Abstract
In the last few decades, increasing research efforts have been devoted to the definition of innovative seismic design philosophies aiming at reducing seismic-induced direct and indirect losses. For steel Moment Resisting Frames (MRFs), the use of Friction Devices (FDs) in beam-to-column connections has emerged as an effective solution to dissipate the seismic input energy while also ensuring their damage-free behaviour. Additionally, more recent research studies have revealed the benefits of replacing traditional full-strength Column Bases (CBs) with innovative CBs for both damage and residual drift reductions of steel MRFs. In this direction, an experimental campaign has been performed on a two-storey large-scale steel structure equipped with innovative Self-Centring CBs (SC-CBs). The present paper illustrates the preparatory work required for the specimen's design, the experimental program and the preliminary results. The tests' outcomes demonstrated the effectiveness of the SC-CB connections in minimising the residual drifts of the structure and in protecting the first-storey columns from damage.
