They are the walls that carry the weight of the home.
Engineered roof trusses load bearing walls.
These are structurally engineered not only to bear the weight and stress of a home but also to resist earthquakes heavy winds and other weather related events.
If there is a column that supports the truss found in the wall the wall still would not be load bearing because the column is taking the load.
This is the distance of the bottom chord of the truss from outside overhang of bearing wall to outside of the other bearing wall.
The span in short is the length of the bottom of the truss.
Usually load bearing interior walls support the structure above directly by the components of the wall.
Technically the interior partition walls shouldn t even be touching the truss bottom cord during rough in but they usually are.
Factors that affect truss pricing and cost.
If all the trusses are identical they can t be load bearing with walls in three different spots.
I would think that any wall with a truss over it is not likely to be load bearing.
We built our own home and it is about 33 wide.
Trusses unless a special girder truss which accepts the loads of attached trusses have no interior load bearing walls.
Load bearing interior wall under truss roof.
The roof trusses span the whole distance.
Stick built roofs tend to only span about the same distance as floor joists and would require load bearing interior walls to support them.
That is the beauty of trusses.
Some spans have a lower rate per foot than others.
Johnson got it right.
Engineered trusses tend to be designed to span from exterior wall to exterior wall.
Load bearing walls are fairly self explanatory.
By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself.
Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load.
