reinforced concrete;  shear bearing capacity;  deep beams;  Short beams

On the basis of the systematic analysis of the shear performance of reinforced concrete beams, the shear performance test of 24 reinforced concrete beams subjected to concentrated load and uniform distribution load was carried out, and the main factors considered were shear span ratio (λ=a/h0), span height ratio (l0/h), horizontal and vertical rib reinforcement ratio (ρsh and ρsv). Finally, a unified calculation method for the shear bearing capacity of reinforced concrete beams in oblique section is proposed. This method can be used to calculate the oblique section bearing capacity of deep beam, short beam and shallow beam, and the calculation results are in good agreement with the test results.
