Concept

Enhancing safety and functionality of the buildings and creating comfortable living environment in the earthquake prone country like Japan. That is the main concept of structural control and base isolation structures.
Kajima has taken the initiative in the industry by conducting research in structural control and base isolation and putting its technologies to practical use.
We are still a leading company that continues to take the lead in the world of structural control and base isolation technologies.
As shown by our long track record, we provide customers with the optimal building safety that meets their needs.

Overview of Technologies to Protect Buildings from Various Vibrations

Principal Technologies

Seismic Structural Control System

1989 Completing the word's first actively structural control building.
Experience in completing more than 200 projects, which marks 25% of the domestic share.
Seismic control system using vibration energy absorbers installed in a building restricts the movement due to earthquakes or strong winds to protect facilities, habitability, and to prevent damage to the building.

Base Isolation System

1986 Completing the word's first Earthquake protection and vibration isolation building.
Experience in completing more than 300 projects which marks 10% of the domestic share.
Base isolation is a construction method for protecting buildings, in which the building and ground are separated by an isolation system to limit the transmission of vibrations through the building.
