Bearing partitions perpendicular to joists must be offset a maximum distance equal to:

Bearing partitions that are perpendicular to joists must be offset a maximum distance equal to the joist depth to ensure proper load distribution and structural integrity. This guideline is essential because when a partition is positioned over a joist, it must transfer the load effectively without overloading the joist or creating a risk of structural failure.

By limiting the offset to the joist depth, the design ensures that the partition’s load is supported directly by the joist, minimizing the impact of any bending or lateral forces that might occur. If the bearing partition were offset beyond this limit, it could potentially lead to uneven load distribution, which might compromise the performance of both the partition and the joists over time, leading to sagging or failure.

This maximum offset provides a safe and standardized approach in construction and design, ensuring that buildings meet safety and structural standards. Other options that suggest greater offsets than the joist depth would not maintain effective load transfer, thus increasing the risk of structural failure.
