Please provide solved jpg answer $-$ step by step

A single$-$storey warehouse building in Goderich is $6m$ tall with the following layout:

The roof assembly is as follows:

$3-$ply asphalt and gravel roofing

$12mm$ gypsum wallboard

$150mm$ rigid fiberglass insulation

$12mm$ gypsum wallboard

$76mm$ deep narrow rib metal deck

$0\mathrm{.}20$kPa mechanical equipment suspended allowance

$0\mathrm{.}15$kPa OWSJ framing allowance

The snow load acting on the roof is provided by the equation $S=I_S(S_s(0\mathrm{.}8)+S_r),$ with $S_s$ and $S_r$

being dependent on the building's location $($refer to the NBCC $2020$ Appendix C$).$

The building is subject to windward pressure of $0\mathrm{.}55$kPa and a leeward suction of $0\mathrm{.}35$kPa.

Further, the building must withstand a total seismic force equal to $10\%$ of the total roof dead load
