What term identifies a component of a self-support tower?

The correct term that identifies a component of a self-support tower is the horizontal member. In the context of tower structures, horizontal members, often known as cross-bracing or horizontal supports, play a vital role in providing the necessary stability and support to maintain the integrity of the overall structure. These members connect vertical elements and distribute loads, ensuring that the tower can withstand various environmental forces such as wind and seismic activity.

Vertical members are also essential, but they primarily provide the height and upright support to the structure, while the base plate is a component that supports the entire tower at its base, connecting the vertical members to the ground. The foundation block serves as the foundational element, providing stability and anchoring the whole tower system securely to the ground. While all these components are crucial to the structure of a self-support tower, the horizontal member specifically is integral to its design and functionality.
