What is the minimum bearing required for the ends of floor joists on wood or metal?

1 inch
1 1/4 inches
1 1/2 inches
2 inches

The correct answer is: 1 1/2 inches

The minimum bearing required for the ends of floor joists on wood or metal is 1 1/2 inches. This specification is important for several reasons related to structural integrity and safety. A bearing of 1 1/2 inches ensures that the joists have adequate support at their ends, which helps distribute the load effectively across the supporting structure. When floor joists are properly supported, it minimizes the risk of sagging or structural failure over time. This measurement is commonly referenced in building codes and guidelines, reflecting a standard that has been established based on engineering principles and extensive testing. Therefore, adhering to this standard is crucial for ensuring the longevity and stability of the flooring system in residential construction.
