people still remember the "9.11" terrorist attacks. The twin towers of the world trade center in New York, which the United States is proud of, completely collapsed in less than two hours. Many people still don't understand why a building made of steel and iron can't stand a collision? When the plane hit the upper part of the building, why did it cause the whole building to collapse? Why does the building collapse vertically instead of toppling over
it may take a long time to investigate the cause and process of the collapse of the building, and it may even become a mystery forever However, through the analysis of relevant data and images, the experts still got a preliminary analysis result of the collapse of the building. Although the plane collision did cause some damage to the building, the subsequent fire was the direct cause of the collapse of the building< The World Trade Center building, built in 1973, was the tallest building in the world. It is about 411 meters high and is a steel structure system with outer frame and inner wall. The United States built this giant with high-strength building steel and high-level structural design technology. During the construction period, more than 200000 tons of steel and 320000 cubic meters of concrete were used
the steel columns of the steel structure of the world trade center are very dense. Both the building materials and the structural design are very advanced in the world at that time. The building not only survived nearly 30 years of wind and rain, but also failed to topple immediately e to the huge impact of the plane. The take-off weight of the Boeing 757 and the Boeing 767 that hit the building is 04 tons and 56 tons respectively. Their flight speed is about 1000 kilometers per hour. You can imagine how powerful the impact of these two airliners on the building is. But according to survivors, although the impact caused the building to shake nearly 1 meter, there was no serious collapse inside or outside. This is the key to the escape of a large number of staff in the building< However, e to the unavoidable inherent defects of super high-rise buildings, they can not avoid the fate of complete destruction. Super high-rise buildings must be constructed with steel, and steel has a fatal disadvantage, that is, it softens in high temperature and loses its original strength. In order to avoid the disaster caused by this, the building steel is coated with fireproof coating and other protective materials. However, such a low level of protection can cope with ordinary small disasters and small fires, but it is impossible to cope with such a fierce fire
the heavy fire for a long time has softened the steel of the floors hit by the aircraft, and the weight of the upper floor is about thousands to tens of thousands of tons, which will naturally fall down, like a huge hammer, hitting the lower floor. The impact on the lower floor structure is far greater than its original static gravity, and the lower floor structure is naturally unbearable, So, layers of them collapse vertically
the first aircraft to hit the building is Boeing 757, which can carry 35 tons of fuel; The second aircraft is Boeing 767, which can carry 51 tons of fuel. Shortly after take-off, the fuel carried by the two planes almost did not waste on the building, causing a raging fire. In addition, the location of the second impact was low and the upper pressure was high, so it is not difficult to understand why the building that was hit later collapsed first< Some people may wonder why the Empire State Building in New York did not collapse when an American military plane hit it in 1943, and the Empire State building was built 40 years earlier than the world trade center. This is partly because the plane is smaller and has less gasoline, which did not cause a fire. On the other hand, the fire performance of the Empire State building is better than that of the world trade center. The Empire State building is a steel reinforced concrete structure with a layer of concrete on the outside of the steel. Its fireproof performance is better than that of the World Trade Center applying fireproof coating on the surface of the steel structure
in fact, many international architectural experts have long strongly opposed the construction of super high-rise buildings. They especially emphasize that the safety of super high-rise buildings is extremely poor. In case of natural disasters such as fire, wind, earthquake or man-made damage and quality accidents, the consequences will be unimaginable. The collapse of the world trade center in New York may mark the end of the skyscraper era.
it is reported that the collapse of the building was not caused by the direct collision of the aircraft, but by the huge heat released by the fire caused by the full load of aviation kerosene pouring into the building, which softened the steel skeleton supporting the building and eventually led to the collapse of the World Trade Center building under its own gravity. However, a group of architects believe that the fire alone can not make the building collapse
according to the loose change, it is pointed out that none of the reinforced buildings in the history of architecture collapsed e to burning, and the collapse speed of the buildings is similar to the demolition and disintegration of buildings with explosives. At that time, the mayor of New York quickly transported the remains of the world trade organization abroad as waste. Whether there were traces of explosives in them could not be identified. As for the high temperature of the fuel leaked after the aircraft hit the building, it is not enough to dissolve the steel bars and even affect the structure of the whole building. Morgan Reynolds, former chief economist of the U.S. labor office and a participant in the September 11 truth movement, agreed that the two airliners could not bring down the world trade center
some opponents of conspiracy theory believe that the impact of the two Boeing 767 aircraft damaged the twin tower support columns and steel floor brackets, causing the columns around the twin towers to collapse inward and the steel floor to be pulled down[ 2]
No.7 building collapsed
no aircraft impact or terrorist attack occurred on No.7 building, but soon after the collapse of No.1 and No.2 buildings, No.7 building also collapsed. According to loose change, there were some flashes before the collapse of building 7, so it was believed that the flash was caused by the explosion of explosives in the building, which led to the collapse of building 7. Although it has been pointed out that building 7 collapsed because of the strong impact of the aircraft, it can not explain why only building 7 collapsed while other buildings did not.
there are also American ones, which are gone now..
On February 26, 1993, at noon, the busiest time of the day, there were 100000 people working and visiting in the world trade center. Office people are busy and visitors are in high spirits. No one expected that a great disaster was implied in the singing and dancing
at 12:18, everyone in the World Trade Center heard a loud bang, and the building began to shake. People still don't understand what's going on, and it's dark all around...
screams of panic resound through the sky! Many people were trapped in the elevator and cried for help in despair. Some people were ready to walk down the 400 meter high building. However, the thick smoke made them unable to move forward, so they turned to the top platform and waited for help
the explosion took place in the parking lot on the second floor under the building. A 60 meter long and 30 meter wide pit was blown out, and the whole basement was penetrated. The car was destroyed, concrete fragments were flying everywhere, the huge shock wave cut off the power system of the building, the telephone was cut off, the elevator was stopped, many fires broke out in the building, and the thick smoke came up to the top floor of more than 400 meters
