Abstract：Based on the shear bearing capacity calculation formula of reinforced concrete rectangular beams, with considering the compression width of reinforced concrete T beams and defining an effective flange width, the formula of shear bearing capacity of reinforced concrete T beam was deduced with considering the effective flange width. The shear test data of 1 reinforced concrete rectangular beam and 61 reinforced concrete T beams were collected. The calculation results of shear bearing capacity were compared with different domestic and overseas specifications and deduced formula. The standard formula for calculating shear bearing capacity of T beams is safe, while the calculated results by deduced formula are in good agreement with test data. The flange width of reinforced concrete T beams can obviously improve shear bearing capacity, and the deduced formula is more suitable.
