SMA recentering devices for seismic isolation of civil structures
Two similar full scale seismic isolation SMA prototype devices, with 600 KN maximum force and 200 KN supplemental recentering force were the final product of the MANSIDE (Memory Alloys for New Seismic Isolation DEvices) project funded by the European Commission. Exploiting the superelastic behaviour of NiTi wires, they have full recentering and some energy dissipation capabilities, as well as high resistance to large strain cycle fatigue and great durability. They can be used for both bridges and building structures. Their applicability is demonstrated by an experimental application made on a small building in Italy. The building was subjected to a release test, by moving it 150 mm and then suddenly releasing it to measure free oscillations. A description of the devices, their applicability and the relevant experimental tests is provided in the paper.
