<jats:title>ABSTRACT</jats:title><jats:p>The ongoing research project SEMNAL‐MRD (Seismic Protection of Engineering Structures through Dissipative Braces of Nano‐Micro Magneto‐Rheological Fluid Dampers), aims to develop a seismic protection system employing a semi‐active structural control system. The most promising devices appear to be magneto‐rheological (MR) dampers. The current paper presents a case study related to the seismic response of multi‐storey frames equipped with dampers. The paper also describes the typology and working principle of MR dampers. Furthermore, the innovative solution for the current MR damper of composite nano‐micro MR fluid of passive/semi‐active control is presented in terms of technical solution and principle scheme. The experimental and numerical investigation program, developed for the characterization of the MR damper prototype of 10tf capacity, is described. The experimental investigations are to be performed on the MR damper, and respectively on the brace‐damper assembly, for which conventional as well as buckling restrained braces will be considered. Current outcomes of the ongoing experimental and numerical investigations, and the main conclusions are finally presented.</jats:p>
