What happened when a 30 story building suddenly shook?

I believe that when we hear that a 30-story building suddenly shakes, we will have a certain concern for the safety of the residents who live there. What happened to the 30-story building above? This has also triggered a lot of cognition among netizens.

However, according to news reports, it was suddenly discovered that it was the owner who demolished the load-bearing wall in the shop on the first floor, and chose to remove the load-bearing wall for decoration. But according to the on-site ** report, when the owner was interviewed. The owner said that there was a window on the wall that was demolished, and the owner admitted that he had demolished it, but it was not a load-bearing wall that was demolished.

For his part, he did the same when he was reporting here, he had the original drawings. For the other wall, it is a window, not a load-bearing wall, so we don't have a certain ability to justify this thing. Because there is no official name as to whether it was a window or a load-bearing wall in that place.

But for such a thing, it also brings a certain amount of trouble to a 30-story building, and for such a high height, many people come when the foundation is laid. Then the owner of the first floor will dig underneath, which will definitely not work for a building with more than 30 floors. For more than 30 floors to shake, such a thing will also bring a certain safety problem to the residents.

Such problems have also arisen in other places, leading to the tragedy of many people. <>

In fact, for the owner of the first floor, during the construction, you should get the drawings for a larger appraisal before going to the decoration, and you should also choose experienced professionals to carry out a series of construction. Avoid a series of unnecessary troubles caused by illegal construction. And for this, the more than 280 users in the high-rise building is also a psychological challenge.

After all, if it is implemented in the case of shaking the 30th floor, it will be a big loss for the construction of this house. <>

This is the news in Qingdao, which is actually because the owner of the first floor destroyed the architectural design of the original floor and carried out construction, so the 30-story building shook.

A 30-storey high-rise building in Qingdao suddenly shook, residents thought it had happened, and went downstairs to see that it was because: the shops on the first floor smashed the wall for decoration, and the construction party destroyed the original design of the floor, which caused the overall building to shake.

In fact, it is the load-bearing wall of the high-rise building that has been demolished, so the building will shake.

Since the 2008 Wenchuan Congress, people's vigilance has increased. I also know a lot about earthquake prevention, so I will run away from home as long as there is a shaking.

But recently there was an incident in which a 30-story building suddenly shook. This caused a sensation among the residents for a while, did it happen?

When the residents hurriedly ran downstairs from their homes, they found that the reason for the shaking of the floor was not ** at all, but because the load-bearing wall on the first floor was smashed. What's going on here?

No one can calm down when they encounter this kind of thing, and although the building only shook a little, everyone is still very worried. After all, it is 30 storeys high, and the building is home to more than 280 residents.

If the load-bearing wall is smashed, if something happens, who will be responsible? This will definitely have a huge impact on their lives, and no one will be able to live in peace of mind.

Therefore, someone went to the scene to check the situation and found that a large hole had indeed been smashed out of the first floor. **The owner of the load-bearing wall was also contacted, but this owner had another set of arguments. He said that the demolished part was not a load-bearing wall at all, it was originally just a window, but the owner has not shown the original drawings of the window so far.

How can such a cover-up be convincing?

In fact, about a week before this incident, some signs were shown in the place where it was smashed, and after the residents found out, they immediately reported it to the owner.

The property also posted a notice in time, but the construction team didn't see it, and they also changed their tricks. The shelves outside were intact and motionless, but the inside of the house had been smashed and I couldn't bear to look at it directly!

So the residents called the chengguan, but when the law enforcement officers arrived, the construction team had stopped the construction, but who can guarantee whether it will continue after that?

What is even more shocking is that as early as 2015, this wall was smashed once, and there was no reinforcement in it when it was restored. Now only large gray bricks are added, so that the foundation and frame of the entire building are not protected, which greatly reduces the stability of this wall. Naturally, there is no way to ensure safety, which buries a big hidden danger for residents.

In this regard, the urban management department has also dealt with it. In any case, the shops will not be allowed to carry out the so-called renovations, and they will be required to restore them to their original state.

