A rectangular column section $16$ in$.x20$ in$.$ is subjected to $P_u=440$ kips, $x=225k-$ft$,$ and $y_y=150k-$ft$.$ This column was reinforced with $10-$ #$8$ bars. Concrete cover to centroid of adjacent bar is $2\mathrm{.}5in.$ All bars are equally spaced along each column face. Use $f_c^{\text{'}}=6000$ and $f_y=60$ksi. Evaluate the adequacy of the column section using

i$.$ Bresler reciprocal load method

ii$.$ Bresler load contour method

iii. PCA load contour method
