Serial Information: Transactions of the American Society of Civil Engineers, 1961, Vol. 126, Issue 1, Pg. 176-193

Document Type: Journal Paper


Method of analyzing elastic stability of rigid frame structures subject to sidesway; energy method is applied to assumed frame deformation compatible with its restraints; assumed deformations are chosen so that compatibility may be achieved by one standard moment distribution; formulas are given and presented in graph form; two examples are compared to results obtained by more rigorous methods.
