5.12. Design the shear reinforcement, using No. 4 (No. 13) vertical U stirrups lothe independent T beam shown in Fig. P5.12. The beam spans 24 ft face toface between simple

supports, has an effective depth d = 31 in., and is reinforced for flexure with six No. 10 (No. 32; bars in two layers that continue uninterrupted to the ends of the span. It is to carry service dead load= 267 kips/ft including self-weight) and service live loud L=5.36 kips/n. both uniformly distributed along the span. Equation (5.120 may be used. Material strengths are f= 5000 psi and fy = 60,000 psi
