Abstract

A methodology for the advanced analysis of plane steel frames taking into consideration both geometrical and material nonlinearities is presented. Geometrical nonlinearity in the form of member and frame instabilities is accounted for by the use of fictitious joint loads derived from the geometrical stiffness matrix of the structure. Material nonlinearity in the form of cross-section plastification and progressive member yielding is accounted for by the use of an inelastic member flexural rigidity formulated from a set of inelastic cross-section moment-curvature-thrust equations. The validity of the proposed approach is demonstrated by comparison with other established second-order inelastic frame analysis methods.
