Use OBC $2012$ and current CSA$-$O$86$ for the roof plan below.

Wood Beam $1$ is considered simply supported at ends.

Specified dead load: DL$=0\mathrm{.}82$KPa $($roofing and deck$)$

Location: Hastings, Ontario

Assume joist weight: $0\mathrm{.}12K\frac{N}{m}$

Assume beam weight: $0\mathrm{.}38K\frac{N}{m}$

For Beam $1$ determine what is the specified load required for DEFLECTION, $w_5?$ What is the minimum required $($EI$)$ req for calculation of BEAM $1$ deflection?

Select one correct answer from the options below.

$w_5=7K\frac{N}{m},(El{)}_{\text{r}\text{e}\text{q}}=4613\mathrm{.}7{10}^{9}Nm{m}^2$

$w_5=7K\frac{N}{m},(El{)}_{\text{r}\text{e}\text{q}}=5249\mathrm{.}44{10}^{9}N{m}^2$

$w_5=8\mathrm{.}15K\frac{N}{m},(EI{)}_{\text{r}\text{e}\text{q}}=3586\mathrm{.}27{10}^{9}Nm{m}^2$

$w_5=8\mathrm{.}15K\frac{N}{m},(EI{)}_{\text{r}\text{e}\text{q}}=4386\mathrm{.}02{10}^{9}Nm{m}^2$

$w_5=6\mathrm{.}03K\frac{N}{m},(EI{)}_{\text{r}\text{e}\text{q}}=4522\mathrm{.}6{10}^{9}Nm{m}^2$
