The SEG Building, a landmark building in Shenzhen, is shaking again. What is the cause?
On May 18, the phenomenon of slight shaking in the SEG Building in Shenzhen was posted on Weibo hot search. Many netizens kept speculating about this matter and were wondering why Dasha exists. The Shenzhen government immediately responded to the shaking phenomenon. So what exactly causes this building to shake? 1. Wind direction environment
After the incident happened, the first reason everyone thought of was whether there was an earthquake. However, according to the response from relevant Shenzhen authorities on Weibo, it can be known that Shenzhen officials made it clear that no signs of earthquakes were found through data from monitoring stations and observations of ground and walls.
In addition to ruling out the cause of the earthquake, some relevant professionals also stood up and said that it may be due to the influence of wind, because in a specific wind direction environment, the building and the wind may produce a * The phenomenon of ** vibration will cause the building to shake slightly, and it is true that the wind around Shenzhen SEG Building was relatively strong that day.
2. Environmental factors
In fact, last year, a similar wave-like vibration phenomenon occurred in the Humen Bridge in Guangdong. It can indeed be clearly seen from the video I saw that the bridge was shaking significantly. But in the end, it turned out that it was not the quality or structure of the bridge that had problems, but the bridge's vortex vibration.
This time the SEG Building shook. According to the response from the relevant authorities, it can be known that the building's structure, as well as its so-called tilt rate, shaking frequency, etc., are in compliance with regulatory standards. Therefore, one of the more likely reasons is that environmental factors and the coupling effect of various factors cause the building to shake. 3. Coupling effects of multiple factors
After various tests and investigations and evaluations by experts, it was found that the reason for the shaking of the building was due to a specific wind environment and also because of the presence of rocks below the building. The passing of the subway, coupled with the large temperature difference between those two days, will have an impact on the steel structure. The existence of various factors leads to the shaking we see.
