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 seismic energy, thereby improving the structural integrity and resilience of buildings during earthquakes.

Key Advantages:

• Enhanced energy dissipation at lower load levels through the use of aluminum and copper cushion dampers.
• Increased structural resilience and self-centering capability due to the integration of shape memory alloys.
• Flexible connection options tailored to the frame material, ensuring robust integration.
• Proven effectiveness through extensive experimental campaigns, including large-scale shake table tests.

Problems Solved:

• Reduced structural damage during seismic events.
• Lowered repair costs and improved post-earthquake functionality due to self-centering capabilities.
• Increased safety and reduced downtime following an earthquake.

Market Applications:

• Seismic retrofitting of existing buildings and infrastructure.
• New construction in earthquake-prone areas.
• Civil engineering and structural design innovations.
• Earthquake resilience consulting and implementation.
