This device was presented by Papadopoulos et al [1] and has the advantages to (i) provide add itional stiffness as well as (ii) absorption of seismic energy, (iii) provide control of the axial forces that are developed at the diagonal steel rods. Last but not least, it has the ability to retain the plastic displacements to a desired level. The first step was to model and analyze the group of superimposed blades in order to ascertain its behavior under monotonic loading, increased step by step until the collapse. To that purpose, Finite Element (FE) models of the system were developed and analyzed using the software ABAQUS. Parametric investigation was conducted to define the optimum combination of number and thickness as well as their elastoplastic properties. Furthermore, the group of superimposed blades was modeled and analyzed under quasi static cyclic loading, in order to ascertain its behavior to absorbed seismic energy. In addition, numerical results were compared with the same experimental so as to validate the model in the software ABAQUS.
