A simply supported rectangular RC beam is to carry a uniform factored dead load of 1.2 kip/ftand a concentrated factored live load of 16 kip at mid-span. The beam self-weight is not includedin these loads. The concrete weighs 135 pcf. The span length is 25 ft. Please find the smallestsection allowed by ACI and design accordingly. Use f c’ = 5,000 psi, f y = 75,000 psi. Theexposure is interior with no weather exposure.a. Assume an arbitrary self-weight/ft of the beam.b. Find the maximum factored bending moment in the beam.c. Set up the moment equation and solve for the beam section.d. Revise the assumption if needed.Hint: The beam section (b and h) and steel reinforcement are inversely proportional. The smallestallowable beam section will be for the largest allowable steel ration (ρmax), and vice versa. Sincethe steel ratio is fixed, two remaining variables (b, d) need to be found from the moment equations.Then, bd2 term can be solved to get an acceptable b and d combination.

- Design a cantilevered rectangular RC beam subjected to a maximum factored load bending moment, M u = 260 kip-ft. The clear height requirements for the building limits the total beam depth to 22 in. Determine the beam width and the steel design. Use f c’ = 6,000 psi, f y = 40,000 psi. The grade beam is cast against earth and permanently in contact with soil. a. Assume an initial steel ratio or beam width. b. Set up the bending design equation. c. Solve for either the steel ratio or the beam width. d. Design needed steel. 2 Hint: Knowing “h”, one can estimate the “d” value. So, two remaining variables can be estimated. There are many acceptable solutions. You can either assume a steel ration and solve for width “b”, or assume a beam width “b” and solve for the steel ratio.
