Which component is typically larger than a beam and helps distribute loads across a floor?

• A. Beams
• B. Girders
• C. Trusses
• D. Chase

Answer: (B)

In floor framing, the load from the floor system needs to be gathered and carried to the vertical supports. The larger, main horizontal member that sits beneath the joists and collects their loads is a girder. Girders are designed to carry heavier loads and span between columns or support walls, distributing those loads across a wider area to the building’s structure. That makes them larger than a typical beam and crucial for transferring floor loads efficiently. Beams support joists but are themselves supported by girders or columns, so they’re generally smaller than girders. Trusses are used for long spans with a triangular framework and can be substantial, but in standard floor framing the term that best fits “larger than a beam and distributes loads across a floor” is girders. A chase is just a duct/pipe passage and doesn’t participate in load distribution.
