The primary goal of this study was to examine the relative effects of various factors that affect the cracking of the face slab of a concrete faced rockfill dam (CFRD). Rigorous simulation of the construction and impoundment stages were conducted in sequential phases during which the rockfill and the rockfill-face slab interface were modelled with elasto-plastic models that were calibrated to existing test data. The face slab was modelled using embedded reinforcements with a total strain crack model. The results of the analyses showed that the stiffness of the rockfill significantly changed the crackwidth on the face slab, but not the extent of cracking. Increasing the reinforcement ratio was the most effective remedy for decreasing the average crack width on the slab. The properties of the rockfill-slab interface and the location of the reinforcement within the slab did not significantly affect the cracking on the slab.

Behaviour of CFRP confined low strength concrete columns under temperature changes Erdil, Barış; Akyüz, Uğurhan; Yaman, İsmail Özgür (2012-12-01) In this study, an experimental program was established to understand the behaviour of FRP-confined low strength cylindrical and square-section concrete columns under temperature changes. The experimental program was divided into four groups. First group of specimens were kept under room temperature and used as control specimens. In the second group, specimens were exposed to predetermined heating-cooling cycles in a specially designed environmental test chamber. Third group of specimens were placed in water...
Effects of short cracks on fatigue life calculations Kaynak, Cevdet; Baker, T.J. (1996-01-01) In this study, the potential impact of the short crack problem in En7A steel with a high content of elongated MnS inclusions has been observed. Experimental short crack data were compared first with the predicted S-N curves determined using long crack growth parameters and second with the calculated lives using only long crack data and using both short crack and long crack data. All these life predictions revealed that long crack data alone cannot be used in fatigue lifetime analyses that treat short crack ...
Stress strain behaviour of structural lightweight concrete under confinement Şenel, Mehmet Ali; Tasbahjı, Tayseer; Turanlı, Lutfullah; Sarıtaş, Afşin (null; 2015-12-11) : In this study, stress-strain behavior of structural lightweight concrete is studied under unconfined and confined conditions. To this end, the use of naturally occurring perlite material as lightweight aggregate and cement replacement material is considered. Although there are several studies on the confinement effects on normal weight concrete, there is lack of data on the confinement behavior attained for structural lightweight concrete by spiral or stirrup reinforcement. In order to evaluate the perfor...
Degradation of decabromodiphenyl ether (BDE-209) in microcosms mimicking sediment environment subjected to comparative bioremediation strategies Demirtepe, Hale; İmamoğlu, İpek (Elsevier BV, 2019-03-01) The aim of this study was to examine bioremediation strategies for BDE-209 contaminated sediments. Sediment microcosms were established to observe anaerobic debromination of BDE-209 under conditions representing three bioremediadon strategies: biostimulation, bioaugmentation and natural attenuation. To simulate biostimulation, a defined mineral medium containing both a carbon source (sodium formate) and electron donor (ethanol) was added into sediments. Bioaugmentation was established by enrichment of the s...
Evaluation of the performance of the face slab of a CFRD during earthquake excitation Arıcı, Yalın (Elsevier BV, 2013-12-01) The primary goal of this study was to examine the cracking behavior of the face plate of a CFRD during earthquake excitation. Analyses of the impounding stage and earthquake loading were conducted in sequential phases using a 2-D plane-strain model with the appropriate non-linear constitutive relationships for the dam constituents. The effect of rockfill stiffness and the face plate design properties on the seismic performance of the face plate was investigated. The crack widths on the plate increased with ...