The shaking of a 30-story building caused a sensation among residents, what caused the shaking?

It didn't happen**, because the shop on the first floor smashed the load-bearing wall during the renovation, and the property and residents couldn't control it, and now the Industrial and Commercial Bureau has intervened.

The sudden shaking of the high-rise building is not because of **, but because the renovation of the shop on the first floor smashed the load-bearing wall of the building. As early as a week ago, some residents discovered the behavior of smashing the wall of the store and put up a notice to warn them, but the other party not only did not heed the advice, but also insisted on smashing the wall from the inside.

No, residents ran down the upper floors, and only this building shook because the load-bearing wall was smashed open.

It's not that it happened, but the shops downstairs in the community smashed the load-bearing wall during the renovation, so the building was unstable, and the upstairs shook very badly.

No, the damage to a house is not a simple shake. The 30-storey building is affected by the wind and air currents at high altitude, and the building will swing within 10 centimeters from front to back, left and right, which is a reasonable shaking within the calculation range. If it is shaken out of range, it is dangerous, for example, if the load-bearing wall is broken.

The sudden shaking of the 30-story building is not a **, but the decoration of the shop smashed the load-bearing wall. Shops do not have the right to smash the load-bearing walls, which is related to the safety of residents, and I hope it will be solved as soon as possible.

The sudden shaking of the 30-storey building caused a sensation among the residents, and it was not **, and there was a problem with the foundation of the high-rise building.

The wind vibration effect causes tall buildings to shake.

The design of high-rise buildings carried out in accordance with the current technical regulations for concrete structures of high-rise buildings allows the building to produce a certain horizontal displacement under the action of strong winds, but the displacement must be within the specified limits.

High-rise buildings will form a wind vibration effect under the action of strong winds, excessive vibration acceleration will make people feel uncomfortable, this is the requirement of wind vibration comfort, the current design code has a limit on wind vibration acceleration, there are strict requirements for buildings with a height of more than 150 meters, and some people also suggest that the residential buildings with a height of about 100 meters (about 30 floors) should be strictly considered in the future.

The shaking of tall buildings is a kind of buffer against wind pressure.

He Youlin, project manager of Shenyang Baoneng of China Construction Third Bureau, said that it is normal for super high-rise buildings to shake back and forth, which is conducive to the safety of the building.

High-rise buildings "play Tai Chi", swing and "steady", which is also a buffer for wind pressure. Generally speaking, the higher the building, the greater the swing amplitude, and the tallest building in the Northeast under construction will swing by more than half a meter.

Isn't it hard for you to hold an iron rod? That's right! Because iron is strong.

What about wire? Isn't the wire very soft? That's right! Because iron is also flexible.

So how do you balance sturdiness and flexibility? It's not that the flexibility of the iron bar is not shown, but it is very slight, and when the length is very short, its sturdiness predominates. And once the length is enhanced, flexibility dominates.

To answer your question, the above does not refer only to iron, but to any solid, but to any solid, but in a different proportion of its solidity and flexibility. Compare a building to an iron rod, which is short and strong on the first floor; On the 16th floor, the role of length gradually came into play, and flexibility began to come in handy, and at this time, the "iron rod" began to change to "iron wire".

In terms of design, we allow the top floor of high-rise buildings to have a small displacement under the action of lateral stress, which is very small and cannot be felt by people. This is designed to reduce damage to the building caused by high winds or other stresses, which is understandable as part of the energy brought by the wind is consumed in the work of the building's displacement.

If the height of the building does not shake, it is easy to fall down, just like taking a big tree as an analogy, the tree is high and swaying back and forth, this is the truth.

1. What is the reason for the shaking of high-rise buildings?

If the high-rise building occasionally shakes, it may be a typhoon, or the shaking caused by **, but if the long-term shaking, it can be caused by the construction site construction around the building, mining, etc., if there is no such situation around the building, it is necessary to consider whether there is a safety problem in the building, it is best to find someone to come to investigate.

