$4\mathrm{.}2$ Cross$-$Laminated Timber Panels

Sketch a CLT panel section for each of the following. Draw to the scale indicated, label all parts, and provide a dimension for the total thickness of the panel and any applied fireproofing. For help sizing CLT panels, see the Chapter $4$ sidebar, "Preliminary Design of Heavy Timber and Mass Timber Structures." In all cases, assume a lamination thickness of $\frac{13}{8}$ inches $(34mm).$

a$.$ A lightly loaded interior

wall panel, with no fire

resistance rating required:

b$.$ An interior wall panel supporting medium

loads, with a $1-$hour

fire resistance rating

provided entirely by

encapsulation:

c$.$ A floor panel

supporting medium

loads, spanning $16$

feet $(4\mathrm{.}9m),$ with no

fire resistance rating

required:

Scale: $3^{\text{'}\text{'}}=1^{\text{'}}(1$:$4)$

$1$ square $=1^{\text{'}\text{'}}(25mm)$
