Research ArticleOpen accessIn the abstractEffect of Corrosion Damage on the Ductility Performance of Concrete ColumnsJ. Revathy, K. Suguna, Juan Eduardo Suarez RivadeneiraProblem statement: An experimental investigation was carried out on reinforced concrete columns with corroding reinforcement to assess the residual strength and ductility performance of columns. Approach: An accelerated corrosion regime of different degrees of corrosion damage of 10 and 25% were induced in the steel reinforcement of concrete columns. The columns were then tested under uni-axial compression until failure. Results: … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength 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 · 7,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Serviceability Considerations of HSC Heavily Steel Reinforced Members under BendingAli Akbar Maghsoudi, Yasser SharifiTo investigate the serviceability conditions of High Strength Concrete (HSC) beams, the total number of 6 beams (L = 2 m, b = 0.2 m, h = 0.3 m) heavily reinforced with different ratios of ρ and ρ' were cast and tested under bending load. During the test the concrete and steel strains, deflection and crack width are measured at … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Three Dimensional RC Infilled Frame - RC Plane Frame Interactions With Slab for Seismic ResistanceSuyamburaja Arulselvan, K. SubramanianExperimental investigation was planned and conducted to study the influence of brick masonry infill and slab in a three-dimensional reinforced cement concrete frame. In this study, one-fifth scale 3D R.C frame representing single story, three bays with central bay brick infill at the sides and a long single bay without infill in the middle of the frame along loading direction … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Models and Experimental Investigation of Lifetime History of HSC Flexural BeamsK. Masti, A.A. Maghsoudi, R. RahgozarThe nature of fracture in high strength concrete is brittle and therefore, the investigation behavior of flexural high strength concrete (HSC) members is important. This paper describes the deflection, strain and energy ductility and the lifetime history of experimental and theoretical analysis of six caste reinforced HSC beams with different percentage of ρ and ρρ'. The beams were loaded incrementally … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 6,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Optimization of Composite I Beam Floor SystemUroš Klanšek, Stojan KravanjaThe paper presents the cost optimization of the composite I beam floor system. The composite I beam floor system is designed to be constructed up of a reinforced concrete slab and doubly-symmetrical welded steel I beams. The optimization was performed by the nonlinear programming approach, NLP. An accurate objective function of the manufacturing material, power and labour costs was developed … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element and Experimental Serviceability Analysis of HSC Beams Strengthened with FRP SheetsSeyed Hamid Hashemi, Reza Rahgozar, Ali Akbar MaghsoudiThe use of externally bonded composite sheets or laminates is by now a diffuse technique to strengthen existing RC structures. However, some aspects of flexural condition still need experimental and numerical analysis; furthermore, especially for serviceability checks, there is a lack of code provisions. Six reinforced high strength concrete (HSC) beams strengthened with FRP sheets were fabricated and tested, the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,445 accessesView PDFCite
