SMA smart control device and analysis on seismic control of structure

XING De-jin,LI Zhong-xian(School of Civil Engineering,Tianjin University,Tianjin 300072,China)  
In order to get a good seismic control device for structure,a new SMA smart control device based on the change in the elastic modulus at different temperature is designed.The equations of output force and equivalent stiffness are also presented.The simulation analysis on seismic response of three-floor frame at the three states of without control,active control,SMA smart control,is carried out.The results show that the SMA smart device can reduce the seismic response of structure effectively,whose control effect is very close to active control.It is a good control device for structure.
