  • Promotion of plastic design for steel and composite cross sections: new required conditions in Eurocodes 3 and 4, practical tools for designers


A new single criterion called rotation capacity quantifies a profile's capacity to develop a plastic hinge without discrimination for high steel strengths. The rotation capacity of plastic hinges has many parameters, including geometrical and mechanical characteristics of the cross-sections, ductility, deformation range, and local buckling problems. Currently, the more competitive plastic design is often excluded from the market because guides and practical tools evaluating available rotation capacities of cross-sections and required rotation capacities for different structures are not available. The aim of this research was therefore to determine the available rotation capacities for composite cross-sections of different steel shapes and grades, to determine the required rotation capacities for different types of structures, and to introduce new rules of plastic analysis. It is hoped that this will make steel and composite cross-sections more competitive, thus increasing their market share.
