They Supported The Weight Of The Roof And The Walls

They should be designed to span the whole width but they also could have been engineered to have a load bearing wall.

They supported the weight of the roof and the walls.

Not all external walls are always load bearing. Go up in the attic and find where the wall you want to remove hits the ceiling. See if you have a hole in it where you can see if it is a double top plate. Framing materials are usually wood engineered wood or structural steel the alternative to framed construction is generally called mass wall construction where horizontal layers of stacked materials such as log building masonry rammed earth adobe etc.

Trusses are pre fabricated triangulated wooden structures used to support the roof. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. Framing in construction is the fitting together of pieces to give a structure support and shape. Trusses are quite common these days because they have five big advantages from the builder s standpoint.

When in doubt about whether a wall is supporting treat it as if it is. This house uses trusses for the roof framing. The spacing and allowable span of ceiling joists in residential construction is standardized according to building codes which cover not only basic wall to wall room design but nonparallel. 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.

If so it is probably load bearing. The alternative is to build up the roof s frame with 2x8s and 2x10s. Are used without framing.
