Serviceability behavior of High Strength Concrete I-beams reinforced with Carbon Fiber Reinforced Polymer bars

Fiber Reinforced Polymer (FRP) bars are anisotropic in nature and have high tensile strength the fiber direction. The use of High-Strength Concrete (HSC) allows for better high-strength properties FRP bars. mechanical can yield to large crack widths deflections. As a result, design concrete elements reinforced with materials is often governed by Serviceability Limit States (SLS). This study investigates short-term serviceability behavior RC I-beams. Eight I-beams carbon-FRP (CFRP) four steel I-beams, comparison purposes, were tested under two-point loading. Deformations on spacing measured analyzed. A discussion main aspects SLS introduced. service load that fulfills requirements, at cross-section level, ranges between 0.27 0.38 times ultimate sections dimensioned fail crushing. determinant criterion deflection limitation
