What is a Cantilever Beam?

A rigid structural element known as a cantilever beam is supported at one end and is unsupported at the other. The cantilever beam can be built of steel or concrete, with one end cast or fastened to a vertical support. It is a horizontal beam structure, and the free end is exposed to vertical loads. A cantilever is built as an extension of a continuous beam in a building and a section of a cantilever girder in a bridge. It can be built using pre-stressing techniques or cast-in-place segmental construction.

Overhanging buildings can be built using cantilever technology without the need for additional bracing and supports. This structural component can give a building, tower, or bridge a special elegance. It is frequently employed in building construction.

Advantages and Disadvantages of Cantilever Beam

The following are some of the cantilever beam's main Advantages:

• Cantilever beams don't need assistance from the other side.
• Cantilever beams' negative bending moments balance the positive bending moments produced.
• Cantilever beams are simple to build.

The following are cantilever beam's Disadvantages:

• Large deflections are applied to cantilever beams.
• Moments are greater for cantilever beams.
• To remain stable, the construction must have sturdy fixed support or a back span.
