Engineered Roof Trusses Load Bearing Walls

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.

Engineered roof trusses load bearing walls. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. If all the trusses are identical they can t be load bearing with walls in three different spots. That is the beauty of trusses. Factors that affect truss pricing and cost.

Load bearing interior wall under truss roof. By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself. They are the walls that carry the weight of the home. 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.

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. The span in short is the length of the bottom of the truss. Some spans have a lower rate per foot than others. This is the distance of the bottom chord of the truss from outside overhang of bearing wall to outside of the other bearing wall.

I would think that any wall with a truss over it is not likely to be load bearing. Johnson got it right. Stick built roofs tend to only span about the same distance as floor joists and would require load bearing interior walls to support them. Technically the interior partition walls shouldn t even be touching the truss bottom cord during rough in but they usually are.

The roof trusses span the whole distance. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. Engineered trusses tend to be designed to span from exterior wall to exterior wall. Load bearing walls are fairly self explanatory.

Usually load bearing interior walls support the structure above directly by the components of the wall.
