However, a drawback is its low modulus of elasticity compared to steel which results in early concrete cracking at lower service loads , as well as the lack of failure ductility in the flexural elements. The noncorrosive properties and the high strength-to-weight ratio of FRP reinforcement provide a perfect solution for optimized structures in aggressive environments. The use of Fiber-Reinforced Polymers (FRP) reinforcing bars in concrete structures is becoming more desirable as an alternative for steel reinforcement.

Reinforced Concrete Design By H J Shah Free If YouOne study suggested the use of ductile materials in the compression zone of critical sections at which the plastic hinge is likely to form as a way to improve the ductility of FRP-reinforced elements. Regarding the enhancements of ductility of FRP-reinforced members, many researchers focused on improvements in the compression zone.

Similarly, the fib-bulletin 40 recommends the use of a partial safety factor for FRP bars of 1.3 instead of the 1.15 factor recommended for steel reinforcement.Reinforced Cement Concrete (RCC) or Reinforced Concrete or Reinforced Concrete Design Standard Books PDF Free Download. A strength reduction factor ranging between 0.55 and 0.65 according to the failure mode is recommended by the ACI 440.1R-06 Standard.These elements are proposed to be designed as over-reinforced elements with the amount of FRP reinforcement more than that of steel reinforcement.Publisher : Charotar Publishing House Pvt. The latter authors recommended designing flexural elements in a way that ensures the failure is initiated by steel yielding, followed by concrete crushing and finally by the rupture of FRP bars. Another technique is to use additional steel bars in the FRP-reinforced elements to provide some ductility in the tensile zone. However, the use of these hybrid bars is associated to high manufacturing costs and, in case of using bars with more than one FRP layer, a gradual irreversible failure in the reinforced element due to the rupture of FRP layers. The most effective results were achieved by the use of hybrid reinforcement bars consisting of a steel core surrounded by multi-layers of FRP materials. Other researchers recommended the addition of polypropylene fibers to the concrete mix to improve the ductility of FRP reinforced elements. ![]() A value not lower than 0.8 can be achieved from the strength reduction factor, where sufficient moment redistribution is proven to take place at failure. This is achieved by adjusting the area of FRP and steel reinforcement along the beam.The strength reduction factors currently recommended by the codes for FRP-reinforced elements can be significantly improved where the approach discussed in this paper is adopted. Ultimately, the direct relationship between the stiffness ratio and the moment ratio can be plotted by comparing the two previously mentioned relationships.For this analysis, it is assumed that the effect of any bars in the compression zone at any section on the flexural stiffness is neglected.The use of FRP bars as reinforcement for concrete structures can be made more reliable through controlling their failure by adding a specific amount of steel bars buried inside the FRP cage in the critical sections, where plastic hinges are likely to form and adjusting the FRP reinforcement in the other sections to make them capable of taking over the additional moment redistributed from these hinges.The suggested design approach depends on finding a balance between the flexural capacity of the designed element and the safety margin maintained at failure.
