Beams are structural elements that deliver loads perpendicular to their length, creating bending moments. Which term best describes such elements?

• A. Columns
• B. Slabs
• C. Beams
• D. Braces

Answer: (C)

Beams are the structural members designed to carry loads that act across their length, which induces bending moments inside the member. When a load hits a beam perpendicularly to its axis, the beam resists by bending, creating tension on one side and compression on the other, with a moment diagram showing how the bending varies along its span. Columns, in contrast, primarily resist axial compression along their length and don’t rely on bending for their main load path. Slabs are flat horizontal panels that distribute loads to supports, often functioning as a floor or roof deck rather than as the primary bending member. Braces are diagonal elements that provide lateral stability and resist shear and buckling rather than primarily bending under transverse loads. So the term that best describes elements delivering perpendicular loads and developing bending moments is beams.
