Continuous Beam

Definition

A continuous beam is a beam that is supported by more than two supports.

Purpose

The purpose of a continuous beam is to distribute loads more evenly across multiple supports, enhancing structural stability and reducing bending moments and deflections compared to simply supported beams.

Examples of Use

• Bridges often utilize continuous beams to span multiple piers, providing strength and stability over long distances.
• In multi-story buildings, continuous beams support floor loads across multiple columns.
• Industrial structures may use continuous beams to support heavy machinery and equipment over large areas.

Related Terms

• Simply Supported Beam: A beam supported at its ends but not fixed, allowing for rotation and deflection.
• Cantilever Beam: A beam anchored at one end and free at the other, projecting beyond its support.
• Fixed Beam: A beam with supports at both ends that prevent rotation, providing higher rigidity.

Notes

Designing continuous beams requires careful analysis of load distribution, support conditions, and potential points of maximum bending moments. This ensures adequate strength and performance under expected loads.
