Centrifuge Modeling and Analysis of Concrete Gravity Dams

Journal of Structural Engineering, 1995
In gravity dams, crack growth is inhibited by gravitational effects; thus, correct model testing can only be accomplished in a centrifuge where the gravitational field is inversely proportional to the scale. Following an overview of centrifugal testing, this paper reports on the first centrifuge testing of concrete gravity dam models.

Fragility Analysis of Concrete Gravity Dams

Journal of Infrastructure Systems, 2001
Concrete gravity dams are an important part of the nation's infrastructure. Many dams have been in service for decades. During the service life of a dam, operating conditions and natural environmental factors may have led to some deterioration in its structural integrity, mechanical equipment, and foundation.

LEFM Applications to Concrete Gravity Dams

Journal of Engineering Mechanics, 1997
The evaluation of the safety factor of old dams under higher flood levels in the last few years has been investigated under the assumptions of fracture mechanics. The extensive need for research in this field was recognized by the U.S. Army Corps of Engineers that now requires a fracture mechanics investigation prior to the rehabilitation of cracked ...

Seismic stability of concrete gravity dams

Earthquake Engineering & Structural Dynamics, 1989
AbstractLinear finite element analyses are commonly used to simulate the behaviour of gravity dam—foundation systems. However, the foundation is generally unable to develop any significant tensile stresses. Therefore any tension occurring in the vicinity of the dam—foundation interface is largely fictitious.

Seismic behavior of concrete gravity dams

Advances in Computational Design, 2016
Dams 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 ...

Control of Cracking in Concrete Gravity Dams

Journal of the Power Division, 1959
Fundamental 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.

Stability Analysis of Concrete Gravity Dam

Applied Mechanics and Materials, 2012
The 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.

Earthquake Response of Concrete Gravity Dams

Journal of the Engineering Mechanics Division, 1970
The 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 ...
