The maximum offset distance for bearing partitions from supporting elements is determined by:

The maximum offset distance for bearing partitions from supporting elements is determined by joist depth because joist depth directly influences the load distribution capabilities and structural integrity of the system. When a bearing partition is offset from supporting elements, it is critical to ensure that the loads are effectively transferred to the support system below.

Joist depth plays a crucial role in this by defining how much load a joist can carry while maintaining its structural performance and compliance with building codes. A deeper joist generally offers better load-carrying capacity and bending resistance, allowing for greater flexibility in the placement of partitions without compromising structural stability.

Thus, understanding the joist depth allows inspectors and builders to accurately assess the maximum allowable offset distance, ensuring that the building's design is safe and sound. The other options may relate to aspects of construction or design but do not specifically dictate the offset distance as directly as joist depth does.
