Multi storey RC buildings may undergo catastrophic damage when they are subjected to severe earthquakes. Several studies have been carried out by various researchers in the field of construction of earthquake resisting structures. However super elastic shape memory alloys play a vital role when they are used in civil engineering domain. Present study is carried out on implementation of Iron based and Nickel titanium shape memory alloys in RC structures as rebar. Twenty storey building is modelled with and without shape memory alloys with different locations of shear walls and they were subjected to seismic analysis (Response spectrum and Time history) for both fixed base and flexible base. Comparative study is carried out for all the models with Iron based SMA, Ni-Ti SMA and Conventional Steel. Results obtained from the analysis shows that the deformation is lesser for Iron based SMA followed by Ni-Ti SMA as compared to Conventional Steel. Hence use of SMA as a smart material in RC buildings results in greater resistance against the earthquake effects. Keywords: shape memory alloy, super elasticity, Iron based shape memory alloys, Nickel titanium shape memory alloy.
