A new effective procedure is proposed for evaluating the earthquake response of concrete arch dams including dam-reservoir-foundation interaction effects. The method is developed by integration of the most recent techniques designed to save computational time in different parts of the dynamic analysis of the complete dam-reservoir-foundation system. These are employment of the modified-efficient fluid hyper-element for modeling of the far-field of the reservoir, efficient evaluation of coupled mode-shapes of the system, and other alternatives for the main core of the procedure. Also, Morrow Point dam is analyzed and execution time saving in different parts of this analysis are provided and discussed.
