This　article　experimentally　and　numerically　investigated　the　flexural　behavior　of　T-shaped　UHPFRC　beams　reinforced　with　high-strength　bars.　A　total　of　five　beams　were　tested　to　study　the　effect　of　steel　fiber　volumetric　ratio,　longitudinal　reinforcement　ratio,　and　mix　proportion　of　UHPFRC.　Test　results　indicate　that　flexural　stiffness　and　strength　increased　with　increasing　reinforcement　ratio,　while　the　effect　of　mix　proportion　was　negligible.　With　the　same　shear　reinforcement　ratio,　the　failure　mode　of　T-shaped　beams　changed　from　shear　failure　to　flexural　failure　with　steel　fibers.　Results　from　finite　element　analyses　had　good　agreement　with　test　results.　Future　research　will　focus　on　the　parametric　study　based　on　calibrated　finite　element　models　and　the　secondary　development　of　ABAQUS　to　simulate　the　shear　failure　of　UHPFRC　beams.　©　2021　fib.　International　Federation　for　Structural　Concrete
