Seismic behavior of concrete gravity dams
Advances in Computational Design, 2016Dams play a vital role in the development and sustainment in a country. Failure of dams leads to the catastrophic event with sudden release of water and is of great concern. Hence earthquake-resistant design of dams is of prime importance. The present study involves static, modal and transient analyses of dam-reservoir-foundation system using finite ...

Stability Analysis of Concrete Gravity Dam
Applied Mechanics and Materials, 2012The safety is first-class important event of the dam. The crash for the gravity dam usually causes due to slid, the slippery stable is a key problem of big dam. This paper checks the stability of one dam by rigid body limit equilibrium method and finite element technique.

Control of Cracking in Concrete Gravity Dams
Journal of the Power Division, 1959Fundamental cause of temperature cracking in concrete gravity dams is restraint which accompanies temperature changes; evolution of crack control measures; role of cement factor, cement replacement material, concrete placing temperature, lift thickness, rate of placement, and insulation; current US Army Corps of Engineers practices and results.

Earthquake Response of Concrete Gravity Dams
Journal of the Engineering Mechanics Division, 1970The problem is simplified to a linear analysis of the two-dimensional vibration of coupled reservoir-dam systems, with the response of the dam being approximated by its deformations in the fundamental mode. Four cases are considered: dam alone (without reservoir); reservoir-dam system-interaction neglected; reservoir-dam system-interaction included ...

The earthquake experience at koyna dam and stresses in concrete gravity dams
Earthquake Engineering & Structural Dynamics, 1972AbstractA number of questions concerning the response of concrete gravity dams to earthquakes, motivated by the structural damage caused to Koyna Dam, which has an unconventional cross section, by the December 1967 Koyna earthquake, are considered in this work.

Seismic Cracking of Concrete Gravity Dams
Journal of the Structural Division, 1976A mathematical model describes properties of concrete under a two-dimensional state of stress. The effects of strain rate — the time rate of change of strain — on the mechanical properties are incorporated in the model. Appropriate assumptions are introduced in the model where experimental data were lacking; it was assumed, for example, that strain ...

Seismic behaviour of cracked concrete gravity dams
Earthquake Engineering & Structural Dynamics, 2005AbstractA finite element model of incremental displacement constraint equations (IDCE), based on an existing node‐to‐surface concept, is implemented to deal with dynamic contact surfaces in the seismic behaviour analysis of cracked concrete gravity dams.

Earthquake Analysis of Concrete Gravity Dam
2018For countries blessed with a number of rivers and lakes, where water management, flood control, and development of hydel power remains a major issue, concrete gravity dams often play a major role in achieving the same.

Pseudo Dynamic Test Results of a Concrete Gravity Dam
2014The 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.
