According to ACI-308-08,the RC beam can separate into slender beam and deep beam. If a/h < 2, it is classified as deep beams. Recently, we use Strut and Tie Model to calculate the shear strength. But in this theory, it is difficult to apply to non-rectangular beam. Among the normal structures, T-beam, which is formed from flange and rectangular beam, belongs to the type of non-rectangular beam. The research focuses on the effect of flange on shear strength.
The specimen of this experiment designs different flange areas, included rectangular beam, T beam…. all 8 specimens. The result of this experiment confirms that different flange areas really affect shear strength and that strut and tie model, which is issued by CSA Code, inaccurately assess diagonal strut strength. Finally, The effect flange width is mainly adopted in to the evaluation of shear strength of T-section short beam by means of strut and tie model methodology
