What is the purpose of diagonal bracing in wall framing?

Diagonal bracing in wall framing is primarily used to prevent racking. Racking refers to the distortion of a wall frame due to lateral forces, such as wind or seismic activity. When these lateral forces are applied, they can cause the frame to shift or lean, compromising the structural integrity of the building. Diagonal braces are installed between vertical and horizontal members of the frame, creating a triangular shape that effectively resists these lateral forces.

The arrangement of diagonal bracing significantly enhances the overall stability of the walls, allowing them to maintain their shape and support the structure as intended. This is crucial not only for the safety of the building but also for ensuring it meets building codes and standards. By effectively counteracting racking, diagonal bracing plays a vital role in the overall durability and performance of the wall framing system.

The other options, such as supporting weight or reducing insulation costs, do not align with the primary function of diagonal bracing in structural applications. While aesthetic appeal may be influenced by design choices, it is not a fundamental purpose of bracing.
