Abstract:Analysis of the experimental results obtained by testing 45 concrete specimens reinforced with fiber reinforced plastic (FRP) reinforcing bars is outlined. Theoretical correlations with experimental results are conducted in terms of elastic and ultimate bending moment, crack width, and bond and development length. Emphasis is placed on the beam bending analysis and design using regular as well as high-strength (4 to 10 ksi) concrete reinforced with FRP bars by modifying the state-of-the-art design per ACI 318-89 provisions applicable for steel reinforced beams. However, modifications (from the current ACI Building Code) for FRP reinforced beams in terms of ultimate moment capacity, crack pattern, and development length are made without deviating significantly from the design philosophy given in ACI 318-89. Equations for design loads and bending, resistance, bond and development lengths, and crack widths are developed in a simplified form for practical design applications. Similarities and parallels of these design equations with current ACI 318-89 equations are maintained when possible.
