Truss Roof No Load Bearing Walls

In this case it is not an issue however.

Truss roof no load bearing walls.

If a wall is located on the ground floor go down to the basement to observe the ceiling beams. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres. Load bearing walls cross roof beams in a perpendicular direction. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin.

Trusses unless a special girder truss which accepts the loads of attached trusses have no interior 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. 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. Using this technique you ll get a better idea of the location of the load bearing walls in your house.

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. Technically the interior partition walls shouldn t even be touching the truss bottom cord during rough in but they usually are. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. 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.

That is the beauty of trusses. By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself. There are such things as load bearing interior walls with trusses. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.
