چکیده مقاله:

Evaluating response of earth dams to earthquake is an important issue in dynamic stability analysis of these structures. The calculation time and accuracy of seismic analysis of earth dams have always been one of the particular concerns of engineers. Wavelet-based decomposition of earthquake records, so that the frequency content does not change significantly, is one of the strategies that considered in the previous studies. In this method, in which the downsampling process is utilized, earthquake record points are halved. In the current research, seismic response of earth dam under main and decomposed earthquake records were evaluated using finite element modeling. Earthquake records were decomposed using wavelet downsampling method. The results showed an acceptable agreement between the earth dam response under decomposed and main earthquake records. Therefore, the decomposed earthquake records can be used in dynamic analysis.
