Truss Roof No Load Bearing Walls

Using this technique you ll get a better idea of the location of the load bearing walls in your house.

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. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses. In this case it is not an issue however. 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.

I have set many a girder atop a load bearing interior load bearing wall. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin. Load bearing walls cross roof beams in a perpendicular direction. I have also set many girders on point load posts in interior walls that someone might be in for a surprise if they think they could take out the wall.

A wall that is set directly over one of those beams is probably not a load. Trusses unless a special girder truss which accepts the loads of attached trusses have no interior load bearing walls. 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.

That is the beauty of trusses. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres.
