Which of the following is NOT included in wall-framing members of platform construction?

In platform construction, wall framing consists of various members that work together to create the structural walls of a building. Sole plates serve as the bottom component of the wall frame, providing a base to which vertical studs are attached. Top plates are similarly crucial as they cap the framing at the top, tying the wall together and adding strength. Headers are also an important part of the framing, as they support the weight above door and window openings.

Cripple studs, while pertinent to wall framing, are typically shorter vertical framing members placed above or below openings, but they are not considered primary framing members like sole plates, top plates, or headers. Instead, they serve to fill in gaps and maintain the structural integrity of a wall around openings. Thus, criple studs are included in the framing but not classified among the principal wall-framing members in the same way the other components are.

Therefore, while all items are related to wall framing, cripple studs are not considered one of the main structural elements in platform construction.
