Pultruded frp profile as embedded reinforcement for reinforced concrete columns

The advent of concrete at the beginning of the last century made possible structures in which two complementary materials, concrete and steel, were able to offer compressive and tensile resistance to structural elements. Now new composition have been explored, improving the resistance and the stiffness of the structures by using embedded steel profiles in concrete, and such a type of structural elements are increasing, offering better performance in term of resistance, stiffness. The reinforced concrete shows that presence of steel brings the problem of corrosion, which results in damaging the concrete with side effect like spalling of the cover, shortening the life of the structure and bringing higher maintenance costs. In recent years greater interest has been directed towards the FRP (Fiber reinforcement polymers) structural elements and new types of reinforcement. In this work experimental numerical analysis of compressive/bending behavior of FRP pultruded profiles embedded in reinforced concrete has been introduced. The paper shows some comparison between FRP-concrete composite columns, traditional reinforced concrete, and steel profile concrete embedded columns.
