The goal of seismic response modification is to elicit more favourable behaviour from structures during earthquakes. A popular means for this modification is through the use of energy dissipation devices (EDDs), which effectively lower the seismic demand on main structural components by absorbing a portion of the seismic input energy. This energy is often absorbed through the yielding of metallic components within these devices. Examples of traditionally used metals are steel and lead which exhibit bilinear hysteretic behaviour. The introduction of shape memory alloys (SMAs) into the realm of seismic energy dissipation has occurred fairly recently and has occurred in large part due to their exceptional characteristics for earthquake engineering applications, including hysteretic properties. SMAs exhibit flag-shaped hysteretic behaviour creating the potential for relatively simple yet effective EDDs.
