Introduction of New Technology

In the Forest Tower we have used CFT columns and oil dampers as a vibration control system, to achieve a high level of earthquake resistance. CFT columns are hybrid columns made by filling the inside of the steel-pipe columns with concrete. They combine the advantages of concrete, which is highly resistant to compression, and steel frames which are highly resistant to stretching. They are a component of the structure which produces a high level of earthquake resistance with outstanding deformation performance, because of their strong durability and high rigidity. The oil dampers absorb seismic energy to alleviate shaking as much as possible and ensure a high level of safety.
