The paper presents results of the comparative theoretical study into plastic strength of thin-walled plated structures (plates and columns) using two different approaches: energy method and equilibrium strip method. Two types of members, a thin plate and a channel section column subjected to compression, were under investigation. Numerical results obtained using both methods, together with FE simulation are presented in load-deformation diagrams. Experimental verification of theoretical analysis (using two methods under investigation together with standards strength predictions) focused on stub columns (lipped channel sections) is presented.
