$7\mathrm{.}2$ Compute and draw to scale the envelope of bending moments $($diagram showing range over which bending moment may vary$)$ due to factored loads for the beams of the frame of the figure for Problems $7\mathrm{.}2$ and $7\mathrm{.}3$ using any structural analysis method assigned by the instructor. The uniform factored dead load is $1ki\frac{p}{f}t,$ and the uniform factored live load is $2$kip$\frac{s}{f}t.$

$7\mathrm{.}3$ For the beams of the frame in the figure, compute and draw the bending moment envelope using the coefficients of ACI$-6\mathrm{.}5\mathrm{.}2.($If Problem $7\mathrm{.}2$ has also been solved, compare the moments by giving the percentage difference in the maximum values obtained by coefficients as compared with the more exact values of a structural analysis.$)$
