Skyscrapers Sway in High Winds—Engineers Just Found a New Way to Stop Them
Summary
Researchers have found a new way to design tall buildings that uses the building's own weight to reduce movement from strong winds and earthquakes. This method can cut the building’s sway by up to 70 percent and reduce stress on its structure by more than half, potentially making skyscrapers safer and more efficient.Key Facts
- The new design uses the building’s own mass rather than adding traditional heavy dampers to control shaking.
- It reduced wind-induced movement by up to 70 percent compared to conventional skyscrapers.
- Structural loads on the building’s foundation and frame were cut by over 50 percent.
- The design also decreased earthquake motion by an average of 42 percent in tests.
- This approach could lower construction costs and materials needed, saving carbon emissions.
- It relies on common building technologies, not complex new machines.
- The team plans to apply this design in a real building project next.
- The study was published in the scientific journal Nature Communications.
