NiTi and reused pseudo elastic reinforcing bar for improved cyclic strains, energy dissipation, damping properties and earthquake resilience
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.
