Seismic Analysis of Concrete Arch Dam Considering Material Failure Criterion
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Since large dams collapse can lead to catastrophic consequences on human’s lives and properties, the reliable performance of such structures during a strong earthquake is extremely important. Therefore, applying reliable analysis methods for designing large dams and seismic evaluation of the existing dam is crucial.
