In this study, the feasibility and potentiality of a novel design concept is explored by means of small scale experimental tests and Finite-Element numerical simulation. Taking advantage of the intrinsic potentiality of Shape-Memory Alloys wires able to work as adaptive actuators when subjected to joule heating, a 'smart-GFRP' concept consisting in Glass-Fiber-Reinforced-Polymer (GFRP) structural members with a SMA reinforcement is preliminary assessed. As shown, as far as the working temperature increases, important structural benefits can be achieved in terms of overall performance of the proposed composite systems. The potentiality of the same design concept is then further assessed by means of a practical calculation example.
