ABSTRACT
Tests on beams show many different types of shear failure. Some common types of failure are discussed below.
Shear compression: Cracks which start as vertical cracks due to flexural stress, because of the effect of shear stresses, become inclined as they penetrate deeper into the beam. If the compression area above the inclined crack is inadequate to resist the compression resulting from bending moment, concrete in the
