WebMar 17, 2024 · Stability is a property of a structure to keep its initial position or initial deformable shape. Stable structure will regain to its original state if any disturbed factor, which changed the initial state, is removed. A structure subjected to compressed loads may be disturbed from initial equilibrium state by, for example, a small lateral load. WebThe subject of Chapter 4 is the elastic and in-elastic stability limit of planar beam-columns.
