Sumitomo Rubber's vibration control technology, “GRAST”, uses high-damping rubber that converts vibration into thermal energy to absorb it, effectively reducing a wide range of vibrations – from small vibration like wind – induced sway to large-scale shaking caused by earthquake.
Sumitomo Rubber's vibration control technology, “GRAST”, reduces a wide range of vibrations, from minor swaying caused by wind to major earthquakes.
It is utilized in various structures such as bridges and super high-rise buildings.
Sumitomo Rubber's fundamental approach to vibration control technology
Vibration control is one of the technologies used to protect buildings from earthquakes and other forces.
Sumitomo Rubber's vibration control technology, “GRAST”, utilizes high-damping rubber developed through technologies cultivated over many years of research and development in racing tires such as Dunlop tires.
“GRAST” supports the realization of high-performance buildings even under various constraints such as site conditions and cost.

Sumitomo Rubber's vibration control technology effectively mitigate the sway of high-rise buildings caused by long-period ground motions through the use of high-damping rubber. It also delivers excellent damping performance against micro-vibrations that conventional seismic-resistant structures find difficult to address, thereby enhancing both building safety and the comfort and peace of mind of occupants.
