Fink Roof Truss Load Bearing Wall

Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.

Fink roof truss load bearing wall.

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. The house has partition walls all over and the trusses are spaced 16 o c. Calculate the tension and compression forces on each member given the load requirements below. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.

Roof live load 25 lb ft2 b. Roof dead load 15 lb ft2 c. So even with a couple failed trusses the roof hasn t gone anywhere. Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls.

There is a center wall that i want to remove between the kitchen and living room and have been told that it is not a problem because of the trusses. There are three local architect firms by local i mean within a 2 hour drive that have a structural engineer on staff. 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. There are such things as load bearing interior walls with trusses.

Okay so problem 1 is the wall load bearing. I can see from the framing that it is not a load bearing wall no headers over the doorway. Ceiling dead load 10. 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.

I have set many a girder atop a load bearing interior load bearing wall. So removing the non load bearing partition wall might reduce the stability of the trusses. In this case it is not an issue however. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin.
