چکیده مقاله
Dam reservoir interaction affects modal characteristics of dam but its effect’s amount depends on amplitude of excitations and water level of reservoir In this paper, effect of dam reservoir interaction on modal characteristics of arch dams due to weak and strong ground motions investigated Finite element models of dam reservoir foundation and dam foundation systems excited due to weak and strong ground motions andmodal parameters of the system extracted by Frequency Domain Decomposition FDD and Continues Wavelet Transform CWT method based on dam responses to investigate the relation between amplitude of excitation and effect’s amount of dam reservoir interaction on natural frequencies of the system Effect of reservoir water level on natural frequencies of the system is also investigated
