Deformed memory alloys due to special behaviors such as superelastic behavior (complete recovery of strain during loading and unloading in the form of a hysteresis curve) and memory behavior (recovery of strain during heating due to phase transformation from stable phase to low temperature to stable phase At high temperatures) has attracted the attention of researchers in the last decade. In addition to the above behaviors, these materials have other suitable properties such as high resistance to fatigue and corrosion, stability of its behavior-strain and energy dissipation ability. One of the ways to manage damage in the structure and reduce seismic needs is to use rocking systems. In these systems, relative motion occurs mainly between the legs of the columns and their corresponding foundations, where energy absorbers are made. In the rocking motion of the body, the structure deforms to an elastic level and moves almost as a rigid body, and after the earthquake, the weight of the building causes the structure to return to its original place.
