Non Load Bearing Roof Truss

The remaining third node of each triangle is known as the load bearing node.

Non load bearing roof truss.

Chances are this is a non bearing wall. This type of truss is perfect for the dining room living room great room and kitchen. When joists trusses are perpendicular to the wall and bear on the top of the wall that wall is bearing wall. An example of a non load bearing partition wall can be seen on the left.

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. A pitch truss with a sloping or non sloping vertical interior ceiling detail. For many multi family projects floor and roof trusses joists span from unit wall to unit wall while interior non load bearing walls tend to fall near the center of the floor span. An example of a load bearing wall call be seen on the right.

If there are two plates refer to an engineer. Internal wall brackets are used to connect internal non loadbearing walls to roof trusses at maximum 1800mm centres. One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing. 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.

It can take various forms and often used for aesthetic purposes adding height and focal interest to the ceiling. To enable the roof truss to deflect under loads nails to the truss must be installed at the top of the slotted holes and not hammered home to allow a loose fit only. If the wall in question is parallel to the joists trusses it will likely not be load bearing.
