Attic Trusses Resting On Non Bearing Wall

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.

Attic trusses resting on non bearing wall.

We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin. An example of a non load bearing partition wall can be seen on the left.
