Abstract: The repair costs and downtime of a structure hit by an earthquake can be significantly reduced by adopting removable dissipative members and providing the structure with re-centring capability. These two concepts were implemented in a dual structure, obtained by combining steel eccentrically braced frames (with removable bolted links) and moment resisting frames. The bolted links provide the energy dissipation capacity and are easily replaceable, while the more flexible moment resisting frames provide the necessary re-centring capability. The solution will be validated by full-scale pseudo-dynamic test of a three-storey model of a steel structure with re-centring capability at the European Laboratory for Structural Assessment (ELSA) at the Joint Research Centre in Ispra within the framework of Transnational Access of the SERIES Project financed by the European Commission. The paper presents pre-test numerical simulations performed on a dual eccentrically braced frame with replaceable links. Both local performance of bolted links and overall system performance were investigated.
