Island Tower Sky Club is a 145 meter tall, 42-story super high-rise. The tower comprises three slender connected buildings, each with a challenging aspect ratio of seven. It is the world's first super high-rise condominium with three connected towers.
A hybrid base-isolation system that utilizes four types of isolation is incorporated. The buildings are connected by three-tiered steel truss structures incorporating high-strain super-plastic alloy dampers, developed by Takenaka.

The three buildings are connected by"Sky Garden"aerial yards, built using the lift-up construction method. This allowed each yard to be built upon a lower yard and then lifted up to its designated position.
By connecting the buildings with Sky Gardens and combining base-isolation and motion-damping systems, both wind-induced and earthquake motions are reduced. (Movement in this sketch has been exaggerated for illustrative purposes.)
Viscous damper, oil damper and rubber damperSeismic Isolation is an effective means to reduce the effects of earthquakes and meet the needs of Business Continuity Planning (BCP) in facilities that manufacture semiconductors and electronic devices. The viscous seismic isolation system developed by Takenaka provides superb vibration absorbing performance during earthquakes of 3 to 5 on the Japanese seismic intensity scale as well as ensures an environment, free of microvibrations. The system combines a vibration-transmission-minimizing rubber bearing with a viscous damper for high vibration-energy-absorbing performance.
-good case study for my project because it gives real world applicative solution for high rise in one of the highest earthquake zones in the world, very applicable for California area.
