Product Description
Unless prevented, sidesway buckling will preclude the most efficient use of a column. A better utilization of these members can be realized by providing diagonal bracing (as shown in Fig. 1) or shear walls. In many instances non structural building elements, curtain walls for example, can also provide the necessary stiffness against sidesway buckling. In Sect. 1.8 of the 1963 Specification of the American Institute of Steel Construction a braced frame is defined as a structure where lateral stability is provided "by diagonal bracing, shear walls, attachment to an adjacent structure having adequate lateral stability, or by floor slabs or roof decks secured horizontally by walls or bracing systems parallel to the plane of the frame." In contrast, an unbraced frame is a structure which depends upon its own bending stiffness to furnish the necessary lateral stability.
