In floor framing, tail joists over which length must be supported at the header by framing anchors?

In floor framing, tail joists require adequate support to ensure structural integrity and safety. When the length of a tail joist exceeds 12 feet, it becomes critical to provide additional support at the header using framing anchors. This requirement is based on building codes and structural engineering principles that help distribute loads effectively and prevent potential deflection or failure.

When tail joists are allowed to extend beyond this specified length without proper support, there may be an increased risk of bending or sagging, which can compromise the overall stability of the floor structure. Therefore, using framing anchors at lengths greater than 12 feet helps to maintain the necessary structural support and ensures that the floor framing performs as intended under various loads.
