The paper presents the development of a study on low cost seismic protection devices to put in place at the joints of prefabricated structural systems with the aim of improving their seismic response. In particular, this phase of the research focuses on the optimisation of protection devices used on two-dimensional mono-and multi-storey frames. A comparative analysis of the seismic response of the systems varying the mechanical characteristics of the devices was developed. The friction-type protective devices adopted were installed at the beam-column and column-foundation interfaces. The performed analyses show a significant improvement in seismic response, in terms of both reduction of stresses and increase of dissipative capacity.
