A rectangular, tension-reinforced beam is to be designed for dead load of 500 lb/ft plus self-weight and service live load of 1200 lb/ft, with a 22 ft simple span. Material strengths will be f, = 60 ksi and f 3 ksi for steel and concrete, respectively. The total beam depth must not exceed 16 in. Calculate the required beam width and tensile steel requirement, using a reinforcement ratio of 0.60po.005: Use ACI load factors and strength reduction factors. The effective depth may be assumed to be 2.5 in. less than the total depth.
