Document Type: Journal Paper

Abstract: 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.
