Q$3-$ P$5-15$

Assume the maximum factored negative moment at the

support of the floor beam $m-n-o-p$ is $-195k-ft.$ Using the

design procedure for singly reinforced beam sections given in

Section $5-3($design of beams when section dimensions are

not known$),$ determine the beam dimensions and select the

required area of tension reinforcement to satisfy all the ACI

Code requirements for strength and minimum reinforcement

area. Select bars and provide a sketch of your final section

design. Use $f_c^{\text{'}}=5000$ psi, $f_y=80$ kis.
