This study evaluates the fracture properties and rear-face strain distribution of nonreinforced and hooked steel fiber-reinforced concrete panels penetrated by projectiles of three different nose shapes: sharp, hemispherical, and flat. The sharp projectile nose resulted in a deeper penetration because of the concentration of the impact force. Conversely, the flat projectile nose resulted in sha...

Enhancement of strength and ductility is the main reason for the extensive use of FRP (fiber reinforced polymer) jackets to provide external confinement to reinforced concrete columns especially in seismic areas. Therefore, numerous researches have been carried out in order to provide a better description of the behavior of FRP confined concrete for practical design purposes. This study present...

in the present study, modelling and vibration analysis of carbon nanotubes/ fiber/ polymer composite microplates are investigated. the governing equations of the carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. the modified couple stres...

This paper aims to study the permeability of High-Performance Concrete containing natural pozzolan and reinforced with fibers in high concentration sodium chloride solution. Optimized finely ground was employed as 6% partial substitution cement. Polypropylene 6 mm 12 lengths were introduced individually for a volume fraction 0.1% 0.15% respectively. Then, combination total fiber content 0.25%. ...

Concrete-filled fiber-reinforced polymer tubes (CFFTs) have attracted interest for their structural applications in corrosive environments. However, a weak interfacial strength between the fiber-reinforced polymer (FRP) tube and the concrete infill may develop due to concrete shrinkage and inadequate concrete compaction during concrete casting, which will destroy the confinement effect and ther...

high performance fiber reinforced cementitious composite (hpfrcc) materials exhibit strain hardening behavior with multiple cracking under tensile loading. in this paper, experimental and parametric studies are performed to assess the influence of using hpfrcc material instead of normal concrete in reinforced concrete beams. after calibrating the experimental results, the analytical results inc...

Abstract This study investigates the influence of steel and polyester fibers on mechanical durability properties steel–polymer hybrid fiber reinforced concrete (HyFRC) toughness under indirect tensile loading conditions. Steel Polyester are used as a single type (FRC) in combination an M45 grade composite with addition fly ash silica fume supplementary cementitious material. exhibited 10% impro...

SIFCON is characterized as a construction material of high ductility and very strength. It suitable for concrete structures used special applications. However, the density much higher than that Fiber Reinforced Concrete (FRC) due to need large amount high-density steel fibers. This work examines split tensile behavior modified weight slurry infiltrated fiber utilizing mixture two types fibers, ...

The natural fiber reinforced composites are being used in various fields of applications that are contributing to the replacement of synthetic fibers composites which consists of Boron, glass fiber, carbon fiber etc.. The composite natural fibers are being used due its light weight, higher specific strength and eco friendly natural, non –abrasive which also have economical value. As they are ma...
