What is the primary function of a beam in construction?

The primary function of a beam in construction is to support structural elements, which includes both roof and floor framing members. Beams are horizontal supports that bear the weight from above, distributing that load to vertical supports such as walls or columns. This critical role in load-bearing allows beams to maintain the integrity of the structure and ensure stability.

While the answer points to supporting floor framing members specifically, it’s important to recognize that beams can indeed support various parts of a building, depending on their location and design. They are essential in helping to manage and transfer loads from the roof or upper floors down to the foundation. While insulation and decorative elements are important in construction, they do not fulfill the fundamental load-bearing purpose that beams are designed for.
