Study of a New Type SMA Damper
In this paper, a new type SMA damper making use of SMA wire was designed. When the damper was in a tensile, compressed or tensional condition, the SMA wire is always in the condition of tension. The passive energy dissipation control of seismic vibration makes use of the super elasticity and high damping of tensile SMA wire. On the basis of the study of a 10-story building, five groups of the placement of the damper are used in time-history dynamic analysis .By contrasting the five different results, the influencing rules of the placement of the damper on seismic response of the structure can be concluded.
