The shear crack width, crack behavior, and crack development of 24 reinforced concrete beams have been experimentally investigated. All the beams reinforced with longitudinal reinforcement and hooked‐end steel fibers in place of transverse reinforcement. Hooked‐end steel fibers 35 and 60 mm long are used at volume fractions ranging from 0.75% to 1.5% in the first case, and from 0.5% to 1% in the latter...
This article describes an experimental program aimed at studying the influence of casting position on the cracking behavior of reinforced concrete elements. The effect of other parameters such as concrete cover, ratio between diameter and effective reinforcement ratio (ϕ/ρs,ef) and type of loading (tension or bending) is also studied. The experimental program was conceived in order to compare the...
