摘要: Abstract The nonlinear seismic fracture response of concrete gravity dams is conducted when the effect dam–reservoir interaction taken into account. included in time domain analysis using staggered solution method. Smeared crack model based on a mechanics propagation criterion used to study cracking and dam. Results are compared case was represented by added masses. It found that includes gives pattern close observed damage Sefid-rud dam during 1990 Manjil (Iran) earthquake. predicted different from approximated mass approach. concluded proper modelling important dams.
