Abstract
Several dams constructed along the San Andreas Fault were damaged by the fault displacement during the 1906 San Francisco Earthquake. And, the Shih-Kang Dam was destroyed by the fault displacement during the 1999 Taiwan Chi-chi Earthquake. In regard to the seismic safety evaluation against strong earthquake motions, the analysis methods have been practically developed, however the analysis method for evaluating the safety against fault displacement has not been established yet. In order to realize an evaluation method against fault displacement, I have devised the analysis method for discontinuous behaviors of concrete dams by applying 3-D dynamic analysis method for coupled dam-joint-foundation reservoir system. The applicability of the proposed method was examined by the analyses for concrete dam..
