Earthquake Resistant

Earthquake Resistant

The building is built on the joint of two ridges, giving it a super firm foundation. Motoazabu Hills is one of the few buildings in the city center with a base isolation structure.

The architecture employs two types of base isolation technologies to maximize their effectiveness against the shock of earthquakes – the first is the lead rubber isolator (LRI) in which a lead plug is embedded at the core of layers of natural rubber, combining the rubber’s ability to flex with the damping effect of the lead to reduce the force of earthquake shock and vibration. The second is use of high-purity layered natural rubber, in which the composition of the rubber has been adjusted to maximize tensile strength against up and down movement in the base isolation equipment that decouples the building from earthquake movement in the ground. This rubber was developed specifically for use in constructing earthquake-resistant high-rise buildings and substantially increases the earthquake damage resistance of the structures in which it is used.
