An experiment was conducted to study the effect of reinforced flanges on the torsional capacity of reinforced concrete T-beams (Journal of the American Concrete Institute, Jan.–Feb. 1986). Several different types of T-beams were used in the experiment, each type having a different flange width. The beams were tested under combined torsion and bending until failure (i.e., cracking). One variable of interest is the cracking torsion moment at the top of the flange of the T-beam. Cracking torsion moments for eight beams with 70-cm slab widths and eight beams with 100-cm slab widths are recorded here. Is there evidence of a difference in the locations of the cracking torsion moment distributions for the two types of T-beams? Test using α = .10.
