Fixed-End Beam

Definition

A Fixed-End Beam is a beam that is fixed upon a support which prevents its rotation.

Purpose

The purpose of a Fixed-End Beam is to provide structural support with increased stiffness and reduced deflection, ensuring stability in constructions where the beam's rotation must be restricted.

Examples of Use

• Bridges: Using fixed-end beams to provide rigid support for bridge decks.
• Buildings: Installing fixed-end beams in floors or roofs to reduce movement and enhance structural integrity.
• Retaining Walls: Employing fixed-end beams to resist lateral earth pressures.

Related Terms

• Cantilever Beam: A beam anchored at only one end with the other end projecting freely.
• Simply Supported Beam: A beam supported at both ends but free to rotate.
• Continuous Beam: A beam that extends over multiple supports without hinge connections.

Notes

• Fixed-end beams must be designed and installed correctly to ensure they can handle the imposed loads without excessive deflection.
• The supports for fixed-end beams must be sufficiently strong and stable to prevent rotation and movement.
