Abstract:
Twenty-five small semicontinuous reinforced concrete L-beams without stirrups were tested under combined torsion, shear, and flexure. The test program was designed to study the effect of percentage of longitudinal steel, flange width and eccentricity of loading on both behavior and strength. Ultimate strength was greatly influenced by the eccentricity. Even small torques decreased the capacity of test specimens; beams with smaller flanges suffered more reduction in capacity. The percentage of longitudinal steel influenced the ultimate load capacity of specimens tested under small eccentricities. At high eccentricities the effect of longitudinal steel was not significant.
