A singly reinforced rectangular beam is to be designed, with effective depth approximately 1.5 times the width, to carry a service live load of 2000 lb/ft in addition to its own weight, on a 24 ft simple span. The ACI Code load factors are to be applied as usual. With f, 60,000 psi and f = 4000 psi, determine the required concrete dimensions b, d, and h, and steel reinforcing bars (a) for p= 0.60pmax and (b) for p = Po.005. Include a sketch of each cross section drawn to scale. Allow for No. 4 (No. 13) stirrups. Comment on your results.
