Sika Strengthen Tokyo’s new Azabudai Hills Development

Azabudai Hills is a new development in the Minato district in the heart of Tokyo. Over 30 years in the making, the project is an expression of future city trends. Life and work, education and the arts, hospitality and fine dining, shopping and outdoor recreation, all blended in a redevelopment project that turned a hilly, haphazardly spread neighborhood into Tokyo’s premier new business and tourist attraction. This mixed-use complex will be able to accommodate some 20,000 employees, 3,500 residents, and 30 million visitors annually.

Tall buildings need to avoid swaying in the wind and given the high likelihood of earthquakes in Tokyo, the most stringent standards apply. In addition to high stiffness requirements, provided by filling steel tubes with high-strength concrete, viscous dampers, oil dampers, and Active Mass Damper devices are used. But the approximately 330-meter Azabudai Hills Mori JP Tower does not just protect its own residents: 3,600 additional people can find shelter from earthquakes inside the building and storage space for disaster relief supplies has also been included. "With Sika admixtures, concrete is stronger, allowing stiffer concrete-filled tubes that meet the strictest specifications for earthquake resilience." said Kazumasa Okabe, General Manager of Mori Building’s Structural Design Unit
