dc.description.abstract | Shear behavior of a reinforced concrete (RC) beam designed without transverse reinforcement is significantly influenced by the properties of concrete. This paper investigates the effect of fly ash incorporation as 20 and 30% of the total binder content in 100% recycled aggregate concrete (RAC) beams designed without stirrups. To achieve greater packing density with higher aggregate proportions, particle packing mixture design was employed. Load-deflection diagram, load-strain diagram, and crack distri- butions with critical crack formations were examined to study the shear contributing mechanisms in RAC beams. Natural aggregate concrete (NAC) equivalent failure shear (within 10% variation) was obtained at low tension reinforcement percentage (ρ). However, 30% fly ash substituted RAC beams showed significant reduction in shear (approximately 20%) at high ρ. Applicability of shear resistance predictions of major standards (for NAC) to RAC beams are confirmed for the condition of low shear span-depth ratio and high ρ | en_US |
