Using Limit States Design criteria per OBC $2012,$ Part $4,$ and load transfer method, for the roof layout below calculate the total factored load at the base of column $1($Col $1)$ due to the following loads:

Roof service loads:

Dead load DL $=2$KPa $($deck$,$ roofing, insulation$)$

Live load due to occupancy LL $=1$KPa

Total Snow load S $=3\mathrm{.}4$KPa

Assume the following weights for the structural elements:

Joist $=0\mathrm{.}1$KN$/$m

Secondary beam $=0\mathrm{.}2$KN$/$m

Main Beams $=0\mathrm{.}6$KN$/$m

Column $=0\mathrm{.}5$KN$/$m; Height of column $=5$m

All joists, beams and top of column are flush at the top.
