Pseudo‐dynamic testing of a concrete gravity dam
Earthquake Engineering & Structural Dynamics, 2015 SummaryInspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo‐dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120‐m‐high monolith of the Melen Dam, one of the highest ...

Fracture analysis of concrete gravity dam under earthquake induced loads [PDF]
Journal of Applied Sciences and Environmental Management, 2011 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 ...

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 ...

Thermal analysis of concrete gravity dam
Tạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ, 2012 In practice of massive concrete constructions, cracks appear so popularly. Thermal behavior in concrete is the important cause of this problem.Based on this reason, the thermal analysis of concrete is very neccessary to find the reasonable solution to prevent cracking in design massive concrete constructions, especially hydroelectric power because of ...

Pseudo Dynamic Test Results of a Concrete Gravity Dam
, 2014 The energy and water demands have constantly been increasing all over the world due to rising population and due to advances in science. This fact obligates the usage of natural resources to supply more and more water and energy. Of course, the most important structures that can serve this purpose are dams.

STUDI KOMPARASI PEDOMAN DESAIN SEBAGAI REFERENSI INOVASI DAN DESAIN BENDUNGAN BETON GRAVITY
Jurnal Teknik Hidraulik, 2022 Concrete gravity dams continued to develop in Indonesia even though the population is still smaller than embankment dams. Until 2021 there consist of 16 concrete gravity dams or about 7% of all dams in Indonesia.

The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]
, 2010 The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...
