The use of friction bearing isolate developed by shape memory alloys wire toward earthquake resistant buildings and more sustainable

Seismic isolation systems are crucial for buildings to withstand earthquake loads and manage deformations. Shape memory alloys (SMA), like superelastic SMA, offer exceptional self-centring ability and dissipate seismic energy effectively. This study explores the hybrid use of SMA-based triple friction bearings (TFBs) for response control in standalone reinforced concrete structures. Parametric analysis compares the performance of SMA-based TFB systems with traditional TFBs, revealing reduced residual displacement in bearings (9%-17%) without significant increases in drift, displacements, and forces. This effectiveness in decreasing displacement and lateral deformation preserves efficacy and durability, safeguarding superstructures.
