The supplementation of shape memory alloy (SMA) to rubber bearing has been propounded to be a greater alternative to the conventional high damping rubber bearings (HDRB) under near-fault earthquakes. A comparison between responses of a building subjected to HDRB without SMA and with SMA is demonstrated for near-fault, far-fault and fling type of ground motions. The present study substantiates the significant reduction in the residual base isolator displacement and base shear of a multi storeyed building when subjected to SMA supplemented HDRB isolator under considered ground motions.
