Truss

Definition

A truss is a triangular arrangement of structural members that reduces non-axial forces on the truss to a set of axial forces in the members, forming a structural framework of triangular units for supporting loads over long spans.

Purpose

The purpose of a truss is to provide strong, lightweight support for structures, distributing loads efficiently and allowing for long spans without the need for intermediate supports.

Examples of Use

1. Bridges: Trusses are used in bridge construction to support the roadway and distribute loads.
2. Roof Structures: Roof trusses provide support for roofing materials and create open, unobstructed interior spaces.
3. Building Frames: Trusses are used in building frames to support floors and roofs, allowing for large open areas.

Related Terms

• Beam: A horizontal structural element that supports loads.
• Girder: A large, primary beam that supports smaller beams and loads.
• Cantilever: A projecting beam or structure supported at only one end.

Notes

• Design: The design of trusses requires careful calculation to ensure they can carry the intended loads without excessive bending or deflection.
• Materials: Trusses can be made from wood, steel, or other materials depending on the application and load requirements.
