Which term refers to smaller structural supports that can span between beams?

The term that refers to smaller structural supports spanning between beams is joists. Joists are typically horizontal members used in construction to support a ceiling or floor. They provide structural support by distributing loads across the beams beneath them, allowing for spaces between beams to be effectively utilized for flooring or ceiling installation.

In contrast, columns are vertical structural elements that support loads from above and transfer them down to the foundation. Girders are larger beams that support joists and columns; they are primarily responsible for carrying heavier loads over longer spans. Piers are vertical structures that support the weight of a building and typically extend down to the ground or foundation, but they do not span between beams. Thus, the specific role of joists in bridging the gap between beams makes this term the most appropriate in this context.
