Recent researchof shape memory alloy in seismic resistance Song Xinlei1,a Huang Chengwei2,b , Wang Dan3,c Department of Civil Engineering, Kunming University of Science and Technology, Kunming 650500 China a249479199@qq.com, b994048762@qq.com, c 190271844@qq.com, Key Words：shape memory alloy；seismic resistance；passive control; active control；constitutive relation Abstract: Shape memory alloy has received widespread attention in seismic areas now, this paper introduce it develop in the field of earthquake in the past 5 years at home, mainly introduce the research in domestic of passive and active control, roughly summarized it in concrete girder bridge design and test, discussing the constitutive relations of SMA ,finally put forward the problems existing and development prospects .It indicate the direction of practical application in the future.
Introduction shape memory alloy (shape memory alloy, SMA) is the alloy having a low temperature in the initial shape and fixed by plastic deformation into another shape, by heating to a temperature above the critical and restored to the original shape of a alloys , the shape memory alloy is heated to their deformation characteristics can be divided into three categories: one-way shape memory alloy, two-way shape memory alloy, the whole memory alloy, the deformation characteristics shown in Figure 1 [1]Because of its durability, corrosion resistance, long life, large deformation can occur and has been widely used to restore its unique high damping, super elasticity and shape memory effect in engineering damping control function originally obtained more attention on the major developments in seismic engineering is the application of SMA and SMA drive smart passive dampers and concrete.
With the new cylinder type self resetting shape memory alloy damper Qian Hui (TRSMAD) the shaking table test of a three storey two span structure, which is arranged at the side of the underlying structure, studied the control of eccentric structure lateral torsional coupled vibration; Wang Lijun in order to study such as post earthquake permanent damage what reduction of shear walls, install SMA on a beam, with the time history analysis of the seismic response of a 12 story shear wall, analysis has good damping effect; Song Wali put forward a kind of multidimensional control can realize the damper, which uses elastic properties of ultra SMA, damper design can withstand level good, and torsion loads; Cheng Jiefang [3]simulation finite element installed Ni-Ti, and single cable plane cable arch bridge was analyzed with Midas/civil software, the results show that the installation of Ni-Ti cable can effectively reduce the arch of the longitudinal displacement and transverse torsional displacement

Thus, the dynamic analysis of RCS should be done first in LOCA case, getting interface loads of equipment, supports and civil works for their stress analysis and designs.
It is great significant for improving the RCS structural analysis and localization, there are powerful engineering application prospects and values.
It can be applied to practical engineering analysis, and will greatly improve the analysis efficiency.
