Flexural Strength and Ductility Improvement of NSC beams
In order to calculate the flexural strength of normal-strength concrete (NSC) beams, the nonlinear actual concrete stress distribution within the compression zone is normally replaced by an equivalent rectangular stress block, with two coefficients of α and β to regulate the intensity and depth of the equivalent stress respectively. For NSC beams design, α and β are usually assumed constant as ...
متن کاملFlexural Testing of High Strength Reinforced Concrete Beams Strengthened with CFRP Sheets
The objective of this study is to investigate the effectiveness of externally bonded CFRP sheets to increase the flexural strength of reinforced high strength concrete (HSC) beams. Four-point bending flexural tests to complete failure on six concrete beams, strengthened with different layouts of CFRP sheets were conducted. Three-dimensional nonlinear finite element (FE) models were adopted by A...
متن کاملFlexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections
The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...
متن کاملInfluence of High Temperatures on Flexural Strength of Foamed Concrete Containing Fly Ash and Polypropylene Fiber
In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
متن کاملDuctility of Confined Concrete
Are structural engineers designing concrete structures with greater capacity and safety than they realize? By exploring effects of confinement in order to incorporate them in usual design procedures of engineering consulting companies, concrete structures will possibly in the future be both stronger, thinner and have a greater ability to deform prior to failure – three properties that are highl...
