$1.$ Review Figures $5\mathrm{.}17$ through $5\mathrm{.}20$ and pages $163$ through $165$ in your text. Referring to the preliminary design guideines on page $189,$ jot down the maximum spans for $\backslash (2\backslash$times $8,2\backslash$times $10\backslash )$ and $\backslash (2\backslash$times $12\backslash )$ wood joists. $($See the note below if you wish to complete this exercise with I$-$joists.$)$

$2.$ Examine the floor plan, searching for a simple arrangement of joists and beams, working within the span limits noted above. To avoid complications for the carpenters, use one size of joist throughout.

$4.$ Draw in the beams and locate poste assuming beams can span $15$ to $\backslash (20^\{\backslash$prime$\}(4\mathrm{.}6\backslash$mathrm$\{$~m$\}\backslash )$ to $6\mathrm{.}1$ m$\backslash ()\backslash )$ between supports. Add doubled headers and trimmers around stair's, chimneys, and other floor openings. Add doubled joists wherever partitions run parallel to the framing below.

$5.$ Next lay out the framing for any cantilevered baye. The length of a cantilever should be no more than one$-$third the length of the interior span, and not more than one$-$fifth of the allowable span for the joist.

$6.$ Complete the framing plan by adding the remainder of the joists at a spacing of $\backslash (16^\{\backslash$prime $\backslash$prime$\}(400\backslash$mathrm$\{$~mm$\})\backslash )$ o$.$c$.$ Start at one edge and work across the platform, faithfully maintaining this spacing regardless of the placement of other framing members.

$7.$ Add joist hangers wherever joists are supported by headers. Add solia blocking wherever joists span across a beam or cantilever over a wall. Consider adding bridging at the midpoint of longer spans or deeper joists.

You may also complete this assignment using $|-$joists as follows: Limit the maximum $1-$joist depth to $12"(300$ mm$)$; space Fjoists at $\backslash (24^\{\backslash$prime $\backslash$prime$\}\backslash )(600$ mm $)$ o$.$C: substitute structural composite beame, such as LVLS$,$ for doubled. joists and headers; and limit cantilevers to one$-$fourth of the interior span.
