Tell me about the one on the 28th floor.

Don't worry, in fact, the building is also a "flexible" structure with certain deformation ability, which will shake. As long as the strength is strong enough, such as strong wind or high earthquake intensity, it is not difficult to shake the building!

Moreover, these buildings also have natural frequencies. If the flutter caused by wind disturbance or earthquake wave comes, the frequency of building shaking is close to or several times the natural frequency of the building, and it will also cause * * * vibration!

Many modern high-rise buildings are over 100 floors.

How to prevent these buildings from shaking too much in the strong wind has become a necessary job, otherwise, when the strong wind comes, the staff who work in them will be dizzy, so it is estimated that the buildings will not be sold, and even the rent will not be rented!

In fact, earthquake resistance can also resist the shaking of buildings under strong winds. In addition to blowing holes in the design of the building, we should try to avoid excessive wind resistance or serious impact on the building under the wind at a special angle. Generally, damping devices will be installed at the connection points of buildings, so that the damping devices can absorb the shaking of buildings and make these energies disappear invisibly, or at least prevent the shaking of buildings from intensifying. Damping is working!
