$1.$Shown below is a larger$-$scale elevation view of the left end of the

continuous concrete beam shown in Figure $13\mathrm{.}29$ of the text. The

structural plans call for a ${10}^{?}-$wide by ${18}^{\text{'}\text{'}}-$deep $(254$ by $460$ mm $)$

beam with two #$9$ top bars and two #$8$ bottom bars. Fifteen #$3$ U$-$

stirrups are required at a spacing of $7^{\text{'}\text{'}}(178mm).$

Make an accurately scaled

drawing of the reinforcing bars

in the beam, including top bars,

bottom bars, and stirrups,

drawing them as if the concrete

were transparent. Give critical

dimensions of any hooks. Do not

show column reinforcing or bar

deformations.

$2.$On the cross section to the left, draw

accurately to scale the top bars.

bottom bars, and U$-$stirrups for this

beam. No dimensions are required. The

hooks on the stirrups should face the

center of the beam section.

$3.$The simply supported beam whose end

is shown in elevation below has three

#$7$ bottom bars with hooked ends and

#$3$ stirrups at the same spacings as

those in part $1$ of this exercise. Draw

the reinforcing in the beam and give

critical dimensions of any hooks. Do not

show column reinforcing.
