This research has shown that the requirements of Eurocode 3 for the plastic design of a frame structure are not representative of the real behaviour of the plastic hinge formation. In the first part of this research, 5 three point bending tests of an HEB 200 profile were simulated with the nonlinear finite elements program FINELG. These simulations showed the influence of the steel grade, the initial global and local deformations and took into account the fillets in the numerical model on the rotation capacity of the beam. The numerical simulations have been calibrated in practical tests. In the second part of this research, 5 simple frame structures were simulated with the nonlinear finite elements program FINELG in order to determine the required rotation capacity of a structure. The numerical simulations have been calibrated with practical tests. In the third part of this research, a parametrical study on hypothetic steels has been performed in order to demonstrate that the requirements given in Eurocode 3 are very conservative. In conslusion, a new method is proposed which allows one to check the possibility of a plastic design of a structure.
