Response of high-strength concrete beams with corrugated discrete steel fibers to small shear span-depth ratios

The behavior of high-strength, fiber-reinforced concrete (HSFRC) beams under concentrated loads was affected by many different aspects, such as the type fibers used and volume percent fibers; nevertheless, primarily modifying shear span-to-depth ratio (a/d). In this experimental investigation, influence a/d ratios (ranging from 1.5 to 2.2) is investigated on response twelve high-strength containing varying amounts discontinuous steel fiber (vf) in mixture. purpose study analyze manner failures tested identify a limiting for effective beam depth. Shear failure observed (HSRC) with vf 0% at high 2.2, according findings study. Altering either or had an effect way which HSFRC responded stimulus. Some that were put through shear–flexure test failed. addition, demonstrated that, increased up 0.5% 0.75% broke pure flexure multi-cracking. This indicates has substantial impact various behaviors beams.
