What framing construction utilizes closely spaced members spanning between structural elements?

The use of closely spaced members spanning between structural elements is characteristic of joist framing. This type of framing involves horizontal members called joists, which are typically set at regular intervals to support flooring or roofing materials. Joists provide the necessary structural support by distributing loads across their spans to the beams or walls beneath.

In joist framing, the spacing and sizing of the joists are crucial for ensuring adequate support and stability for the structure they are intended to carry, such as floors, ceilings, or roofs. This method allows for effective load transfer and is a common technique used in residential and some commercial construction.

The other framing types mentioned serve different structural roles or use different configurations of members. For instance, beam framing typically relies more on beams as primary supports, often leading to wider spacing with fewer framing members visible. Platform framing, while also using vertical studs and horizontal elements, has a specific methodology of stacking frameworks that isn’t strictly reliant on closely spaced joists. Post and beam framing utilizes larger structural posts and beams, which often results in open spaces and less frequent mini members compared to the closely knit arrangement of joists.
