Abstract
The presented experimental results demonstrated the ability of NiTi and reused NiTi reinforcing bar to undergo cyclical strains, showing an improved cyclic, energy dissipation, damping properties and a better potential for the use as shape memory alloys (SMAs) for seismic mitigation and earthquake resilience. Narrow hysteresis of 12.7 mm NiTi bar exhibits a perfect superelasticity with strain recovery capacity of 98.21%, while the reused NiTi exhibits the highest energy dissipation with a wide hysteresis of up to 99.95%. The strain recovery capacity increases with a decrease of the bar size.
