Resonant vibration in buildings refers to the phenomenon where the house resonates with the surrounding objects at the same vibration frequency. When the objects vibrate, the house follows suit. From a professional standpoint, resonance is the situation where a physical system vibrates with a larger amplitude at a specific frequency compared to other frequencies; these specific frequencies are known as resonance frequencies.

One,What are some house resonance or vibration issues in daily life?

1) Properties near subway/expressway.

2) Industrial factory building, machinery vibration causing building shake

3) Explosion occurred, causing the house to vibrate.

4) Earthquakes and other natural disasters.

House vibration; resonance between house and machinery; earthquake-induced house shaking

What are the hazards of building resonance?

The likelihood of resonance in buildings is very low, but when it occurs, the consequences can be severe. Even new buildings can collapse instantly when resonating with surrounding elements. Of course, many vibrations in daily life won't cause immediate building collapse, but they can affect the safe use of the building, such as long-term vibrations leading to cracks, settlement issues, and more.

Resonance Detection for Buildings？

Using professional vibration detection equipment, we measure the vibration frequencies of both the house and surrounding objects, analyze their frequencies, and assess whether they impact the house and the extent of that impact.

How can the issue be resolved or mitigated if an impact on house safety is detected?

Common solutions include:

1) For industrial factory machines, the working speed of the machine can be adjusted, and the frequency can be altered.

2) Additionally, shelves can be added between buildings and objects to reduce vibration.

3) If explosion or earthquake has already caused damage to the building, it is recommended to undergo reinforcement design.
