This study is the first phase of a cooperative research project on the interaction effects in the seismic response of arch dams, being carried out under the U.S.-China Protocol for Scientific and Technical Cooperation in Earthquake Studies. The dam is a single curvature arch located in Anhui Province, China. Measurements were made of the vibration behavior; the vibrations were excited both by rotating mass shakers and also by ambient vibration effects in the environment. The measured vibration mode shapes and frequencies were then compared with results obtained analytically using a finite element model of the dam, the reservoir, and the foundation rock. The purpose of the study was to evaluate and improve the mathematical models used to represent the foundation rock and the reservoir.
