In construction, what is the role of a beam?

The role of a beam in construction is fundamentally centered around supporting vertical loads. Beams are horizontal structural elements that carry and transfer weight from above them to vertical supports like walls or columns. They are critical in a building's framework for maintaining structural integrity and ensuring that loads from the roof, floors, or other overhead elements are distributed appropriately to prevent collapse.

While beams can sometimes play a role in framing elements for roofs or contribute to a building's aesthetic appeal, their primary function remains focused on load-bearing. Insulation, on the other hand, is not a role assumed by beams; rather, it is typically the job of materials specifically designed for thermal resistance. Understanding this fundamental role helps in the design and implementation of structural systems in construction.
