Characterization and Fit to Seismic protection of shape memory alloys
The mechanical properties of shape memory alloys, used properly in seismic retrofit could achieve an efficient protection of structures subject to earthquakes. In this paper a series of experiments are carried out to characterize different materials given by various manufacturers. In the available literature there is no reference of Shape Memory Alloys used for Seismic protection, and the test results do not show clearly the main capacities of these materials, namely for the super-elasticity and the energy dissipation. Static and dynamic properties of SMA are given herein, and as the experiments show, a selection of materials were suited to our applications. Given that the dynamical behaviour is rate sensitive, an improvement of the shape memory device is also proposed, giving good results for future applications.
