Bracing of Continuous Columns

It is generally accepted that bracing provides elastic support. As shown in this article, the lateral supports for the buckling condition of continuous columns depend onelasticity in three different ways: Case 1: Reactions are proportional to the deflections with respect to the original neutral axis. Case 2: Reactions are proportional to the lateral deflection with respect to the adjacent points of support. Case 3: Reactions are proportional to the relative displacement of successive supports.
