DEFINITION

Classification: 52/724.1

Having feature resisting transverse loading (e.g., beam):

(under subclass 721.1) 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.).
