What is the basic concept of platform framing?

The basic concept of platform framing involves constructing each floor independently from the walls below. In this method, the floor joists are laid out on top of the walls, and the walls of each floor are built up directly onto the completed floor below. This approach allows for a process where the framing of each story can be efficiently constructed without needing to rely on the structural integrity of the walls below until the entire assembly is complete.

This technique is significant for several reasons. It simplifies the construction process, as each floor can be framed without needing to bring in additional support from below, and it also allows for more straightforward adjustments or modifications to individual floors if necessary. Additionally, by constructing each floor independently, builders can create more complex designs while also improving overall stability, as the load distribution occurs at each level.

Other options may suggest methods that either do not align with the principles of platform framing or represent an entirely different framing approach, thereby lacking the flexibility and advantages that independent floor construction provides in platform framing.
