Question
Design a double-reinforced concrete beam to resist the moment due to a service dead load D = 150,000
lbf*ft (including self-weight) and the moment due to a service live load L = 160,000 lbf*ft. Apply Load
Combination 2 only. The beam width is limited to 11 in, and the effective depth d is limited to 20 in. The
compression steel cover is 3 in from the top (measured to centerline of compressive rebars). Use f ‘c =
3,000 lbf/in2, fy = 60,000 lbf/in2.
