$(15$ percent$)$ Consider the masonry column shown in the photograph. This column supports a roof snow load in Colorado. The column measures $23\mathrm{.}625$ inches by $23\mathrm{.}625$ inches $($nominally $24$ inches square$).$ The column is $42$ feet tall and the load is applied concentrically between pinned supports.

$(15$ percent$)$ For the column considered in Question $4,$ consider if the column were to be reinforced with four total No$.4$ rebars spaced vertically each placed $2"$ in set from the corner. F$\text{'}$m $=2,000.$

$5$a$)$ What would be the reinforcement ratio, $?$

$5$b$)$ What would be the nominal column capacity, Pu$?$

$5$c$)$ What vertical ties are required? $($size and spacing draw a section$/$plan$)$
