The application of fiber-reinforced polymer bars is rapidly rising in concrete structures because corrosion resistance and high tensile strength. By contrast, reinforced with FRP illustrate less ductility brittle failure without warning than conventional steel bars. Hybrid the combination can simultaneously increase strength ductility. This paper aims to estimate effective moment inertia hybrid...

The mechanic...

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...

Fiber-reinforced composites are an ideal high-performance composite material made from a combination of high-strength continuous fibers and polymer matrix. Compared to short cut fibers, long strand can improve the mechanical properties fiber more effectively. Herein, aramid fiber-reinforced PLA filaments with centering were prepared by modifying outlet design desktop-grade thermoplastic single-...

Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...

Abstract Fiber-reinforced polymer (FRP) has been commonly used to reinforce concrete structures. The kinds of FRP demonstrate an effective alternative various methods reinforcement in structures subjected bad environmental conditions which cause corrosion and damage concrete. Due their lightweight, high strength, fatigue resistance, Fiber Reinforced Polymer composites have widely applied steel ...

one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...
