A 12 in. x 18 in. rectangular beam has an effective span of 20 ft. A dead load of 1500 lb/ft (includes self weight) and a live load of 4000 lb/ft is applied to the beam. The concrete and steel strengths are 4000 psi and 60000 psi respectively. Design and detail the shear reinforcement for the beam. Assume d is 2 inches less than h
