Final answer:
In cold-formed steel framing, floor cantilevers should not exceed 25 feet for the specified buildings.
Step-by-step explanation:
In cold-formed steel framing, floor cantilevers for the top floor of a two- or three-story building or the first floor of a one-story building shall not exceed 25 feet (Option 4). It's important for architects and engineers to consider the limitations and structural requirements when designing buildings, especially in light of factors like potential seismic activity and wind loads that can significantly impact the stability of tall structures, such as skyscrapers with massive cantilevers like the Sky Park in Singapore.
