Comparative analysis of metal reinforcementand fibre-reinforced plastic rebar

Building constructions, buildings and structures

Today reinforced concrete is material most widely used in construction. Many manufacturers offer to reduce the cost of this product by replacing the steel reinforcement to the fiber-reinforced plastic bar. However the effectiveness of such replacement raises the question. The article provides a comparative analysis of metal reinforcement and fiber-reinforced plastic bar (FRP). The main characteristics for comparison were defined based on the analysis of national and foreign publications. As a result of this comparison advantages and disadvantages of FRP using were defined. The article also provides metal reinforcement on FRP replacement economic efficiency analysis. The research is accomplishing by list of constructions in which usingof FRP is more effective than metal reinforcement.
