In balloon framing, the second floor joists rest on:

In balloon framing, the second floor joists rest on the ribbon, which is also known as the ribbon board or ribbon plate. This element is a horizontal framing member attached to the outside wall to which the second floor joists are connected. It plays a crucial role in the structural integrity of the building by providing a stable surface for the joists to rest on, ensuring that the load from the upper floors is properly distributed to the wall below.

The ribbon allows for a continuous framing system that extends the walls from the foundation to the second story, which is a characteristic feature of balloon framing. This method contrasts with platform framing, where each floor is built separately and rests on its own top plate. Understanding this key aspect of balloon framing helps builders recognize how the design contributes to the overall stability and frame of a structure.
