- 摘要： It is necessary to thoroughly investigate the ultimate seismic capacity
of dam under rare strong earthquake. The seismic responses of arch dam
with transverse joints, under increasing levels of earthquakes, are
studied using FEM model. Based on this analysis, 3 stages division in
holistic seismic performance of arch dam is recommended. Considering the
uncertainty of peak ground acceleration, the probability of arch dam in
certain performance stage is calculated, and the result may be very
useful for the seismic evaluation of arch dam, comparing with the
approach of searching all the failure modes/paths. The prelimi? nary
study may give some hints in finding seismic performance evaluation
