What are "joists" used for in building construction?

To support the roof structure

To provide a framework for windows

To support the floor and ceiling structures

Joists are horizontal framing members used in building construction primarily to support the floor and ceiling structures. They are critical components that help distribute loads evenly across a building, ensuring structural stability and integrity. When installed, joists create space between them that allows for insulation and other systems, such as plumbing and electrical.

In the context of a building, the primary role of joists is to form a framework that carries the weight of objects placed on floors and ceilings, thereby transferring these loads to the supporting walls or beams. This makes them essential for creating safe and durable living and working spaces.
