Vierendeel "Truss" (or Frame)

Definition

A rigid frame, used as a beam, assembled from parallel top and bottom chords tied together by vertical members.

Purpose

Vierendeel frames are used in structural engineering to create beams and frames with large openings, providing both aesthetic appeal and functional advantages by allowing unobstructed spaces without diagonal bracing.

Examples of Use

1. Modern bridges utilizing Vierendeel frames for their clean lines and open spaces.
2. High-rise buildings incorporating Vierendeel trusses for large, unobstructed floor plans.
3. Architectural designs where visual transparency and structural integrity are essential.

Related Terms

• Truss: A framework, typically consisting of rafters, posts, and struts.
• Beam: A horizontal structural element that withstands loads.
• Chord: The upper or lower member of a truss.

Notes

Vierendeel frames require precise engineering and construction to ensure stability and load-bearing capacity without the support of diagonal elements.
