Research ArticleOpen accessIn the abstractEffects of Different Environments on Reinforcement Concrete CorrosionMohammed Thalji Awwad, Omar Asad AhmadThis research focuses on various forms of steel bar corrosion located in different environments and the factors affecting the corrosion process, both the external (surrounding environment around concrete elements) and the internal environment (concrete itself), as well as on the investigations and tests for this type of damage, in order to develop measurements and recommendations that will reduce harmful investment … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 15 Sep 2017 · 7,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractCracking of Reinforced Recycled Concrete SlabsFlavio Stochino, Luisa Pani, Lorena Francesconi, Fausto MistrettaThe results of an experimental investigation on cracking of fifteen reinforced recycled concrete slabs are presented in this paper. Five different recycled aggregates replacement percentages have been used for different mix design. First, the values of tensile strength, cylindrical compressive strength and modulus of elasticity of the concrete mixes have been determined. Then the deflection-load curve of the simply supported … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 1 · 5 Sep 2017 · 10,162 accessesView PDFCite

Research ArticleOpen accessIn the abstractPrediction of Residual Axial Load Carrying Capacity of Reinforced Concrete (RC) Columns Subjected to Extreme Dynamic LoadsMasoud Abedini, Azrul A. Mutalib, Sudharshan N. Raman et al.The evaluation of residual axial load carrying capacity of Reinforced Concrete (RC) columns to explosion load is significant for protection of buildings. The few investigations conducted on residual axial load carrying capacity of RC columns when subjected to blast loads. Therefore, the overall aim of this research is to generate equations on the blast capacity of axially and uniaxial loaded … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 May 2017 · 8,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractBehavior of Lightweight Coarse Aggregate RC Beams with Circular OpeningAdel A. Al-AzzawiThis pressent research investigates the mechanical properties of Waste Rubber Fibers Lightweight Coarse Aggregate Concrete (WRFLWAC) mixture. Also, the shear behaviors of 12 RC beams contain opening are investigated. The main study parameters are: The opening location, the waste rubber fiber ratio and the shear reinforcement. Deflection values and cracks are registered at each load step; also the cracking or … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 1 Apr 2017 · 7,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Objective Optimization of FRP Jackets for Improving the Seismic Response of Reinforced Concrete FramesCorrado Chisari, Chiara BedonIn this study, a multi-objective Genetic Algorithm (GA) optimization procedure is proposed for the seismic retrofitting of Reinforced Concrete (RC) building frames via Fiber-Reinforced Polymer (FRP) jackets. The optimization problem is solved via numerically efficient but accurate Finite-Element (FE) models able to take into account the strengthening and ductility increase contribution for a given FRP jacketing configuration. Based on a … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractFresh Water Savings Through the Use of Municipal Effluents in Concrete PavementBenard Chola, Stephanie Luster-Teasley, Manoj K. Jha, Miguel PicornellWastewater reuse presents a promising solution to the growing pressure on the world’s water resources. The use of municipal wastewater effluents for concrete production in the construction industry would result in energy and water savings leading to conservation and sustainability of our water resources.
