【Abstract】 This paper introduces one of constitutive relationship of Shape Memory Alloy (SMA). According to the advantage of various SMA dampers, a new SMA damper is developed. The proposed damper is characterized by good energy dissipation mechanism , and constructional detail of the damper is presented. Based on the time-history emulation analysis for frame, two results with SMA dampers and without SMA dampers are compared. The experimental results illustrate that the developed SMA dampers are very effective to reduce structural response and have great potential for use as efficient energy dissipation devices.更多还原
