Truss Roof No Load Bearing Walls

So you could have a minor gap with no load at the end of construction but during snow load you could have a truss failure.

Truss roof no load bearing walls.

That is the beauty of trusses. To prevent these problems the gap between the truss and the non bearing wall should be enough so that it does not close when the load is applied to the truss. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres. 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.

Technically the interior partition walls shouldn t even be touching the truss bottom cord during rough in but they usually are. The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.
