shear reinforcment in concrete beams

[NS4U]

Attached a cross section of 5’ wide beam. My analysis indicates 2 legs of a stirrup are required for shear reinforcement.

My question: is there a problem with putting the reinforcement at one side of the beam as shown?

The beam you have sketched is only two foot wide for flexure since the portion outside of the stirrups can develop a horizontal/45 degree shear crack when the shear is greater than the concrete shear strength.

civilperson, but was is your Vc? entire width of the x-section? or just the width of the stirrup?
