AB  - This study examines the tensile fatigue behavior of Ultra-High Performance Concrete (UHPC) reinforced with steel and carbon fibers under cyclic loading. Three specimen types —un- reinforced matrix (BM), steel fiber-reinforced (SF), and carbon fiber-reinforced (CF)— were tested using indirect tensile static and fatigue methods with a modified Brazilian test setup. A hinge-based T-shaped loading mechanism ensured stable crack propagation, while strain monitoring combined localized strain gauges with full-field digital image correlation (DIC) for detailed crack behavior analysis. Results indicate tensile strength enhancements of 40% for CF and nearly 3 times for SF over BM. Crack initiation stresses were 7.5MPa (BM),…
