 Given that the scope of the results and recommendations is limited to the samples considered for the analyses, it is expected that the results will have a more comprehensive application than those considered in the present analyses. The results of the Karun 3 double curvature arch dam are as follows:

-For further non-dimensionalizing the displacement changes of the dam crest, based on the height of the water behind the dam, we targeted the maximum displacement of the dam crest, which is 97.98 mm.

In the Northridge and Kobe near-field earthquake, stress and damage are concentrated on the dam body, near the foundation and dam boundary due to the high dynamic pressure in the fluid and dam body, and in the Bam near-field and Chi-Chi, Manjil and Hector far-field earthquakes, Maximum stress concentration has shifted to the dam bottom.
