Engineered Roof Trusses Load Bearing Walls

The span in short is the length of the bottom of the truss.

Engineered roof trusses load bearing walls.

By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself. They do this by means of top chords which are sloping members that extend from the peak of the roof to the top of the exterior walls at the eaves. Photograph the trusses draw them to scale take the pictures and elevation plan of the trusses to a reseller lumberyard and ask would a new truss like that be a clear span design if yes you can remove the wall use floating slotted clips between the top plate and truss bottom cord to reduce drywall cracking. No expert but a traditionally constructed roof needs some type of support in the form of a beam or load bearing wall in the house.

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. 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. Some spans have a lower rate per foot than others. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load.

Factors that affect truss pricing and cost. Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin. This is the distance of the bottom chord of the truss from outside overhang of bearing wall to outside of the other bearing wall.
