Abstract:The self-rehabilitation properties of intelligent concrete structures reinforced with superelastic SMA strands are experimentally investigated. The influence of superelastic SMAs on the damping ratio of concrete columns is studied through initial displacement method. Then, the seismic responses and the self-recentering capability of SMA concrete structures are analyzed. The results show that the intelligent concrete beams have good self-rehabilitation capabilities and the SMAs can be utilized as inner energy dissipation devices to change the damping ratio of concrete members or structures for structural vibration suppression. Moreover, superelastic SMA reinforced concrete structures have less horizontal and torsional responses and excellent self-recentering capabilities compared to the reinforced concrete structures without SMAs. ? 2010 ASCE.
