Experimental Investigation of FRP-Concrete Hybrid Beams
(*) Corresponding author
On the basis of an experimental program, an investigation has been conducted, in order to study the behavior of reinforced concrete beams by fiber-reinforced polymers. For this purpose, two kinds of beams have been considered: a control beam and beams strengthened in flexure with fiber-reinforced polymers. The work investigated a variety of design, namely carbon and glass fabric reinforced polymer composite, and fabric reinforced polymer composite based on vegetable fiber. The series of the beams were subjected to three point loading test until failure. The structural performance of the sixteen beam specimens will be discussed on the following two aspects: (a) flexural ductility improvement; and (b) Failure load.
