Question: 1 / 400

Diagonal top chord braces are critical to prevent the top chords from buckling under forces such as wind. How else can this be done so the braces do not have to be removed when sheathing the roof?

Run the diagonal top chord braces on the underside of the top chords.

Diagonal web bracing at each gable end running in both directions (an ΓÇ£XΓÇ¥).

Run diagonal web braces at each gable end from top of gable and angled back to the fourth or fifth bottom chord.

Run all the truss top chord lateral braces on the underside of the top chord.

The option to run all the truss top chord lateral braces on the underside of the top chord addresses the structural integrity of the truss system while allowing for sheathing installation without the need for brace removal. By placing the braces on the underside, they remain hidden from the roof's surface, facilitating easy access and installation of sheathing materials. This arrangement also maintains effective support against lateral loads, helping to prevent buckling of the top chords under forces like wind without compromising the construction workflow.

Additionally, this method ensures that the trusses maintain their strength and stability, thereby contributing to the overall safety and durability of the roof structure. It allows for a more streamlined construction process since all necessary structural elements remain intact during and after the sheathing process, enhancing efficiency on the job site.
