Spillway is composed of various structural elements such as piers, shafts, hoisting equipments, gates, and so forth. So, in order to evaluate seismic safety of spillway accurately, it is necessary to evaluate the mutual dynamic effects among these structural components of spillway. At the 1993 Kushiro-oki Earthquake (M7.8), earthquake damage occurred at the existing spillway. Taking the opportunity, the seismometers were installed at the dam and spillway after the 1993 Kushiro-oki Earthquake. Soon after that, the earthquake motions of maximum acceleration 709.52 gal at the top of concrete piers and 81.69 gal at the dam base were recorded during the 1994 Hokkaido-touhou-oki Earthquake (M8.2). Then, I made the 3-D dynamic analysis in regard to the actual earthquake behaviors of concrete piers of the spillway, and made clear the mechanism of earthquake damage of spillway.
