Pseudo dynamic test results of a concrete gravity dam

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. However, the behaviour of dams, especially under the effect of seismic actions, is one of the most complicated problems in earthquake engineering. This is because; dams usually rest on flexible foundations and interact with the water, which necessitates taking the dam-foundation-reservoir interaction into account. Also, complex geometry of the valley and the dam necessitate considering higher mode effects. A number of different linear elastic boundary element and finite element procedures were proposed in the literature to analyze the three dimensional dam-foundation-reservoir interaction problem rigorously. On the other hand, the seismic behaviour of concrete gravity dams has not been investigated experimentally in detail other than a few shaking table test programs because of the difficulties encountered during experimental simulations like hydrodynamic effects, huge sizes, etc. Consequently, the aim of this study is to carry out a pseudo dynamic test on a scaled concrete gravity dam. The base cracking, sliding, base shear capacity and crest displacements of the dam under three different hazard levels will be investigated.


Seismic analysis of concrete gravity dams
Akpınar, Uğur; Binici, Barış; Department of Civil Engineering (2019)
After the industrial revolution, energy has become one of the important issues determining the internal and external policies of the countries. Nowadays, to meet the energy needs of future generations and to reduce the damage to the environment, renewable energy sources are utilized. At this point, hydroelectric energy offers a clean and renewable energy source alternative. In addition to many built dams, the necessity of controlling existing dam stock punctuates the importance of studies on the seismic des...
Performance of concrete gravity dams under earthquake effects
Soysal, Berat Feyza; Arıcı, Yalın; Department of Civil Engineering (2014)
Concerns about the seismic safety of gravity dams have increased with the construction of numerous new dams in the developing world as well as the need for the evaluation of existing dam stock in the developed countries. The common procedure for the design of concrete gravity dams has been linear analyses: there is scant experience on the design of such systems using nonlinear analyses as the post-linear behavior and performance limits of gravity dam monoliths are not well known. This study is focused on th...
Seismic performance evaluation of roller compacted concrete gravity dams by pseudo dynamic testing
Aldemir, Alper; Binici, Barış; Department of Civil Engineering (2016)
The energy demands throughout the world have reached a level that could create irreversible impacts on the environment unless an overall energy policy to reduce the energy production relying on fossil fuels is implemented. The apparent effects of global warming enforced countries to take precautions and to set limits on the fossil fuel consumption. Thus, the renewable energy sources like hydropower, solar energy, biomass, etc. have, nowadays, been encouraged to generate electricity. Certainly, dams are exce...
Sustainable hydrogen production process development using reducible oxides
Çalışan, Atalay; Üner, Deniz; Department of Chemical Engineering (2020)
The energy demand is driven by increasing world population and living standards. Sustaining this demand with available and renewable energy sources is a major challenge. The options such as solar and wind power, are unreliable for a steady energy production due to their intermittent nature. Therefore, the storage of renewable energy, such as hydrogen, gains importance. In the scope of this thesis, a sustainability barrier in front of solar integrated hydrogen production processes was addressed in terms of m...
Seismic analysis of concrete gravity dams including damfoundation-reservoir interaction
Yücel, Ali Rıza; Binici, Barış; Department of Civil Engineering (2013)
The attractiveness of the hydroelectric power as a domestic, clean and renewable energy source increased with the rise of the energy demand within the last decade. In this context, concrete gravity dam construction gained a high momentum. Use of roller compacted concrete as a dam construction material became popular due to advantages such as reducing the construction duration and costs. Concrete gravity dams are special type of structures which requires an extensive care for their seismic analysis and desig...
