EXPERIMENTAL STUDY ON SHEAR STRENGTH OF REINFORCED CONCRETE BEAMS WITH T-SHAPE OR HOLLOW SECTION

Abstract

 It is known that the shear strength of a member with a T-shape or hollow rectangular cross section is greater than the value calculated by the shear strength calculation method in accordance with the current standard. This study examined a method for calculating the shear capacity value closer to the actual value by conducting a shear test of a RC beam having such a cross section. Since the test result showed that a diagonal crack occurred in the web of a member before its flange was failed, a calculation method was verified by adding the shear strength of the flange to that of the rectangular part of the cross section. As a result, it was confirmed that this method calculates the value closer to the actual shear strength compared with the currently used shear strength calculation method.
