Let-In Bracing

Definition

Diagonal bracing nailed into notches cut in the face of the studs so as to avoid an increase in the thickness of the wall.

Purpose

Let-in bracing provides lateral stability to wood-framed walls, preventing them from racking or shifting under lateral loads such as wind or seismic forces. It is an essential element in maintaining the structural integrity of framed buildings.

Examples of Use

• Residential framing: Providing stability to the walls of homes constructed with wood framing.
• Light commercial buildings: Used in the framing of small commercial structures to ensure stability.
• Retrofits: Adding bracing to existing structures to enhance their resistance to lateral forces.

Related Terms

• Shear Wall: A wall designed to resist lateral forces and provide structural stability.
• Diagonal Bracing: Bracing that runs diagonally between framing members to prevent movement.
• Racking: The distortion of a rectangular frame into a parallelogram due to lateral forces.

Notes

• Proper installation of let-in bracing is crucial to its effectiveness; it must be securely fastened and correctly angled.
• Building codes often specify requirements for bracing in wood-framed construction.
• Regular inspection can help identify any damage or issues with bracing that might compromise structural stability.
