What kind of beam is supported at two points near its ends, with no additional support for overloads?

The type of beam described in the question is recognized as a simple beam. A simple beam is typically supported at two points close to its ends, allowing it to span the distance between those supports without any intermediate support. This configuration is significant because it is widely used in construction for its straightforward design and easy installation.

In this scenario, the absence of additional support for overloads indicates that the beam is solely relying on its end supports to bear the load. This places importance on how the beam is designed and engineered to manage bending moments and shear forces that occur when loads are applied.

The nature of a simple beam makes it ideal for many applications in building structures, as it can efficiently support loads in a straightforward manner and is easily analyzed using basic principles of mechanics. Understanding how simple beams function is essential for fire inspectors and other professionals in ensuring that building structures conform to safety standards and can withstand expected loads.
