Fink roof truss load bearing wall.
So even with a couple failed trusses the roof hasn t gone anywhere.
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.
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.

Ceiling dead load 10.
In this case it is not an issue however.

Calculate the tension and compression forces on each member given the load requirements below.
Due to the age of the house should i be concerned that the roof may sag after removing the wall.
There are three local architect firms by local i mean within a 2 hour drive that have a structural engineer on staff.
Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.

The house has partition walls all over and the trusses are spaced 16 o c.
So removing the non load bearing partition wall might reduce the stability of the trusses.
Okay so problem 1 is the wall load bearing.
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.
Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls.
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.
