This study comparatively evaluates the behavior of the flexural crack and diagonal crack of ultra-high performance fiber reinforced concrete beam containing coarse aggregate (UHPFRC-CA) under applied shear load. The beams were tested under four point loading arrangement to investigate the influence that shape of steel fiber, steel fiber volume (Vf) and shear span-depth ratio (a/d) have on their crack behavior. The results obtained from the study showed that decrease in a/d significantly incr...
This research assesses the capability of existing shear capacity equations to adequately predict the shear strengths/ultimate loads of ultra-high performance fibre reinforced concrete (UHPFRC) beams in order to check their level of accuracy and to determine the equation that can be reliably used to predict/design UHPFRC beams against shear loading. Influential shear variables like shear span-depth ratio (a/d), percentage volume of steel fibre (Vf), longitudinal tensile reinforcement ratio (ρ...
