A Simply supported rectangular, tension-reinforced beam is to be designed for dead load of 0.75 k/ft plus self weight and service live load of 2.0 k/ft, with a 30 -ft simple span. Material strength will be fy = 60 ksi and fc = 5 ksi for steel and normal weight oncrete respectively.
Startthe design of the beam dimensions using the rules of thumbs in class. The total beam depth, h, must not exceed twice the width.
Calculate the required beam dimensions and tensile steel requirement (As required) to carry the Maximum moment found at mid span. Start with a steel ratio of half of "usable rho" in Table 27.2 in the text. Use ACI load factors and strength reduction factors. The effective depth (d) may be assumed at 3 inches less than the total depth (h).
Draw a sketch clearly showing spacing, cover, and bar locations.
