Estimation of load-carrying capacity of multi-layered plated structures

The load-carrying capacity of plated structures consisted of three-layered plates with metallic isotropic face layers and metallic or non-metallic orthotropic core is determined by means of four groups of methods, namely analytical–numerical methods, the effective width approach, numerical methods—finite element and finite strip methods as well as kinematical method based on principle of virtual velocities. Theoretical backgrounds of all applied methods are presented. Results of case studies concerning separated simply supported plate under compression and thin-walled girder under pure bending are discussed. Exemplary results of calculations are presented in diagrams. Some remarks derived from the comparative analysis of obtained results based on the methods under consideration are derived.
