Which framing elements are used in the construction of floors and ceilings?

In construction, joists are specifically designed to support floors and ceilings by spanning the space between walls or beams. Joists are horizontal members that distribute the load of the floor or ceiling and are typically made from wood or engineered materials. They create a framework that provides stability and strength, allowing for proper weight distribution.

Studs, while essential for vertical wall framing, are not used for floors and ceilings but rather form the vertical structure of walls. Beams are larger horizontal members that support the load from above, but they do not extend over the same distances as joists and are typically used in conjunction with joists to provide support in larger spaces. Trusses, on the other hand, are structural frameworks used primarily in roof construction to support loads over a wide area, rather than specifically for floors or ceilings.

Therefore, when discussing the specific framing elements that are responsible for the construction of floors and ceilings, joists are the correct choice as they directly serve that purpose in the structural framework.
