Evaluation of the Ultimate Strength of the Ultra-High-Performance Fiber-Reinforced Concrete Beams

Evaluation of the ultimate strength for UHPFRC (ultra-high-performance fiber-reinforced concrete) flexural members was conducted. In this study, an experimental program about beams conducted with effect fiber volume fraction, shear span to depth ratio, and compressive matrix as main variables. Among them, it found that fraction variable had greatest influence on strength. The inclusion 2% steel increases significantly. particular, changed mode failure from diagonal into failure. For classification patterns, were evaluated using current design code UHPC guidelines. Flexural affected by size shape stress block consideration matrix’s tensile accurate prediction beams, high should be considered.
