Consider the beam and factored loads shown below.

a$.$ Select a reasonable size and spacing of stirrups. Use the simplified concrete shear strength

formula from Table $22\mathrm{.}5\mathrm{.}5\mathrm{.}1($a$)($the simpler of the two $V_c$ equations provided in class$).$

Select a critical section located $d$ from the face of supports wherever permitted by ACI

$9\mathrm{.}4\mathrm{.}3\mathrm{.}2($assume the face of the support is $6$ in$.$ from the center of the support$).$ Although

most beams are symmetric, this case is not... so please use different stirrup spacings at each

end and at midspan if appropriate. Discontinue stirrups where they are no longer needed.

Stirrup spacing should be given in integer values, and be preferably no less than $4$ in$.$

b$.$ Draw cross$-$section and elevation views of the beam illustrating stirrup detailing and

placement.
