Research ArticleOpen accessIn the keywordsChloride Penetration Resistance Studies on Concretes Modified with Alkali Resistant Glass FibersK. Chandramouli, P. Srinivasa Rao, N. Pannirselvam et al.Problem statement: This research study presented the durability performance of glass fibre reinforced concrete. Approach: The influence of fiber content on the durability performance of glass fibre reinforced concrete specimens having different percentage of glass fibres with varying grades of concrete were investigated. Results: The parameter of investigation included rapid chloride permeability test for a period of 365 days. Specimens … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Confinement on the Axial Performance of Fibre Reinforced Polymer Wrapped RC ColumnA. Rajasekaran, P.N. Raghunath, K. SugunaThe combined effect of internal steel ties and external FRP wrap was investigated using nine reinforced concrete columns with varying thickness of external wrap. The load, deflection and lateral expansions were studied at yield state and ultimate state. The results from the experimental investigations were used for performing a multi-variate linear regression analysis incorporating the contribution of tie spacing as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,570 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBehavior 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
EditorialOpen accessIn the keywordsEditorial for the "FRP Structures" Special IssueFabio Minghini, Chiara Bedon, Francesco Ascione, John Kaiser CalautitThe objective of this Special Issue is to present recent advances and emerging cross-disciplinary in the field of thin-walled composite profiles made of Fiber Reinforced Polymers (FRP), as well as the use of FRP components in structural engineering in general. In this Editorial, a brief summary is provided for all the published papers, in order to emphasize the wide range … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 7,924 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUse of Recycled Aggregate and Fly Ash in Concrete PavementMyle Nguyen James, Wonchang Choi, Taher Abu-LebdehProblem statement: Recycled materials aggregate from the demolished concrete structures and fly ash from burning coal shows the possible application as structural and non structural components in concrete structures. This research aims to evaluate the feasibility of using concrete containing recycled concrete aggregate and fly ash in concrete pavement. Approach: Two water cement ratio (0.45 and 0.55) the compressive strength, … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 9,315 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquivalent Torsional-Warping Stiffness of Cores with Thin-Walled Open Cross-Section Using the Vlasov Torsion TheoryTriantafyllos Konstantinos MakariosIn order to calculate the equivalent torsional-warping stiffness of the Reinforced Concrete (RC) cores that have thin-walled open cross-section, a new analytical methodology, which combines the Vlasov torsion theory with the Bernoulli bending theory, is presented herein. As the basis of the calculations, we use the principal elastic reference system of the core from this we consider that is known. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 2 · 23 May 2023 · 6,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecision Making and Predicting the Cost for the Optimal Structural System of Multi-Story BuildingsHosam Elhegazy, Ahmed Ebid, Ibrahim M. Mahdi et al.There are numerous structural lateral systems used in multi-story buildings design such as the shear wall, frame system, framed with core, dual systems and superframes, etc. Additionally, the system of slabs such as (Solid Slab, Flat Slab, Flat plates, Hollow blocks, ... and Waffle Slabs). Generally, the structural systems of multi-story buildings are considered to be different types.
