Observation of damage in seismic events has highlighted that collapse of infill walls in the out-of-plane direction may occur even for moderate intensity of ground motion. Different analytical models have been proposed in the last decades for the assessment of the out-of-plane response of infills and their applicability under different conditions has been checked also with experimental tests.

It is well known that dynamical systems that include devices based on shape memory alloys (SMA) can exhibit a wide spectrum of responses: periodic, quasi-periodic and chaotic motions. In view of the different types of possible applications, it is important to recognize the qualitative features of the system vibrations. To this end, various methods have been proposed in the literature and evaluated in different conditions.
