Truss Roof Load Bearing Wall

If truss was build as a one piece truss it shouldn t be center bearing.

Truss roof load bearing wall.

Joists are rarely continuous over the top of a wall instead they are often spliced over the top of the wall as dimensional lumber only available in specific lengths. 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. 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. Having said that i d still just put a dbl 2x10 w ply flitch header in call it a day.

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. When joists trusses are perpendicular to the wall and bear o n the top of the wall that wall is bearing wall. An example of a load bearing wall call be seen on the right. The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle.
