Engineered Roof Trusses Load Bearing Walls

Some spans have a lower rate per foot than others.

Engineered roof trusses load bearing walls.

Johnson got it right. 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. Stick built roofs tend to only span about the same distance as floor joists and would require load bearing interior walls to support them.

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. I would think that any wall with a truss over it is not likely to be load bearing. If all the trusses are identical they can t be load bearing with walls in three different spots. 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.

This is the distance of the bottom chord of the truss from outside overhang of bearing wall to outside of the other bearing wall. Factors that affect truss pricing and cost. Load bearing walls are fairly self explanatory. Engineered trusses tend to be designed to span from exterior wall to exterior wall.

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. They are the walls that carry the weight of the home. Trusses unless a special girder truss which accepts the loads of attached trusses have no interior load bearing walls. Usually load bearing interior walls support the structure above directly by the components of the wall.

The first and second floors have 13 5 9 and 9 5 spans add the 6 per bearing wall and each exterior wall you get 33. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. That is the beauty of trusses. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.

We built our own home and it is about 33 wide.
