<jats:title>Abstract</jats:title><jats:p>The robustness of structures against severe seismic action is ensured by their global performance, in terms of <jats:italic>ductility stiffness</jats:italic> and <jats:italic>strength</jats:italic>, properly calibrated. The “<jats:italic>plastic</jats:italic>“ members of ductile Mild Carbon Steel ‐ MCS – (S235 to S355) will dissipate the seismic energy, acting as “s<jats:italic>tructural fuses</jats:italic>“, while the “<jats:italic>elastic</jats:italic>“ members, must be provided of adequate overstrength, to have the capacity to carry the supplementary stresses after the plastic hinges have been formed and the redistribution forces were occurred. For these <jats:italic>elastic members, High Strength Steels</jats:italic> (HSS), such as S460 to S690, might be used, provide them the necessary overstrength, without enhancing the stiffness, because that could unbalance the structural system. These structures, which combine HSS with MCS, are termed <jats:italic>Dual‐Steel</jats:italic> (DS). The braced frames can be equipped with detachable dissipative MCS members, which are acting as <jats:italic>seismic fuses</jats:italic>. In case of CBF, the <jats:italic>fuses</jats:italic> might be the <jats:italic>Buckling Restrained Braces</jats:italic> (BRB), while for EBF, the <jats:italic>links</jats:italic> could take this role. In case of MRF, <jats:italic>Steel Plate Shear Walls</jats:italic> (SW) can be used as <jats:italic>fuses</jats:italic>. To make possibly to replace the used <jats:italic>fuses</jats:italic>, the HSS <jats:italic>elastic</jats:italic> part of the structure, has the <jats:italic>mission</jats:italic> to re‐centring the structure after the earthquake. This is the subject of present paper.</jats:p>
