For floor joists supported by masonry walls, the required end bearing distance is 3 inches. Which option represents this requirement?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 4 inches

Answer: (C)

The requirement for an end bearing distance of 3 inches for floor joists supported by masonry walls ensures that the joists are properly secured and can carry the loads they are intended to bear. A minimum bearing distance of 3 inches provides enough support and stability for the joists, helping to prevent issues such as deflection or even structural failure. This standard is important for maintaining the integrity of the floor system and ensuring safety within a building. In this context, the other options do not meet the necessary requirements, as they represent insufficient bearing distances that could compromise the structural support provided by the masonry walls. Thus, the chosen answer accurately reflects the building code requirements for proper end bearing of floor joists.
