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 ...

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 ...

The collapse of the Sella Zerbino gravity dam
Engineering Geology, 2016 When a severe flood wave completely filled the Ortiglieto reservoir on August 13, 1935, the 14 m high "Sella Zerbino" secondary dam failed catastrophically causing > 100 casualties. Both of the dams, Sella Zerbino-Zerbino Saddle and Bric Zerbino-Zerbino Peak (Fig.

Progressive Failure Research on Foundation Surface of Concrete Gravity Dam
, 2010 Concrete dam safety is one of the hot issues in dam study with the increasing of dam’s scale and height. Sliding failure along foundation surface is a potential failure mode of concrete gravity dam, and this mode is relatively rare in practical ...

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 ...
