Final answer:
The distance between points where a structural member is braced against buckling is termed the bracing interval, which is essential for structural integrity.
Option A, Bracing interval is correct.
Step-by-step explanation:
The term that describes the distance between the points at which a structural member is braced against buckling in a direction normal to its length is known as the bracing interval. Buckling span, sway distance, and stability length are other terms that relate to the stability and support of structures, but bracing interval specifically refers to the spacing of bracing elements that enhance the buckling resistance of a member. Ensuring that bracing intervals are adequately designed is essential for the structural integrity and stability of various engineering applications, such as buildings, bridges, and towers.
In contrast, options B, C, and D are not commonly used terms in this context. The Buckling Span is not a standard term, and both Sway Distance and Stability Length are not widely recognized in structural engineering terminology.
In conclusion, the correct term for the described distance is the Bracing Interval (Option A).
