Seg Building, a landmark building in Shenzhen, is shaking again. What is the reason?

On May 18, the slight shaking phenomenon of Shenzhen SEG Building boarded the hot search in Weibo. Many netizens are speculating about this matter and want to know why Dasha is shaking. In this regard, Shenzhen officials also stood up and responded at the first time. So what is the reason for the building shaking?

First, after the wind direction and environment happen, the first reason that people think of is whether there is an earthquake. But then, according to the response of the relevant authorities in Shenzhen in Weibo, we can know that Shenzhen officials clearly stated that no signs of earthquake were found through the data of the monitoring station and observation of the underground wall.

In addition to the cause of the earthquake, some related professionals have come forward to say that it may be due to the influence of the wind, because in a specific wind direction environment, buildings and wind may produce the phenomenon of * * * vibration, which will lead to slight shaking of buildings, and it is also true that the wind around Shenzhen SEG Building was relatively strong that day.

Second, environmental factors In fact, there was a similar wave vibration phenomenon in Humen Bridge in Guangdong last year. From that video, it can be clearly seen that the bridge has obvious shaking. But the final result proves that it is not the quality or structure of the bridge that has problems, but the bridge vortex vibration phenomenon.

According to the response of relevant authorities, we can know that the structure, so-called tilt rate and shaking frequency of SEG Building are up to standard. Therefore, it is more likely that the building is shaking because of the coupling effect of environmental factors and various factors.

Third, the coupling effect of various factors After various tests, investigations and evaluations by experts, it is found that the reason for the building shaking is the specific wind environment, and at the same time, because there is a subway passing under the building, the temperature difference between those two days is relatively large, which will have an impact on the steel structure. The existence of various factors led to the sloshing we saw.
