89. A two-story home has vertical studs, but none of its studs run the full height of the home. Instead, the studs used are only the height of the story on which they appear. What kind of framing does this describe?
Answer: A
Platform framing describes the construction method used in this scenario.
In platform framing, each story of a building is framed independently, with the studs only extending the height of that particular story. This method allows for easier construction and is commonly used in modern residential buildings.
A) platform framing
This option is correct as it accurately describes the construction method where each floor is framed separately with vertical studs that do not extend beyond the height of the story. Platform framing is characterized by this independent construction of each level, making it a popular choice for two-story homes.
B) balloon framing
Balloon framing is incorrect because it involves vertical studs that run continuously from the foundation to the roof, allowing for larger openings and fewer framing members. This method is not applicable to the described scenario where studs do not extend the full height of the home.
C) stud framing
While stud framing generally refers to the use of vertical studs in construction, it does not specifically describe the method of framing used in this scenario. Stud framing can be a component of various framing types, but it does not accurately capture the independent story structure of platform framing.
D) post and beam framing
Post and beam framing is not correct in this context because it involves the use of horizontal beams and vertical posts that create a structural framework, often leaving large open spaces without the use of studs. This method does not align with the description of studs only reaching the height of the story.
Conclusion
Platform framing is the definitive correct answer, as it perfectly matches the description of a two-story home with studs limited to each story's height. The other options fail to address the specific framing technique used, either by involving continuous vertical elements or by not being relevant to the given context.
