Shenzhen Huaqiang North Seg Building was suspected of tilting and shaking, and a large number of people were evacuated. What could be the reason?

Shenzhen Huaqiang North Seg Building is suspected of tilting and shaking, and even dug up a "prediction" paper on the Internet to question the quality of Seg Building. There are already relevant official "identification" documents. The document was issued by the duty room of the Emergency Management Department of Guangdong Province, and made public the conclusions made by scientific research institutions and experts on this incident.

"According to the judgment of provincial and municipal experts, it is preliminarily considered that: First, Shenzhen SEG Building trembles up and down, not from side to side; Secondly, the tremor is caused by the coupling of many factors, mainly the influence of wind, as well as the influence of subway operation (two subways pass downstairs) and temperature (the temperature has risen in the past two days, and the temperature difference has reached 8 degrees, which has a great impact on steel structures); Thirdly, after on-site investigation and expert consultation, the main structure of SEG Building is safe, the internal structure is firm and all kinds of ancillary facilities are in good condition. "

The suspected tilting and shaking incident of Shenzhen Huaqiang North Seg Building caused a huge storm on the Internet, and a related "prediction" paper more than 20 years ago was dug up.

I. "Prediction" of the suspected tilting and shaking event of Shenzhen Huaqiang North Seg Building Following the shaking event of Shenzhen Huaqiang North Seg Building, a master's thesis of Huazhong University of Science and Technology was once again dug up by public netizens 20 years ago. The content of this paper is the analysis and evaluation of Huaqiang North Seg Building.

The title of this master's thesis on Shenzhen Huaqiang North Seg Building Project is "Comment on Shenzhen Seg Plaza Construction Project". This is a master's degree thesis by Jin Dianqi under the guidance of Professor Zhang Zigang. Now this classmate Jin Dianqi has become an executive and senior engineer of a company. But he didn't accept the reporter's interview, after all, the paper at that time was not rigorous.

In this regard, Zhang Zigang, a professor at Huazhong University of Science and Technology, said in an interview that although some viewpoints were put forward in the paper, it does not mean that it is scientific. Because it is a management school, involving a wide range, not an architecture major, so the requirements for the thesis are relatively loose.

Secondly, the analysis mentioned in the article "Shenzhen Seg Square Construction Project Evaluation" is not rigorous. It is mentioned in the article that after the construction drawing of Shenzhen Huaqiang North Seg Building came out, it caused the design of Gai Lou, so it was revised many times during the design process, and a complete design drawing could not be provided at the moment.

In fact, the construction method of designing while constructing is also common in construction management, and it is not a problem. If you know anything about architecture, you should know that there are two ways of general contracting: general contracting and general contracting.

The project under "general contracting" mode needs complete design drawings to ensure. The project of "main pipeline" mode does not need complete design drawings to ensure that it can be designed and constructed at the same time.

However, this paper only mentions that the contracting mode is general contracting, and does not explain whether it is "general manager" mode or "general contractor" mode. So this is the place where the paper is not rigorous. Because if it is the "supervisor" mode, there is no problem in designing while constructing.

Third, the expert appraisal results further overturned the doubts about the construction project of Shenzhen Seg Square. According to experts' preliminary appraisal, the tremor of SEG Building is not shaking from side to side, but shaking up and down. Normal causes are related to natural factors, mainly the influence of wind and temperature.

In Shenzhen, the subway under the Huaqiang North Seg Building will also cause some tremors when passing by. Coupled with the temperature and natural conditions, the building trembled up and down.

Fourth, concluding facts is the only criterion for testing truth. So before the result of things really happens, everything is just an inference.
