Question $2(12\mathrm{.}5$ points$)$

Question $2$:

Using Limit States Design criteria and OBC $2012,$ Part $4,$ for the floor and roof layouts below calculate

the total factored load at the base of column $1($Col $1)$ due to the following service loads:

Roof:

Dead load $DL=3\mathrm{.}28$KPa $($concrete$,$ roofing, insulation$)$

Live load due to occupancy $LL=1$KPa

Total Snow load S $=2\mathrm{.}44$KPa

Second floor:

Dead load DL $=2$KPa $($deck$,$ finishes$)$

Live load due to occupancy $LL=3\mathrm{.}6$KPa

Assume the following weights for the structural elements:

Joist $=0\mathrm{.}17K\frac{N}{m}$

Main Beam $=0\mathrm{.}24K\frac{N}{m}$

Column $=0\mathrm{.}48K\frac{N}{m}$; Height $of$ column $=5\mathrm{.}8\frac{m}{f}$loor

Column $=0\mathrm{.}48K\frac{N}{m}$; Height of column $=5\mathrm{.}8\frac{m}{?}$ floor

Load combination for a roof: $1\mathrm{.}25$DL$+1\mathrm{.}5$S$+1$LL

Load combination for a floor: $1\mathrm{.}25$DL$+1\mathrm{.}5$LL

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