Traditional buildings are conceived as a set of different construction layers with different roles, thus generating complex information to coordinate during rehabilitation and retrofitting. When architectural features are not a concern, such as in most of the social housing heritage, a new external envelope can be superimposed to the building in order to solve, with a single intervention, functional, architectural and, in particular, seismic problems. The new structure, connected to the existing building with shape memory alloys-based seismic devices, can prevent collapses and dissipate horizontal loads granting a calibrated operability. This paper shows the feasibility of the proposal through the numerical results of nonlinear static and dynamic analyses applied to two structural typologies, namely masonry and concrete frame with masonry infill, in different seismic zones. Finally, the method is verified for a real case study.
