What is a push brace typically used for?

A push brace is typically used in situations where guys cannot be installed. This is particularly relevant in scenarios where the terrain or the design of the structure does not allow for the standard use of guy wires, which are typically employed to stabilize tall structures like poles or towers. Push braces serve as internal supports that help maintain the integrity and stability of these structures, allowing for proper alignment and resistance against lateral forces, such as wind or vibration.

In contrast, the other options do not accurately reflect the primary function of a push brace. While temporary support could be an aspect of how some braces might function, it is not their main purpose. Push braces are not designed to replace dead guys, which serve a different role entirely. Similarly, limiting their use to only during high winds fails to capture their ongoing necessity for stability at all times, not just under specific weather conditions.
