Trussed Roof With None Load Bearing Walls

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.

Trussed roof with none load bearing walls. When joists trusses are perpendicular to the wall and bear o n the top of the wall that wall is bearing wall. To enable the roof truss to deflect under loads nails to the truss must be installed at the top of the slotted holes and not hammered home to allow a loose fit only. An example of a non load bearing partition wall can be seen on the left. They do this by means of top chords which are sloping members that extend from the peak of the roof to the top of the exterior walls at the eaves.

Just a quick consideration of your situation if the interior wall was framed after the trusses roof sheathing roofing were installed then i would expect little deflection after removing the interior wall. One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing. Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls. If the wall in question is parallel to the joists trusses it will likely not be load bearing.

Actually a quick way to determine if the wall is bearing is to cut hole at the top to see if it has one or two top plates. Regardless the wall beneath it is likely not load bearing. However if the interior wall was framed before the trusses were set it is possible that the wall prevented deflection of the trusses from the dead load of the trusses sheathing. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.

An example of a load bearing wall call be seen on the right. Best answer so far. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres.
