Technique applicable to new structures and when retrofitting older buildings
against earthquake risks by using:
Dampers to dissipate the energy
External cables to limit the inter-story drift
CBIST:
Cable Brace Isolation
SystemTechnology
Building protected with CBIST
Advantages:
Architectural design remains the same
Design improvement and simplification
No internal modification to the building
Increase of safety
No maintenance
Drift per story and acceleration are reduced significantly during an earthquake
Cost reduction compared to other techniques
Technology innovation
Few repair after earthquake
