How many inches of bearing are required for the ends of floor joists resting on structural supports?

2 inches
3 inches
4 inches
5 inches

The correct answer is: 3 inches

The requirement for how many inches of bearing are needed for the ends of floor joists resting on structural supports is an important aspect of ensuring proper load distribution and structural integrity. The standard stipulation is that a minimum of 3 inches of bearing is necessary. This dimension allows for adequate support to prevent joist failure and to help transfer loads effectively to the supporting elements below, such as beams or walls. Having at least 3 inches of bearing helps to ensure that the joists are securely positioned and minimizes the risk of shifting or slipping, which could potentially lead to structural instability. The requirement is based on both safety and performance considerations in residential construction. This is why the choice indicating 3 inches is the correct answer in the context of residential building codes and engineering practices.
