Final answer:
Bridging becomes necessary for joists that exceed a depth where lateral movement is a concern, commonly at depths exceeding 12 inches, based on various building codes related to construction engineering.
Step-by-step explanation:
The question regarding whether bridging is required by code for joists depending on their depth relates to building codes in construction engineering.
Bridging, which reinforces floor joists to prevent them from moving laterally, is not usually specified by building codes for shorter joist spans. However, for joists that exceed a certain depth, bridging becomes necessary to ensure structural integrity. While the specific depth may vary by local codes and standards, a common requirement is for joists that exceed 12 inches in depth to have bridging or other lateral support.
In engineering, bridging is a technique used to provide additional support to long joists in a floor or roof system. It involves the installation of perpendicular pieces of lumber between the joists to reduce their span and prevent them from twisting or sagging.
Bridging is not generally required by code unless the joists exceed a certain depth. The specific depth that triggers the requirement for bridging may vary depending on the building code and the specific application.
For example, in some codes, bridging may be required when the joists exceed 2 inches in depth.
