Flexural Performance of UHPC Beams Reinforced with BFRP Bars
This research addresses the performance of ultra-high-performance concrete (UHPC) reinforced with BFRP bars. Two BFRP reinforced UHPC beams with a cross-section of 185 mm × 250 mm and a total length of 2200 mm were cast and tested for flexure under a displacement-controlled loading condition. Two different reinforcement ratios were considered for this study such that one beam was designed as an “over-reinforced” section and the other beam was designed as an “under-reinforced” section. The experimental results were presented and discussed in terms of cracking moments, cracking pattern, failure modes, flexural capacity, midspan deflection, as well as strains in concrete and reinforcement. It was shown that the use of UHPC enhanced the flexural performance of BFRP reinforced beams in terms of moment capacity, deflection response and cracking patterns. The experimental results were complimented with analytical results that were calculated using the ACI 440 and CAN/CSA S806 code provisions. The nominal moment predictions using relevant ACI equations were found to be acceptable for the under-reinforced beam but slightly unconservative for the over-reinforced beam.
