Combining various kinds of fibre to achieve good response and strength from the concrete by using different experiments is shown in this research. Here PVA which polyvinyl alcohol HS hooked end steel fibres are used gain more compared with normal or single concrete. first we take specimens results considering optimum dosage 0.15% result & taken as HFRC can control crack behavior occurred sp...

This 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...

This paper deals with the effect of fiber aspect ratio of steel fibers on shear strength of steel fiber reinforced concrete deep beams loaded with shear span to depth ratio less than two using the artificial neural network technique. The network model predicts reasonably good results when compared with the equation proposed by previous researchers. The parametric study invol...

This report presents the results of an experimental study that was conducted to investigate the effects of key parameters on the compressive behavior of fiber reinforced polymer (FRP)concrete-steel double-skin tubular columns (FSDT). Hybrid FSDT columns have been introduced as a new form of hybrid columns. They consist of an outer tube made of FRP and inner tube made of steel, with sandwiched c...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

Concrete is a brittle material due to its poor tensile strength; consequently, concrete tends crack or peel under an applied external load. Previous studies have investigated the effect of incorporating fiber into concrete, which can improve strength. In this study, static and dynamic mechanical characteristics three types fiber-reinforced (FRC) were examined: carbon-fiber-reinforced (CFRC); Ke...

In this study, twenty glass fiber reinforced polymer (GFRP) reinforced concrete specimens were modelled using finite element method to predict the effect of GFRP compressive bars on the flexural strength and ductility of GFRP reinforced concrete beams. Also, the contribution of GFRP longitudinal rebars to the load-carrying capacity of reinforced concrete columns is determined. The concrete elas...

The huge quantity of concrete is consumed by the construction industry all over the world, probably second largest after water. In India, the conventional concrete is produced by using natural sand from riverbeds as fine aggregate. Dwindling sand resources poses the environmental problem and hence government restrictions on sand quarrying resulted in scarcity and significant increase in its cos...
