Problem 3

A reinforced concrete beam is cantilevered over a span of 10 ft. The beam width is 14”. The beam is supposed to carry a uniformly distributed service dead load of 1.2 k/ft and a uniformly distributed service live load of 0.5 k/ft over its entire span. The dead load includes an allowance for the beam weight. Assume 60- ksi steel and 4,000-psi concrete.

1.Use the design equations to determine the minimum required effective depth (d).

2.Select the tensile reinforcement, and draw a typical section in the beam showing all relevant dimensions and required rebars.
