Which type of beam is supported in three or more locations?

A continuous beam is defined by its support at three or more locations. This type of beam spans between multiple supports, allowing it to distribute loads more effectively and reduce deflection compared to simpler beam configurations. By being supported at several points, continuous beams can handle greater loads and stabilize structures, making them particularly useful in building construction where long spans without intermediate support are needed.

In contrast, a cantilever beam is supported at only one end, while a simple beam typically has support at two endpoints. An overhanging beam extends beyond its supports at one or both ends but does not rely on multiple intermediate supports. The unique capability of continuous beams to distribute loads across multiple supports is essential for many structural applications, enhancing both safety and structural integrity.
