Shear reinforcement in a concrete beam is required when the shear strength of concrete alone is inadequate to carry the vertical shear from external loads. ACI 318 stipulates the general equation for computing the vertical shear strength of a concrete beam with inclined stirrups as follows. Vs = As*fy*d/s*(sin(a) + cos(a)) where a = horizontal angle of the inclined stirrup It's first astonishing to see the term cos(a) for the shear strength of the stirrup, which should only b
