According to US media reports, at around 1:30 am on June 24, a 12-story apartment in Miami, Florida, USA partially collapsed (136 units, about 55 collapsed). Three people have been confirmed to be dead, 99 people have lost contact, and rescue is still ongoing.
Local authorities said: The entire search and rescue work may last for several days or even a week, and it is not certain whether another part of the building will collapse, so the situation is very urgent now. In addition, most of the residents in the building are foreigners .
At present, the reason for the collapse of the building has not been announced, but according to the mayor of the city, it is difficult for him to believe that the building will collapse by itself. In addition, according to a researcher at Miami International University, the building was built in the 1980s, and after 1990, relevant departments discovered that the building was sinking at a rate of 2 mm per year. But it is still hard to say whether this is the main cause of the accident.
To be honest, when I saw this news, I immediately remembered the collapse of a 7-story self-built building in Chenzhou, Hunan two days ago. Fortunately, most of the residents in the building went out at that time, so no more serious casualties were caused.
However, this apartment in the United States collapsed. First of all, the residents should be sleeping in the early morning of the incident. Secondly, the 12-story building collapsed in a total of 55 units. According to media reports, 99 people have lost contact, and the consequences of the accident can be imagined.
Therefore, I want to write an article to introduce some major construction accidents that have occurred in the history of various countries to show the warning and use practical cases to illustrate that the construction process of high-rise buildings is not a little bit of fun, after all, life is at stake.
The New World Hotel in Singapore collapsed, 33 people died and 17 people were injured
On March 15, 1986, the New World Hotel in Singapore, at around 10 o'clock in the morning, a staff member reported that concrete fragments fell in the underground parking lot. Then the manager went to check and found that it was a crack in a column, but maintenance personnel were already strengthening it, so everyone worked as usual, but only an hour later, the collapse began, and the entire building was split in 60 seconds, 33 people died and 17 people were injured.
Cause of the accident: It turned out that at the beginning of the construction of this building, an unqualified building party was hired, which resulted in the unreasonable structural design of the building and the materials used during construction did not meet the standards. After completion, the use of the corresponding floor was privately changed, put it in a 22-ton bank vault, and used 50-ton ceramic tiles to decorate the exterior surface of the building. Moreover, in the years before the building collapsed, there were many dangerous signs, such as cracks in the walls and columns, desolation in the ceiling, etc., but none of them were taken seriously.
The Royal Plaza Hotel in Thailand collapsed, 137 people died, 227 injured
On August 13, 1993, the sixth floor of the Royal Plaza Hotel in Thailand, which was hosting several large-scale conferences, collapsed and countless deaths. Afterwards, it was found that the reason for the collapse was that the building had been illegally built three floors at that time, but the water storage device was placed on the top floor (the water storage device was to ensure the normal water supply of the building). Over time, the building eventually collapsed.
Sanfeng Department Store in South Korea collapsed, 502 people died and 937 people were injured
June 29, 1995, on the morning of that day, staff inside the building suddenly found cracks in the pillars in the building, but it was not until 2 pm that Sanfeng Group asked the engineers to go over for maintenance, and the engineers suggested that business be closed immediately. But the management of Sanfeng Group rejected the proposal. They did not want to lose the turnover of the day in vain. It was already afternoon anyway, and it had been half a day since the crack was discovered, so there was nothing big. Let's continue to open.
Disaster occurred, which happened around 5 pm. The entire building completely collapsed into a ruin in less than 20 seconds, and 502 people died.
After investigation, it was found that the building should have been a fourth floor for office work, but later Sanfeng Group decided to change it to commercial use, so it changed the building party and built an additional floor. The original construction design was greatly changed (this has laid a safety hazard for the accident). Later, in order to increase income, it decided to change the fifth floor to a traditional Korean restaurant (because it needs to be installed, it is much heavier than an ordinary restaurant), and thirty tons of air-conditioning equipment were placed on the roof.
So the entire building was under such a heavy load, and lasted for 6 years and finally collapsed. It can be seen that the fundamental cause of the entire accident was caused by the unreasonable architectural design in the future, but the direct cause was man-made. There was a chance to avoid casualties, but he ignored his life for the sake of benefit.
The Gena Building in Bangladesh collapsed, 1127 people died, 2437 injured
On April 24, 2013, an eight-story industrial building collapsed in Bangladesh capital Dhaka . At the time of the accident, 3122 workers were working in the factory. This is why the accident was like a major casualty. According to the subsequent investigation, the reason for the collapse of this building was similar to the Sanfeng Building in South Korea.
it originally was used for commercial purposes at first, but later the owner of the building changed it into an industrial building without authorization, and built four floors, turning the original four-story building into eight floors (the building materials do not meet national standards). Later, he moved four heavy-duty diesel generators to the top floor. So when it was originally a dangerous building, coupled with the vibration of heavy equipment, the tragedy finally led to this tragedy.
Summary
Through the above major building accident cases, we found that many buildings collapsed often have their own unreasonable design or the building materials are not compliant, and later human factors, such as privately building, destructive decoration, installation of heavy equipment, neglecting building abnormalities, etc. By the way, some people ignore the lives of others for the sake of their interests.
Society is developing, and more and more high-rise buildings are built, so more attention should be paid to the safety of buildings. After all, as a building with a high user density, the consequences will be unimaginable once an accident occurs.
