Seismic Response Control for Steel Structure Using Shape Memory Alloy Damper

In order to use SMA to control the seismic response of structure,SMA damper was optimal designed in this paper,and calculation model for the ferfex fixing organization was introduced.The damping effects of 9-floor steel frame structure with forfex-type SMA damper under normal and uncommon earthquake were simulated and analyzed;the affect of angle parameter on damper performances was discussed.Analyze results indicated that the forfex-type SMA damper has favorable damping effect,and can meet the seismic design specification for different structures by adjusting properly angle parameter.
