Analysis of shear bearing capacity of HRB500-reinforced concrete beams

Ren Ze-min

Abstract

The shear bearing capacity of concrete beam with HRB 500 bar and the impact of the T-section′s flange at service stage on the width of crack and on the shear bearing capacity were analyzed according to the tests of 8 concrete beams with HRB500 steel bar under concentrated load.The comparison of shear bearirg capacity between T-section beam and rectangular one was carried out.There is certain influence of T-section′ flange on width of the diagonal crack,but it is not considerable and the shear bearing capacity of the T-section beam is larger than that of rectangular section one.
