Diagonal

Definition

A Diagonal is an inclined member of a truss or bracing system used for stiffening and/or wind bracing.

Purpose

The purpose of a diagonal member is to enhance the structural integrity of trusses and bracing systems. It helps distribute loads and resist lateral forces, contributing to the overall stability and strength of the structure.

Examples of Use

1. Roof Trusses: Incorporating diagonal members in roof trusses to support the weight of the roof and resist wind forces.
2. Bridge Construction: Using diagonals in truss bridges to distribute loads and provide rigidity.
3. Building Frames: Installing diagonal members in building frames to improve resistance to seismic and wind loads.

Related Terms

• Truss: A structural framework of beams forming a rigid shape, often incorporating diagonal members for stability.
• Stiffening: The process of making a structure or component more rigid to resist deformation.
• Wind Bracing: Structural elements designed to resist wind loads and prevent lateral movement.

Notes

• Diagonal members are critical in various structural systems, especially in areas prone to high winds or seismic activity.
• The design and placement of diagonal members must be carefully planned to ensure maximum effectiveness.
• Diagonal members can be made from materials like steel, wood, or reinforced concrete, depending on the application.
