Abstract:A total of six pretensioned prestressed single T-beams with identical flexural reinforcements and shear span-to-depth ratio were tested statically up to failure to investigate the effectiveness of welded wire fabric as shear reinforcement. The tested beams featured one beam without shear reinforcement and five beams with different types of shear reinforcement, including conventional double-legged stirrups, single-legged stirrups, and three different types of commercially available welded wire fabric (WWF). The results indicated that the effectiveness of WWF as shear reinforcement is the same as that of conventional stirrups under static loading conditions. It was found that using deformed WWF slightly improved the distribution of the diagonal cracks. Anchorages of WWF by means of two horizontal wires at the top and bottom are adequate according to ACI Building Code recommendations.
