VD Vlachovice - concrete gravity dam
, 2022 As a part of this bachelor thesis an alternative design of the concrete gravity dam VD Vlachovice was made, to the already design of the earth-fill dam. The design of the outlet works, intake and spillway were also carried out as a part of the study. The

Fracture analysis of concrete gravity dam under earthquake induced loads [PDF]
, 2013 In this paper, seismic fracture behavior of the concrete gravity dam using finite element (2D) theory has been studied. Bazant model which is non-linear fracture mechanics criteria as a measure of growth and smeared crack was chosen to develop profiles ...

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 ...

Thermal-stress behaviour of RCC gravity dams [PDF]
FME Transactions, 2015 Roller Compacted Concrete (RCC) is a special concrete mixture with low cement content, frequently used for concrete gravity dams. This paper deals with the 3D finite element model for unsteady phased thermal-stress analysis of RCC dams. Model calibration

Seismic Performance Differences between Hardfill Dam and Gravity Dam [PDF]
长江科学院院报[Objective] To reveal the differences in seismic performance between hardfill dams and concrete gravity dams， this study investigates the nonlinear seismic response of the Oyuk dam （a typical hardfill dam） in Turkey and the non-overflow section of the ...

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 ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Despite the crucial need for fully quantitative risk assessment of large‐scale structures, their performance is typically assessed through deterministic or semi‐quantitative approaches. The main preventing factor is the computational burden of probabilistic seismic analyses.
