A modal approach is proposed for dynamic analysis of general concrete gravity dam-reservoir systems in frequency domain. The technique relies on mode shapes extracted by considering the symmetric parts of total mass and stiffness matrices. Based on this method, responses of an idealised triangular dam are evaluated and the convergences are studied under different conditions. The method is proved to be very effective and it is an extremely convenient modal technique for dynamic analysis of concrete gravity dams.
