Study on Shear Strength of Reinforced Concrete T Beams based on the Size Effect

Abstract

Size effect has great influence on the shear strength of reinforced concrete T beams, flange width changes the shear mechanism of reinforced concrete T beams. In combination with shear database, comparing the calculation results of formula based on the effective flange width with other specifications formulas by means of Matlab, the flange width can increase the shear capacity of reinforced concrete T beams, and the recommended formula considering the effective flange width is reasonable.
