This research presents an experimental investigation into the flexural behavior of High Performance Concrete (HPC)
beams incorporating varying volumes of hooked-end steel fibers. While HPC exhibits excellent compressive strength and durability, its brittleness under flexural loading is a key limitation. To address this, steel fibers were introduced at volume fractions of 0%, 0.5%, 1.0%, and 1.5%, and twelve beam specimens were tested under four-point bending following ASTM C1609/C1609M standards. The study evaluated critical parameters including first crack load, ultimate load, load-deflection characteristics, crack propagation, and failure mode.Results indicate that the inclusion of steel fibers significantly enhances flexural strength, ductility, and energy absorption capacity. Beams with 1.5% fiber content showed a 45% increase in peak load and a threefold increase in ultimate deflection compared to control specimens. Crack control also improved, with multiple fine cracks forming instead of a single wide crack. The mode of failure changed from brittle to ductile with increasing fiber dosage. These findings demonstrate the effectiveness of steel fibers in transforming HPC into a more resilient and flexure-tolerant material, making it suitable for critical structural applications such as earthquakeresistant buildings, bridge decks, and precast elements.
