Research ArticleOpen accessEvery word in the titleMulti-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 · 8,825 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAnalytical Study of Bending Behavior for Concrete Beams with T-Shaped Cross Section using Composite and Steel BarsSeyedeh Zahra Hosseini Ghaziyani, Seyedamin Mostafavian, Meysam Azizpour ChiraniTodays, instead of steel reinforcements, Fiber Reinforced Polymer (FRP) rebars have been using in the reinforced concrete structures. By consideration of different strain-stress behavior between steel and composite material, it is necessary to evaluate the difference of these two materials inside of RC beams. In this research, twelve reinforced concrete T-shape beams were modeled using ABAQUS finite element software. Six … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 2 Jun 2018 · 8,535 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsReliability of Axially Loaded Fiber-Reinforced-Polymer Confined Reinforced Concrete Circular ColumnsVenkatarman Nagaradjane, Pulipaka Narasimharao Raghunath, Kannan SugunaMonte-Carlo simulation based procedure was applied for assessing the reliability of Fiber Reinforced Polymer (FRP) confined reinforced concrete columns. Assessment of reliability provides a quantitative measure of effectiveness of repair. Problem Statement: The procedure presented in the paper could be used for assessing the reliability of reinforced concrete columns before and after the application of FRP wrap, thus helping to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2009 · 7,974 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStrength Modeling of Reinforced Concrete Beam with Externally Bonded Fibre Reinforcement Polymer ReinforcementN. Pannirselvam, P.N. Raghunath, K. SugunaThis research study presents the evaluation of the structural behaviour of reinforced concrete beams with externally bonded Fibre Reinforced Polymer (FRP) reinforcements. Three different steel ratios with two different Glass Fibre Reinforced Polymer (GFRP) types and two different thicknesses in each type of GFRP were used. Totally fifteen rectangular beams of 3 m length were cast. Three rectangular beams were … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,480 accessesView PDF Cite

Approach: A total of 21 beams specimens of size 150, 250×3000 mm were cast and tested. Results: Out of the 21 specimens, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,084 accessesView PDF Cite

Review ArticleOpen accessIn the abstractSeismic and Thermal Retrofitting of Masonry Buildings with Fiber Reinforced Composite Systems: A State of the Art ReviewArnas Majumder, Flavio Stochino, Fernando Fraternali, Enzo MartinelliOld masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. This study presents a literature review of the approaches currently available for masonry retrofitting. Specifically, it highlights … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 22 Feb 2021 · 11,961 accessesView PDF Cite

Research ArticleOpen accessIn the abstractConcretes Resistance of Yam a Great PersistenceHossein Gholami, Majedeh Haeri-Hamedani, Mohsen Ghane, Kaveh Ostad-Ali-AskariToday all distinguish the position of earthquake withstanding of constructions in seismic-vulnerable zones. With respect to this opinion that current concrete constructions are usually considered and constructed depend on earliest rules lacking examining the result of seismic powers and the novel rules don’t guess any shake, so, these structures must be persistence capability.

Research ArticleOpen accessIn the abstractEffect 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 · 7,566 accessesView PDF Cite
