Research on Different Applications of SMA in Seismic Resistance of Building Structures

SMA(Shape memory alloys) are unique materials with many excellent properties, such as wear resistance, corrosion high power/weight ratio and biocompatibility, damping, shape effect, super elasticity, etc. In civil engineering, scientists try to use the advantages of SMA by making it into different components they have already made some types that bracing, constrains RC columns, ring springs base isolation bearing. All these can make contributions seismic therefore, this article mainly focuses on contribution bracings columns resistance structure relationship between improvement their own performance SMA.
