【Abstract】 This paper introduces the basic characteristic and the constitutive model of Shape Memory Alloy(SMA),and set up its seismic response motion equation of tall building structures using passive control device and explores its principle and methods of passive control.It compare a non-control program and a program with traditional steel cables to a program.The result indicates that SMA has obvious damping,the seismic response of structure can be reduced significantly.更多还原
