A rectangular concrete beam of width b = 24 in. is limited by architectural considerations to a maximum total depth h = 16 in. It must carry a total factored load moment M u = 400 ft-kips. Design the flexural reinforcement for this member, using compression steel if necessary. Allow 3 in. to the center of the bars from the compression or tension face of the beam. Material strengths are f y = 60,000 psi and f c ′ = 4000 psi. Select reinforcement to provide the needed areas, and show a sketch of your final design, including provision for No. 4 (No. 13) stirrups.
