Cantilever column systems are seismic force-resisting systems in which the lateral forces are resisted entirely by columns that act as vertical cantilevers. Cantilever columns provide a simple alternative to a moment frame, braced frame, or shear wall for a variety of low-rise structures. In particular, they are useful in low-rise light-frame construction of two stories or less in combination with other structural systems to provide resistance along an independent line of resistance, as may be needed for an addition to an existing building. Cantilever column elements currently compete with proprietary prefabricated shear panels and proprietary light-gauge braced elements in lightframe shear wall systems.
