A single-storey reinforced concrete precast building was retrofitted firstly with RC jacketing of columns, and then with two energy dissipation devices, namely a friction rotation damper for beam-tocolumn connections and a bracing system with dissipative sacrificial elements. Once proved that both the investigated retrofitting solutions allow the structure to withstand the seismic demands at the life safety limit state, the environmental impact of both strategies was evaluated and compared quantitatively, accounting for multiple life cycle phases of each retrofit component. The innovative strategy with dissipation-based devices resulted to be more environment-friendly, under a life cycle perspective, than the traditional RC jacketing.

Abstract
A single-storey reinforced concrete precast building was retrofitted firstly with RC jacketing of columns, and then with two energy dissipation devices, namely a friction rotation damper for beam-tocolumn connections and a bracing system with dissipative sacrificial elements. Once proved that both the investigated retrofitting solutions allow the structure to withstand the seismic demands at the life safety limit state, the environmental impact of both strategies was evaluated and compared quantitatively, accounting for multiple life cycle phases of each retrofit component. The innovative strategy with dissipation-based devices resulted to be more environment-friendly, under a life cycle perspective, than the traditional RC jacketing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
