Resilience Technology Example

Changing the way cities are built (changed and protected)

The functions required of architecture change with the times. Architecture needs to be flexible enough to respond to changes in use and renovations, and easy to maintain.

Technology to enhance building resilience

Existing Technology

-Improved basic performance
By ensuring continued use after an earthquake and safety against earthquakes that exceed assumptions, we aim to use buildings sustainably and extend their lifespan.

・ seismic control
In order to control damage to the structure during an earthquake, vibration control devices are used to improve earthquake resistance. This also leads to improved basic performance and a longer lifespan.

・Seismic isolation structure
The swaying of the superstructure can be reduced, allowing for greater planning freedom.

・Seismic isolation retrofit
Seismic isolation devices are installed under the foundations of existing buildings to provide seismic isolation. This is used when it is not desirable to reinforce the main structure above ground.

・Skeleton infill
By clearly separating the skeleton and the infill,
It is easy to change the layout.

・Mega Frame
By enlarging and consolidating the main structure, the flexibility of areas other than the main structure will be improved.
The infill range of skeleton infill includes detachable columns and beams.

・Dry floor (PC floorboard, CLT floor, etc.)
By enlarging and consolidating the main structure, the flexibility of areas other than the main structure will be improved.
The infill range of skeleton infill includes detachable columns and beams.

Acceleration sensor
The extent of damage to buildings after an earthquake is determined based on the vibration monitoring results of buildings obtained by acceleration sensors installed in the building.

Technologies expected to be used in the future

・Wooden structure
Because it is lightweight, it is easy to transport and there is a great deal of freedom in renovating it.
However, there are issues with its fire resistance, and there are limitations on where it can be used.

Advanced technology
3D Printer:
Fabricating beams and other parts on-site allows for greater freedom in shape and eliminates issues with transporting them in and out.
Although on a small scale, 3D printers that use mortar and steel are still being announced.