2. Is it dangerous for the house to shake slightly?

1. There is no danger of a slight shaking of the general house, because when there is a strong wind blowing through, the wind around the high-rise building has a pulsating effect, which will form a whirlpool, so that the wind and the building will have friction, if the wind is stronger, the friction will be greater.

2. The higher the floor, the greater the degree of shaking, if in the normal wind pressure state, 10 meters from the ground height, the wind speed is 5 meters per second, then 100 meters in the air, the wind speed can reach 15 meters per second, if it is as high as 500-600 meters, then the wind speed will be strengthened, but it will not cause damage.

3. Precautions for living in buildings

1. If you live on a relatively high floor, you should pay attention to observe the surrounding environment, find the staircase exit, avoid encountering natural disasters, and escape in time.

2. For the older house, it is necessary to pay attention to check whether the functional facilities in various aspects are aging, if there is aging, there will be a certain danger, and it is necessary to maintain it in a timely manner, especially in terms of load-bearing walls, if the load-bearing capacity becomes worse, it should be repaired in time, so as to ensure safety.

3. If the weather in the place where you live is relatively bad and natural disasters often occur, you must pay attention to the quality of the house, and the profession can resist natural disasters.

The shaking of tall buildings is a kind of buffer against wind pressure. It is normal for super high-rise buildings to shake back and forth, which is conducive to the safety of the building, and most of the high-rise buildings are steel structures, which will play a buffering role in lateral pressure.

How much does a high-rise swing have?

It needs to be considered in combination with the local climate and the structure of the building. However, the relevant treaty stipulates that the height of the building shall be less than 150 m and the swing limit shall be between 1,550 and 1,1000. If the building height is less than 250m, the swing limit cannot exceed 1 500.

Slow stopping. What causes high-rise swings?

1. In the process of building high-rise buildings, the foundation is to meet certain strength requirements, and the connection method is relatively unique, so that the high-rise buildings will be elastic, so that the building has a certain safety performance, and can offset the impact of wind through its own shaking, and reduce the pressure exerted.

2. If the high-rise building only shakes occasionally, it is very likely to be caused by the influence of wind. If it is shaking for a long time, it depends on whether there are large vehicles passing by nearby, or if there is a large construction. However, if the above situation does not exist, and there is a long-term shaking, it means that it is a problem with the building itself, and you need to contact a professional.

Why do high-rise buildings need to shake?

1. The shaking of high-rise buildings is to reduce the impact of wind pressure on the building itself, which has a greater disturbance guarantee for the safety of the stairs. In addition, most of the high-rise buildings are made of steel structures, and the shaking can pile up lateral pressure and bring a certain cushioning function.

2. If the high-rise building does not shake, or the shaking amplitude is relatively large, it is more dangerous. Generally speaking, high-rise buildings need to be able to resist wind speeds of up to 40 meters per second in order to be sufficiently safe. Therefore, in the construction process, special attention should be paid to the materials and designs used.

The shaking of tall buildings is a kind of buffer against wind pressure. It is normal for super high-rise buildings to shake back and forth, which is conducive to the safety of the building, and most of the high-rise buildings are steel structures, and the cluster will play a buffering role in the lateral pressure. For example, the top of the concrete TV tower will shake by 1 meter under the action of general wind, and the key point in the structural design of high-rise buildings is the lateral force.

High-rise buildings are high-rise buildings, and traditionally, buildings with more than 9 floors and elevators can be called high-rise buildings. However, in modern society, due to the increasing number of high-rise buildings and the higher and higher heights, a new definition has been added to high-rise buildings, generally more than 18 floors are called high-rise buildings, and more than 100 meters or 30 floors can be called super high-rise buildings or skyscrapers. In Chinese mainland, building codes stipulate that buildings with a height of more than 100 meters are super high-rise buildings; In Japan and France, more than 60 meters are super high-rise buildings; In the United States, buildings over 500 feet (152 meters) are generally considered skyscrapers.

According to the new standard of the World Council of Supertall Buildings, more than 300 meters is a super high-rise building.
