In structural framing, what does a stringer primarily support?

In structural framing, a stringer primarily supports stairs. Stringers are the inclined supports that define the shape of a staircase and bear the load of the steps. They run along both sides, or sometimes in the middle, of the staircase and provide stability and strength to the construction. The design of stringers is essential in ensuring that the stairs are safe and can support the weight of people using them.

Stringers are specifically tailored to accommodate the rise and tread of the stairs, ensuring proper alignment and safety for foot traffic. While floor joists, roof rafters, and wall studs serve important roles in the overall structure of a building, they do not have the specific function of supporting the stairs as stringers do. This distinguishes the role of stringers in a stairway framework from other structural components in a building.
