Class Information
Number: 52/724.1
Name: Static structures (e.g., buildings) > Shaft (i.e., elongated rigid structure) > Stone-like component (e.g., concrete, etc.) > Having feature resisting transverse loading (e.g., beam)
Description: Structure comprising an elongated, rigid construction of great length compared to its width and depth which includes a nonuniform or eccentric reinforcement, or is particularly shaped in cross-section to add rigidity and resist force applied transversely to its longitudinal axis (e.g., girder, joist, etc.).
