This paper presents an improved constitutive equation of frame in the context of continuous medium technique. This improved constitutive equation, which is a consistent formulation of column global bending, is applicable to a complete class of frameworks including the ideal shear frame panel, for which the beams are assumed to be rigid, and the associated column system, for which the rigidity of beams is negligible. Global buckling and second‐order effects of the frame structure are discussed. The main results can be extended to other types of lateral stiffening elements as built‐up columns. A worked example is presented in order to compare the main results with those obtained by the classic matrix method. Copyright © 2007 John Wiley & Sons, Ltd.
