What term describes the stress in a wood frame structure that allows part of the load from a weaker member to be distributed to adjacent members?

The correct term that describes the stress in a wood frame structure, allowing part of the load from a weaker member to be distributed to adjacent members, is often referred to in the context of "Extra fiber bending in repetitive members." This concept arises from the behavior of structural systems where multiple members work together to carry loads. When one member experiences stress, it can cause adjacent members to share in the load, effectively distributing the weight and reducing the risk of failure in the weaker member.

In wood frame structures, this is particularly pertinent since the properties of wood can vary within the same piece or between different members. By recognizing how load distribution occurs among repetitive members, builders can design more effective and resilient structures.

Other terms mentioned, such as compound bending or composite load distribution, do not specifically address the mechanism of load sharing in repetitive members. Secondary load bending, while a relevant concept in structural analysis, does not accurately capture the focus on the cooperative behavior of adjacent structural elements in the context provided in the question.
