What is a beam that projects beyond its support but not enough to be a cantilever?

An overhanging beam is defined as a structural element that extends beyond its support but does not extend far enough to be classified as a cantilever beam. This type of beam is partially supported at both ends and has a portion that extends beyond one or both supports. The key characteristic of an overhanging beam is that while it does extend beyond its supports, it still relies on those supports for stability and load distribution, unlike a cantilever beam which is fixed at one end and free at the other.

In building construction, overhanging beams can be utilized in various scenarios to provide architectural features such as balconies or to support loads evenly distributed across their span, enhancing overall structural integrity while maintaining functional design. Understanding the definitions and distinctions of various beam types is critical for both construction and fire service professionals as they relate to safety, load management, and structural behavior during incidents.
