Abstract
Present study describes an investigation into the causes of shear failure of reinforced concrete beams subjected to two point loading with shear span/depth ratio greater than 2.5. In this investigation tests are carried out on four reinforced concrete beams labelled as B1, B2, B3 and B4 are identical in geometry, flexural reinforcement, material properties and test details. The only variable is shear stirrups spacing along the member length. Strength and performance of beams with various arrangements of stirrups are verified. An experimental study of beams with various arrangements of shear stirrups has indicated that the predicted behaviour is incompatible with the concept of shear capacity at critical sections that forms the basis of current shear design procedures. The results obtained support the view that shear failure is associated with the development of tensile stresses within the compressive zones of the beams.
