Active floor vibration control for high-rise buildings
Global skylines are evolving fast - buildings over 656 feet have doubled since 2017 - and another 500+ are on the rise now.
The CTBUH 2025 Forecast demonstrates that today’s high-rise market is more ambitious than ever, pushing structures higher, lighter and more open-plan. But as towers get taller and structures get lighter, achieving precise floor vibration control without adding weight, carbon or construction cost is harder than ever. CALMFLOOR is redefining floor vibration control for the next generation of sustainable high-rise design.
Taller buildings amplify the challenge of floor vibration making precise control critical
High-rise structures push engineering boundaries. With lighter, more flexible frames, expansive open-plan floors and minimal columns, today’s towers maximise space and skyline presence – yet these same design features increase exposure to low-frequency floor vibration.
Wind-induced sway, mechanical systems, foot traffic and lifts generate floor vibration that travels through floors and structural frames. In commercial towers, floor vibration impacts productivity, occupant comfort and regulatory compliance. In residential skyscrapers, it undermines the living experience and drives up long-term maintenance costs.
Costly traditional solutions – adding extra concrete or heavy steel reinforcement – attempt to tackle floor vibration by brute force. This adds excess weight, increases embodied carbon and inflates construction costs – all while severely restricting architectural freedom.
Ideal for:
Commercial office towers
Residential skyscrapers and mixed-use tall buildings
Tall buildings with open-plan floors and minimal columns
Structures using lightweight steel or composite frames
Projects facing strict compliance and comfort performance criteria
Sustainable developments targeting net-zero and lower embodied carbon
CALMFLOOR delivers precise floor vibration control, maximising high-rise potential
CALMFLOOR active mass damper (AMD) technology redefines how floor vibration is managed in tall, high-rise buildings. Each compact CALMFLOOR AMD weighs just 67kg (148lbs) and is mounts exactly where needed: within beam webs, ceiling voids or directly on the floor slab.
Simulation-led placement pinpoints floor vibration hotspots, eliminating unnecessary structural overdesign. By actively managing floor vibration at source, CALMFLOOR reduces the need for excessive steel and concrete – cutting floor steel by up to 75% and lowering total floor weight by as much as 25% in typical high-rise floorplates. This space-saving approach means shallower floors, reclaiming vertical space that can unlock additional lettable floors within the same building height.
Unlike conventional mass-based damping or structural stiffening, CALMFLOOR delivers superior floor vibration control with lower embodied carbon and no added dead weight, allowing you to achieve Net Zero sustainability goals.
Safeguard high-rise occupant productivity, comfort and compliance on every level
In high-rise office towers, excessive floor vibration impairs occupant concentration and comfort, particularly on long-span, flexible floors. For commercial tenants, this degrades workspace value and risks non-compliance with industry floor vibration standards.
In residential skyscrapers, perceptible floor vibration unsettles residents and drives complaint rates. CALMFLOOR ensures floors perform to optimal floor vibration standards, protecting productivity, comfort and regulatory compliance, from lobby to top floor.
Why CALMFLOOR?
Simulation-led placement for precise, data-driven control
Portable system: relocate units as space use evolves
Facilitates compliance with comfort, safety and floor vibration standards
Live building performance data through CALMCONNECT smart portal
Lower embodied carbon, supports net-zero design goals
Proven floor vibration results, adaptable to any high-rise design
CALMFLOOR AMDs are portable, compact and installed in hours. Our simulation service models your building’s modal properties to define the exact unit quantity and optimal placement. The portable, lightweight units can be redeployed as layouts change or floor vibration risks evolve.
This makes CALMFLOOR the superior floor vibration solution for both new towers and retrofit upgrades to existing high-rise structures, delivering lighter floors, less steel usage and extra space without structural compromise.
