【Abstract】 The damping mechanism of shape memory alloy(SMA)superelastic damping technology is introduced and a damper device based on SMA wires is developed for vibration control implementation of large bridges as well as high rise buildings.The proposed damper was characterized good energy dissipation mechanism.As a case study,two such SMA dampers were installed in a cable stayed bridge model to verify the effectiveness of the damper devices.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
