| Sumario: | The dynamic analysis of concrete arch dam by employing wavenumber approach has been investigating. In previous studies, the analysis was limited for concrete gravity dam. It is well-known that the difficult approach for solving this problem relies heavily on employing a three-dimensional semi-infinite fluid element. The hyper-element is formulated in frequency domain and its application in this field has led to many especial purpose programs which were demanding from programming point of view. In this paper, the method is initially described. Subsequently, the response of Morrow Point dam-reservoir system is obtained by wavenumber approach, and the results are compared against the exact response. Based on this investigation, it is concluded that this approach can be anticipated as a great substitute for the rigorous type of analysis. |
