Abstract :

Although the steel reinforcement in concrete structure is protected by concrete, aggressive environmental condition can stimulate the carbonation of concrete and the formation of hydrated ferrous oxide in steel, resulting in spilling of concrete cover. However, the use of fiber reinforced polymers (FRP) has become a subject of great interest in structural community. The aging of the nation’s infrastructure in a tight economic environment has necessitated the search for innovative and cost effective solutions, several studies have focused on the use of externally bonded FRP to strengthen existing structure although FRP are more expensive than traditional structure materials, the savings in labor and equipment costs associated with the use of FRP make them an attractive alternative for strengthening because of its corrosion resistance to environmental agents as well as the advantages of high stiffness - to -weight and strength – to –weight ratios when compared to conventional construction materials. Other advantages of FRP include low thermal expansion, good fatigue performance and damage tolerance, non –magnetic properties and easy to transport. This study was conducted to study and compare the behavior of reinforced concretebeams using different fibers (carbon fiber, fiberglass and basalt fiber) and exposed to static vertical load until the collapse. 2 - Fully supported beams using carbon fiber, basalt and glass fiber 3 - Beams supported and fixed with basalt fiber, these samples have been tested under the influence of concentrated loads to collapse and compare the different variables. The results in this study are aimed at the behavior of these beams is known under the influence of several factors and using different methods of consolidation. In this study we have compared the results of the tests carried out on the samples.
