the dynamic behavior of Xiang Hong Dian Dam. The experimental and analytical procedures employed in this study were the same as those used on the first dam; the essential difference between the two studies is that Quan Shui Dam is a thin-shell doubly curved arch, whereas the first test structure is a single curvature gravity arch. Thus, the interaction effects due to both reservoir and foundation are significantly different in the two cases as are the basic vibratory properties. The basic conclusions that were drawn previously about the mathematical modeling of the interacting system still seem to be valid; the volume of rock and of the reservoir that should be modeled seems to be similar for both types of structures. However, the analytical correlation obtained in the study of Quan Shui Dam is significantly less satisfactory than was found in the first study. Further study will be needed to determine the reason for the lower quality correlation obtained in the investigation of Quan Shui Dam.
