Roof Truss Bearing Points

It appears that the truss was too low once it spanned the high ceiling area and the clearance was elevated to create a vaulted ceiling at the top of the stairwell.

Roof truss bearing points.

Bearing cut or seat cut. Trusses are also marked at the load points when manufactured. One top plate and a space between the bottom chord of the truss and the top of the wall non load bearing. Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.

The point on the truss where the top and bottom chords intersect. While this article focuses on configurations we also have a very cool set of illustrations showcasing the different parts anatomy of roof trusses. Vertical distance between bearing and the uppermost point of the peak. 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.

Bearing must occur at a truss joint location. Roof trusses manufacturers terminology components of a truss. Chances are this is a non bearing wall. The roof structure and second floor structure defines largely where load bearing points are located.

If there are two plates refer to an engineer. The wall plate width see figure 7. Actually a quick way to determine if the wall is bearing is to cut hole at the top to see if it has one or two top plates. The cantilever dimension is measured from the outside face of the support to the heel joint.

Structural support of trusses usually walls normally with a timber wall plate. Some structures that span between these grounding points are known as load bearing walls beams headers trusses or lintels. A horizontal cut to the bottom of a sloping bottom chord usually the width of the bearing i e. That truss appears to only have two load bearing points.

Most exterior walls bear some load of a house while interior load bearing walls can typically be parallel to the roof ridge of the home and tend to run perpendicular to the floor joists. Cantilever that structural portion of a truss which extends beyond the support. The wood truss configurations for the actual truss design. I would still call the architect to verify.

Bearing widththe width dimension of the member providing support for the truss usually 3 1 2 or 5 1 2. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. Illustrated on this chart are a representative sampling.
