Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.
Non load bearing roof truss.
Chances are this is a non bearing.
Members which are expensive and might require either additional beams or interior load bearing walls trusses can span a longer distance without additional supports while using less expensive members.
For example a gable end truss may be designed with support members that transmit the roof weight load outward to the side walls allowing the end wall directly below it to have breaks or openings in it that would otherwise be impossible.
On a recent project with precision end trimmed studs the contractor suggested using a single top plate at the non load bearing walls so all the studs could be the same length and not have an issue at non load bearing walls.
If you are able to see the floor framing or roof framing you fir st want to locate the floor joists or roof trusses.
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.
Best answer so far.
Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.
Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls.
An example of a non load bearing partition wall can be seen on the left.
While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses.
I always use details to show separation and clips between non load bearing walls and trusses.
One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing.
Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.
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.
We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin.
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.
Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres.
