Abstract
A formulation of the stability problem for tall unbraced frames, deformed beyond their elastic limit, has been developed using transfer matrices. A linear incremental solution procedure allows the monitoring of plastic hinge formation and the resulting reduction of the member stiffness until the critical load is located. The most important second order effects arising from large deformation have been accounted for. Simple modeling of inelastic behaviour has been adopted although further refinement of the formulation at no significant computational cost is indicated. Extensive application of the developed computer algorithm and comparison of its predictions with other analytical results confirms the validity of the proposed method of solution.
