An experimental investigation was conducted to study the shear strength of full-scale beams constructed with both chemically-based self-consolidating concrete (SCC) and conventional concrete (CC). This experimental program consisted of 16 beams (12 without shear reinforcing and four with shear reinforcing in the form of stirrups). Additionally, three different longitudinal reinforcement ratios were evaluated within the test matrix. The beams were tested under a simply supported four-point loading condition. The experimental shear strengths of the beams were compared with the shear provisions of both U.S. and international design codes (U.S. [ACI-318 and AASHTO LRFD], Australia, Canada, Europe, and Japan) as well as a shear database of CC specimens. Furthermore, statistical data analyses (both parametric and non-parametric) were performed to evaluate whether or not there is any statistically significant difference between the shear strength of the SCC and the CC beams. Results of these statistical tests show there is no significant difference between the shear strength of the SCC and CC for the beams tested in this investigation.
