Tutorial Task$-4$: Combined Actions

Question:

Figure $1$ gives a $3$D view of a store, to be built with timber in Hobart, Tasmania. The building will be

subjected to different load combinations. Corner column $AB$ will carry $20kN$ compressive force

$($factored$)$ due to permanent actions $(1\mathrm{.}35$G$)$ and $2\mathrm{.}5kNm$ bending moment $($factored$)$ due to

combined imposed action considered as "five months duration" and permanent actions $(1\mathrm{.}2G+1\mathrm{.}5Q.$

Consider the bending moment will act about the major axis. The intermediate lateral restraints are

shown in Figure $1.$ The column will be from MGP $12-19045mm$ made from seasoned Ash

Mountain species. Each end of the columns will be held by bolts. Check if column $AB$ can carry the

combined actions.
