Truss Roof No Load Bearing Walls

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.

Truss roof no 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. That is the beauty of trusses. In this case it is not an issue however. Using this technique you ll get a better idea of the location of the load bearing walls in your house.

Trusses unless a special girder truss which accepts the loads of attached trusses have no interior load bearing walls. With your trusses spanning the exterior walls for the full run of the house no interior walls will be load bearing the splices on trusses are engineered to be self supportive according to the plate sizing the fact that they land over an interior wall has nothing to do with that wall being load bearing trusses are engineered to span exterior wall to exterior wall self supporting. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres. Technically the interior partition walls shouldn t even be touching the truss bottom cord during rough in but they usually are.

Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses. If a wall is located on the ground floor go down to the basement to observe the ceiling beams. A wall that is set directly over one of those beams is probably not a load. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin.

I have set many a girder atop a load bearing interior load bearing wall. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. There are such things as load bearing interior walls with trusses. By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself.
