seismic isolation; earthquake isolation; base isolation
A structural engineering technique that isolates a building from ground motion during an earthquake, reducing the shaking transmitted to the structure.
このビルは免震構造だ。
This building has seismic isolation.
免震装置が地震の揺れを大幅に減らした。
The seismic isolation system greatly reduced the earthquake shaking.
最近の高層マンションには、免震技術が取り入れられていることが多い。
Many recent high-rise apartment buildings incorporate seismic isolation technology.
Compound of 免 (exempt, avoid) + 震 (tremor, earthquake). Japan is a world leader in seismic isolation technology due to its high earthquake risk.
COMMON COLLOCATIONS:
- 免震構造: seismic isolation structure
- 免震装置: seismic isolation device
- 免震技術: seismic isolation technology
- 免震ゴム: seismic isolation rubber bearing
SIMILAR WORDS:
- 耐震: earthquake-resistant — makes the building strong enough to withstand shaking, rather than isolating it from the shaking
- 制震: vibration control/damping — uses devices to absorb and reduce vibrations within the structure
NOTE:
In real estate listings, 免震 is considered a premium feature and often highlighted as a selling point for apartments and condominiums.
