Prepare for Typhoons
As measures against strong winds including typhoons, Abeno Harukas uses the building’s shape to reduce vibration and has equipment that utilizes the characteristics of a pendulum to provide comfortable livability.

The building’s shape, which is set back in three vertical stages, helps to control vibration caused by the west wind, the prevailing wind direction in this region. This is because the building’s shape reduces the effect of the Karman vortex released toward the back of the building to mitigate the resonance effect.
Experimental investigation of aerodynamic forces and wind pressures acting on tall buildings with various unconventional configurations,JWEIA.
*If the coefficient is smaller, a lower wind load may be expected.
A pendulum-type damper called ATMD is installed on the building’s top section. This damper minimizes vibration by aligning with the building and keeping the building quiet even during strong winds. |
