Fink Roof Truss Load Bearing Wall

I have set many a girder atop a load bearing interior load bearing wall.

Fink roof truss load bearing wall.

There are such things as load bearing interior walls with trusses. Jim stewart jul 16 17 at 2 57 jimstewart true the clips would stabilize the bottom of the truss against lateral loads which is required but i think often the truss manufacturer will require x bracing on the bottom chord to keep it vertical. Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.

Calculate the tension and compression forces on each member given the load requirements below. Each truss is responsible for a 2 foot section through the roof as trusses are typically placed 24 apart and thus must carry 12 on either side. 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. 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.

We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin. Also he said because there is no beam below the wall or anything else to carry the load to the slab in the basement that automatically disqualifies the wall from being load bearing because a home would never be designed to carry roof load on your floor joists. 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. So removing the non load bearing partition wall might reduce the stability of the trusses.

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. 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. He said the chances the wall is load bearing are very small to none because the bottom plate of a fink truss is designed to be in tension not compression. In this case it is not an issue however.
