What does the term "joist" refer to in construction?

The term "joist" specifically refers to a horizontal framing member designed to support a floor or ceiling. Joists are key structural elements in building construction, as they provide the necessary support for loads imposed on the floor or ceiling system, ensuring stability and structural integrity.

When discussing the role of joists, it's important to consider their arrangement, spacing, and the materials used. Joists can be made from various materials, including wood, engineered wood, or metal, and are usually spaced at regular intervals to provide adequate support while allowing for the installation of flooring or ceiling systems above.

By understanding the function of joists, one gains insight into the overall construction process and the importance of proper framing techniques in building design to maintain safety and performance in a structure.
