GNGTS 2017 S essione 2.3 447 and damping properties of VE devices, since part of the incoming seismic input energy can be preliminary dissipated. As a result, the UGCW and the steel frame are potentially subjected to a reduced seismic impulse, compared to the same building with fully rigid brackets. Conclusions. In this paper, the feasibility and potential of special mechanical joints interposed at the interface between a given multi-storey primary building and a traditional unitized glazing curtain wall (UGCW) have been investigated via accurate Finite-Element (FE) numerical models, under seismic events. Based on properly designed fasteners able to introduce additional flexibility and damping capacities in the traditional building, the maximum effects and benefits of such connectors have been shortly emphasized via a case study of technical interest, both in terms of global performances as well as local and component behaviour for the building object of investigation, giving evidence of the potential of UGCWs acting as distributedTMDs for multi-storey buildings under hazards. It is hence expected, based on current research outcomes partly emphasized in the paper, that the same design concept could be further calibrated and optimized, as well as that related design criteria could be fully implemented towards the definition of practical tools for designers.
