The term "bracing" specifically refers to structural elements that are used to provide temporary support and stability to parts of a steel frame during construction. This is a critical function in erecting steel structures, as it helps maintain the integrity and alignment of the frame until permanent connections and supports are established. Bracing can be made from various materials and is essential in preventing movement and ensuring that the structure can withstand loads and environmental factors while being constructed.

In contrast, other terms like supporting refer more generally to elements that hold up structural loads, while bridging typically indicates connections that span spaces between two parts, often used in a permanent context. The term stub usually relates to short, leftover pieces of material that may not play a role in structural stabilization. Hence, bracing is the most accurate descriptor for what is needed to connect parts of a steel frame temporarily during construction activities.
