Question $1(10$ marks$)$

Consider the following typical framing plan and cross$-$section:

The loads on the roof are: Dead Load: $1\mathrm{.}6$kPa. Snow Load: $2\mathrm{.}0$kPa

The loads on each occupied floor are: Dead Load: $1\mathrm{.}4$kPa, Live Load: $2\mathrm{.}4$kPa $($office occupancy$)$

Framing self$-$weight may be neglected throughout.

Determine the minimum acceptable size of the noted column at the ground floor level

assuming it is S$-$P $12$c$-$E Glulam and protected from fire. Provide a secondary size for the

column if it is to be exposed to fire for $60$ minutes.

In the case of errors, part marks will be given for intermediate determinations, such as:

Factored area load acting on the roof and floor, factored line load per beam

Factored force at the subject column, including any necessary increases or reductions

Consideration of modification factors, if applicable.
