This guide is based on the knowledge gained from worldwide experimental research, analytical work, and field applications of FRP reinforcement.
Fiber-reinforced polymer (FRP) materials have emerged as an alternative material for producing reinforcing bars for concrete structures. FRP reinforcing bars offer advantages over steel reinforcement in that FRP bars are noncorrosive, and some FRP bars are nonconductive.
Due to other differences in the physical and mechanical behavior of FRP materials versus steel, unique guidance on the engineering and construction of concrete structures reinforced with FRP bars is needed. Other countries, such as Japan and Canada, have established design and construction guidelines specifically for the use of FRP bars as concrete reinforcement.
