Structural engineering

Sideways drift of a building frame under load

In structural engineering, sway is the lateral deflection of a building frame, the sideways movement of the tops of columns relative to their bases under horizontal loads such as wind or earthquake, or under unsymmetrical gravity loading. Whether a frame is free to sway decides how its members are analysed and braced: a sway frame develops additional second-order moments as it leans, whereas a braced, non-sway frame is held against this drift. McCormac and Csernak's Structural steel design treats sway and non-sway frames and their effective lengths. The referent is a deflection of a structure under load, unrelated to a ship's sideways motion beyond the shared idea of leaning sideways.[1]
