The effect of non divergence-free velocity fields on field scale ground water solute transport
(Springer, 2006)Solute plume subjected to field scale hydraulic conductivity heterogeneity shows a large dispersion/macrodispersion, which is the manifestation of existing fields scale heterogeneity on the solute plume. On the other hand, ... -
The effect of polypropylene fibers on asphalt performance
(Pergamon-Elsevier Science LTD, 2008)Polypropylene fibers are extensively used in civil engineering applications for many years. These fibers are used in concrete as a three-dimensional secondary reinforcement. Due to adhesion between polypropylene fibers and ... -
Effect of Pozzolan Content and Fineness on Early Hydration of Interground Blended Cements
(Japan Concrete Inst, 2014)The chemical composition and heat evolution of <45 mu m (fine), and > 45 mu m ( coarse) portions of interground, natural pozzolan-blended cements were investigated. Cements with four different pozzolan contents were ground ... -
Effective flexural rigidities for ordinary reinforced concrete columns and beams
(Wiley-Blackwell, 2014)Current effective flexural rigidities proposed for use in design and analyses of reinforced concrete structures have been examined. The level of accuracy in the estimation of section rigidity plays a very important role ... -

(Techno-Press, 2018)This study aims at evaluating the performance of repairing technique with CFRPs in recovering cyclic performance of damaged columns in flexure in terms of structural response parameters such as strength, dissipated energy, ... -
Effects of Compaction Method and Aggregate Properties on Mechanical Behavior of Granular Base Layer
(Turkish Chamber Civil Engineers, 2013)The aggregate properties and their compaction degrees are the two most important factors that have significant effects on the design of granular highway base layers. The effects of impact compaction and vibratory compaction ... -
Effects of Crumb Rubber Size and Concentration on Performance of Porous Asphalt Mixtures
(Hindawi Publishing Corporation, 2013)The purpose of this study is to investigate the effect of size distribution and concentration of crumb rubber on the performance characteristics of porous asphalt mixture. The recycling of scrap tires in asphalt pavements ... -
Effects of elevated temperatures on properties of concrete
(Elsevier Sci LTD, 2007)Concrete material in structures is likely exposed to high temperatures during fire. The relative properties of concrete after such an exposure are of great importance in terms of the serviceability of buildings. This paper ... -
Effects of Lead Core Heating on the Superstructure Response of Isolated Buildings
(Asce-Amer Soc Civil Engineers, 2017)Strength of lead rubber bearings (LRBs) deteriorates as a function of temperature rise in the lead core under cyclic motions. Accordingly, the isolator exhibits a gradual change in its hysteretic behavior that affects both ... -
Electricity from thermal and hydropower sources in Turkey: Status and future direction
(Taylor & Francis Inc, 2004)In 1995, electricity production reached 862 TWh, while in 1971 it was only 8.6 TWh. Electricity production is expected to reach 304 TWh by 2010. The sharp growth of the energy sector has been accompanied by institutional ... -
Electricity generation from existing multipurpose dams in Turkey
(Multi Science Publ Co LTD, 2005)The aim of this article is to investigate the hydropower potential of multipurpose dams constructed with the purpose of supplying irrigation, domestic water supply, flood control, navigation, recreation, sanitation, and ... -
Electricity production opportunities from multipurpose dams (case study)
(Pergamon-Elsevier Science LTD, 2007)The hydropower is the leading source of renewable energy. It provides more than 97% of all electricity generated by renewable sources. The main advantage of hydro systems is elimination of the cost of fuel. Hydropower on ... -
Energy from renewable sources inTurkey: Status and future direction
(Taylor & Francis Inc, 2004)Turkey is an energy importing country. Turkey's indigenous energy sources are limited and the country is heavily dependent on the import of primary energy from abroad. More than half of the energy requirement has been ... -
