The framing plan below is the typical framing plan that was used to build a $4-$storey building. In the east$-$west direction, there are four bays spaced at A $=10\mathrm{.}4$ m$,$ and in the north$-$south direction there are three bays spaced at B $=9\mathrm{.}2$ m$.$ If the occupancy use for the interior floors of the building at each level is office space, calculate the live load reduction factor for the live axial load from the occupancy loads on most heavily loaded section of column $4$B$.($Note: $2$ Joist per Bay$)$

Give you answer to two decimal places.
