Roof dead load 15 lb ft2 c.
Fink roof truss load bearing wall.
The house has partition walls all over and the trusses are spaced 16 o c.
I can see from the framing that it is not a load bearing wall no headers over the doorway.
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.
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.
Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses.
Ceiling dead load 10.
I have set many a girder atop a load bearing interior load bearing wall.
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.
Due to the age of the house should i be concerned that the roof may sag after removing the wall.
In this case it is not an issue however.
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.
Roof live load 25 lb ft2 b.
There are three local architect firms by local i mean within a 2 hour drive that have a structural engineer on staff.
Okay so problem 1 is the wall load bearing.
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.
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.
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.
Calculate the tension and compression forces on each member given the load requirements below.
