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...
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...
Life cycle assessment of off-highway trucks and belt conveyors for sustainable mining Erkayaoğlu, Mustafa; Demirel, Nuray; Department of Mining Engineering (2011) In recent years increasing growth rate of all industrial fields generated an emerging energy demand and consequent environmental problems worldwide. Defining environmental profiles of products and systems using environmental tools, such as Life Cycle Assessment (LCA), is a critical issue for sustainable mining. In order to tackle the increasing environmental challenges and air emissions induced by surface coal mining, alternative material handling options are needed to be evaluated. This research study aims...
A review of renewable energy sources, sustainability issues and climate change mitigation Owusu, Phebe Asantewaa; Asumadu-Sarkodie, Samuel (2016-01-01) The world is fast becoming a global village due to the increasing daily requirement of energy by all population across the world while the earth in its form cannot change. The need for energy and its related services to satisfy human social and economic development, welfare and health is increasing. Returning to renewables to help mitigate climate change is an excellent approach which needs to be sustainable in order to meet energy demand of future generations. The study reviewed the opportunities associate...
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...
