CLT and GLT wood are considered heavy timber. Heavy timber performs better than $2$x$4,2$x$6$ construction since $,$ when the CLT or GLT floor$/$wall catches fire, the outside surface chars, and thus begins to protect the wood inside the char area. The fire resistance rating $($example $1/2$ hr$,1$ hr$,2$ hr$,$ or $3$ hour etc$)$ is calculated $,$ for CLT and GLT$,$ based on the "effective char depth" $.$ You should review this in Chpt $8$ of the CLT handbook. Question: Per the Table in Chpt $8$ of the CLT handbook, if your effective char rate is $1\mathrm{.}67$ inches per hour of the CLT you are considering in your project, then what is your allowable fire resistance? Pick best answer based on the table. Note that the longest allowable time is the correct answer $($since the longer it can withstand a fire, the better$)$ Group of answer choices $1/2$ hour $45$ minutes $1$ hour $11/2$ hour $2$ hour the wood can withstand a fire for more than $2$ hours
