2 A rectangular reinforced concrete beam is to be designed to withstand a moment, Mu = 350 ft.-k, the maximum moment on a simple span beam. This moment includes the self-weight of the beam. The beam width, b, is 15 in. and the total height, h, is 24 in. Assume d = 20 in. and d' = 2.5 in. Design the flexural reinforcement, using #8 bars for bottom reinforcement and #8 bars for top reinforcement, if necessary. Regardless of whether the beam is a doubly reinforced beam or not, assume the tensile reinforcement is placed in two equal rows of #8 bars (i.e. an equal amount of reinforcement in each row) spaced with a 1.0-in. clear distance between rows. Assume fc' = 3,000 psi and fy = 60,000 psi
