Uncertainty analysis and risk identification of the gravity dam stability using fuzzy set theory [PDF]
Journal of Hydraulic Structures, 2022 This paper introduces a methodology in which the fuzzy theory has been used along with numerical modeling of a gravity dam. For this purpose, using the fuzzy set theory method, the Folsom gravity dam in the USA, which is modeled in ANSYS and CADAM ...

The damage to model concrete gravity dams subjected to water explosions
Defence Technology, 2023 Over the past century, the safety of dams has gradually attracted attention from all parties. Research on the dynamic response and damage evolution of dams under extreme loads is the basis of dam safety issues.

International Journal of Concrete Structures and Materials, 2020 This paper proposes an approach to assess and predict the seismic risk of existing concrete gravity dams (CGDs) considering the ageing effect. The combination of fragility function and cumulative absolute velocity (CAV) depending on two failure states ...

Near fault and far fault seismic analysis of concrete gravity dam [PDF]
Journal of Hydraulic Structures, 2020 Ground motions records of the past higher magnitude (Mw>5) earthquakes have indicated that ground motions recorded at the closest distance of the near-fault are very different from those recorded from a higher distance from the site of the far-fault ...

Fully Covariant Van Dam-Veltman-Zakharov Discontinuity, and Absence Thereof [PDF]
, 2002 In both old and recent literature, it has been argued that the celebrated van Dam-Veltman-Zakharov (vDVZ) discontinuity of massive gravity is an artifact due to linearization of the true equations of motion.

Factors influencing hysteresis characteristics of concrete dam deformation
Water Science and Engineering, 2017 Thermal deformation of a concrete dam changes periodically, and its variation lags behind the air temperature variation. The lag, known as the hysteresis time, is generally attributed to the low velocity of heat conduction in concrete, but this ...
