Frame-in-frame design of structures against earthquake and wind loads using energy dissipative cushion dampers made of different metals

Description: The proposed system integrates a primary frame (either reinforced concrete or steel) with a secondary steel frame, interconnected via multiple energy-dissipative cushion dampers composed of various metals and shape memory alloys. These dampers, by virtue of their material composition and design, are capable of deforming to absorb and dissipate...

A novel steel-shape memory alloy hybrid damper for energy mitigation

Description: This invention introduces a novel hybrid cushion damper that leverages the strengths of both steel and shape memory alloy (SMA) for optimized performance in energy dissipation and self-centering. The damper features a unique design where steel and SMA components are combined using specialized bolt configurations. The steel part adopts...
