Su kaynaklarının verimli kullanılmasında en önemli yapılar barajlardır. Barajların, sismik etkiler altındaki davranışları deprem mühendisliğinde karşılaşılan en karmaşık problemlerden birisidir. Ülkemizde son yıllarda tercih edilen en önemli baraj tipi silindirle sıkıştıtılmış beton barajdır. Beton ağırlık barajların sismik davranışı laboratuvar ortamında birkaç sarsma tablası testi dışında deneysel olarak fazla incelenememiştir. Bu çalışma ile literatürde ilk defa dinamik benzeri deney yöntemi ile ölçekli baraj deneyleri gerçekleştirilmiştir. Çalışma kapsamında üç adet numunesi ardışık etki eden üç farklı deprem kaydı altında denenmiştir. Bu numunelerden ikisi farklı çekme dayanımlarına sahip SSB’den ve diğer numune ise geleneksel beton kullanılarak üretilmiştir. Tüm numuneler Türkiye’de tasarlanan en yüksek SSB baraj olan Melen Barajının 1/75 ölçekli halini yansıtmaktadır. Deneysel sonuçlar Türkiye'de tasarlanan en yüksek SSB ağırlık barajlardan birisinin sismik performansı hakkında da değerli deneysel veriler temin edilmesini sağlamaktadır. Ayrıca, baraj sismik performans belirlemesinde sıklıkla kullanılan nonlineer sonlu eleman modelleri ile gözlemlenen hasarın ne ölçüde tahmin edilebileceği de sunulmuştur.

A study on the reliability-based safety analysis of hardfill dams Kitapcıgil, Sülen Nur; Yanmaz, Ali Melih; Kentel Erdoğan, Elçin; Department of Civil Engineering (2010) Dams are important large structures providing vital benefits to human life. These strategic structures are necessary in order to supply water and energy and to control floods. Moreover, dams have important roles in regional development and national economy. Thus, the design of dams deserves rigorous studies. Deterministic approach may be acceptable for design of dams and may satisfy safety requirements if large safety factors are used. However, such an approach will not be cost-effective in economic terms. ...
Ground motion scaling for the prediction of the seismic response of concrete gravity dams Duygu, Mustafa Berk; Arıcı, Yalın; Department of Civil Engineering (2014) Designing dams for seismic safety gains importance as the number of dams are increasing as a result of increasing need in water storage and hydropower. To define a structure’s seismic safety, scaling of accelerograms should be considered as one of the most crucial elements. Appropriate scaling of ground motion records is required to better estimate the linear and nonlinear structural response of a structure. Although, in literature, there exist numerous methods dealing with this issue, it is required to det...
Characterization of groundwater and surface water interaction in kirmir stream using thermal remote sensing and in-stream measurements Varlı, Dilge; Yılmaz, Koray Kamil; Department of Geological Engineering (2016) Effective management of water resources requires understanding and quantification of interaction between groundwater and surface water bodies. The exchange processes have recently received increasing attention because also they have important influences on ecological status of watersheds. The purpose of this study was to characterize the interaction between surface water - groundwater in Kirmir stream - a controlled stream nearby Kızılcahamam, Ankara, Turkey. At the first stage, stream reaches with interact...
Hydraulic characteristics of tyrolean weirs having steel racks and circular-perforated entry Şahiner, Halit; Göğüş, Mustafa; Department of Civil Engineering (2012) Tyrolean type water-intake structures are commonly used on mountain rivers to supply water to hydropower stations. The amount of water to be diverted from the main channel is the major concern in these kind of structures and should not be less than the design discharge. In this study a physical model of a Tyrolean type water-intake structure was built at the laboratory and the diverted flow from the main channel through the intake structure having steel racks and perforated plates of different types were me...
Design of settling basins and related problems encountered in practice Zaloğlu, Fatma Deniz; Göğüş, Mustafa; Department of Civil Engineering (2013) Settling basins are the hydraulic structures used to get sediment-free water from rivers mostly for hydropower systems. Mainly fine sediment is trapped along the settling basins and from time to time the accumulated sediment in the settling basin is flushed away. A wrong design of a settling basin creates lots of problems. In this study based on the hydraulic analysis of a settling basin, the available settling basin design procedures in the literature were reviewed. Some of the settling basins constructed ...
