Research ArticleOpen accessIn the keywordsStrength Modeling of High-Strength Concrete with Hybrid Fibre ReinforcementA. Ravichandran, K. Suguna, P. N. RagunathThe low tensile strength and limited ductility, the unavoidable deficiency, of concrete can be overcome by the addition of fibres. High strength concrete (HSC) of 60 MPa containing hybrid fibres, combination of steel and polyolefin fibres, at different volume fraction of 0.5, 1.0, 1.5 and 2.0% were compared in terms of compressive, splitting tensile strength and flexural properties with HSC … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,541 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStrength 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

Research ArticleOpen accessIn the abstractDuctility Performance of Hybrid Fibre Reinforced ConcreteS. Eswari, P.N. Raghunath, K. SugunaThis study presents a study on the ductility performance of hybrid fibre reinforced concrete. The influence of fibre content on the ductility performance of hybrid fibre reinforced concrete specimens having different fibre volume fractions was investigated. The parameters of investigation included modulus of rupture, ultimate load, service load, ultimate and service load deflection, crack width, energy ductility and deflection ductility. … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,290 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPre-Reinforcement Sprinkle FRP for Reinforced-Concrete Beams against Earthquakes, FRP: Consumption in Civil EngineeringMoein Zargar, Hossein Gholami, Hossein Norouzi et al.Nowadays, the reinforcement is used by green concrete, coated steel sheet, reinforcement, fiber reinforced such as carbon, aramid, and glass as earthquake reinforcement methods for concrete structures. regard the reinforcing structures and buildings against earthquake forces in the future, only simple methods for lowering prices should not be considered and the earthquake behaviors should be completely transparent. In this article, … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 26 Jun 2019 · 7,344 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffect 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

Research ArticleOpen accessAll words, across the recordNeural Network for Performance of Glass Fibre Reinforced Polymer Plated RC BeamsN. Pannirselvam, P.N. Raghunath, K. SugunaPrediction of the properties other than moment carrying capacity of GFRP plated RC beams does not have any straight forward mechanism. This study presents a General Regression Neural Network (GRNN) based computational model for predicting the yield load, ultimate load, yield deflection, ultimate deflection, deflection ductility and energy ductility of such beams. Results from experimental investigations carried out on nine … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,329 accessesView PDF Cite
