Design the cantilever rectangular reinforced beam shown in the figure. Provide a maximum of #8 size
bars, in two rows if necessary; f ’c = 3,000 lbf/in2, f y = 50,000 lbf/in2. Sketch the design. Include the self-
weight of the reinforced concrete beam. Apply Load Combination 2 only. Comply your design with the
ACI specifications for beams (see slides 28-32 of lecture ‘L07 - Concrete Flexion I’. Explain why the re-
inforcement steel has to be laid at the top and not at the bottom. Exploit the instructor spreadsheet calcula-
tor posted in D2L to speed up the numerical calculations.
