Development of a safetyinspection methodology for river bridges
Berk, Aysu; Yanmaz, Ali Melih; Department of Civil Engineering (2006)
River bridges get damaged or even collapse because of various reasons, such as development of adverse hydraulic conditions during severe floods, disastrous earthquakes, deficiencies in structural and geotechnical design, material deficiencies, or other unexpected external factors. Failure of service at vital lifelines, bridges, can lead to loss of several lives and properties, traffic disruption, and/or deficiencies in daily usage. Existing structures should be monitored periodically for decision-making and...
Evaluation of Scour Risk at Foundations of River Bridges
Yanmaz, Ali Melih; Çalamak, Melih (2016-07-01)
River bridges are exposed to more inconvenient conditions due to the structure-flow interaction compared to bridges having no contact with flow. Therefore, one of the most important components of the bridge failure risk is the risk induced by soil-flow interaction. In this study, the uncertainties of the hydrological and hydraulic parameters affecting the scouring around bridge piers are examined using appropriate probability density functions. In the analyses, the uncertainties involved in the temporal var...
Modeling temporal variation of scouring at dual bridge piers
Selamoğlu, Meriç; Yanmaz, Ali Melih; Köken, Mete; Department of Civil Engineering (2015)
Computation of temporal evolution of scour depth around bridge piers is essential for the efficient design of bridge pier footings. In this thesis, empirical scour-prediction equations and a semi-empirical model are developed to predict the temporal variation of maximum clear-water scour depth at dual cylindrical uniform piers with identical size in tandem arrangement. Experiments are conducted using different pier size, pier spacing, and flow intensities. The semi-empirical model is based on sediment conti...
Interaction between bridge abutment and piers concerning local scour
Akbulut, Ömer Faruk; Göğüş, Mustafa; Kökpınar, Mehmet Ali; Department of Civil Engineering (2020-8)
Flowing water usually causes transportation of loose non-cohesive materials, called sediment in literature, in natural open channels such as rivers and canals with a transportable material bed. This sediment transportation is observed in two different situations; deposition and erosion. Excessive erosion leads in scouring. Scouring can be classified in three groups; general, contraction and local scour. Scouring namely removal of bed material from bridge sites cau...
Hız-Doğruluk Fonksiyonlarının Modellenmesi
Kılıç Özhan, Aslı(2018-12-31)
Psikoloji araştırmalarında sıklıkla karşılaşılan engellerden biri katılımcıların hızlı cevap vermek için cevabın doğruluğundan ödün vermeleridir. Bu olgu, hız- doğruluk ödünümü (speed-accuracy tradeoff) olarak adlandırılmaktadır. Psikoloji deneylerinde gözlemlenen bu eğilimi anlamak ve kontrol etmek için sınırlı sürede cevap yöntemi kullanılmaktadır. Sınırlı sürede cevap yönteminde katılımcılardan cevaplarını bir sinyal sesi duyduktan veya ekranda bir sinyal gördükten sonra vermeleri istenir. Genellikle, ce...
