Now that the house is being built higher and higher, but it will not fall, what is the principle?

Tapering. In general, the higher the altitude of the same place, the stronger the wind. When a gust of wind blows, the pressure on the side facing the wind is strong; On the side with the wind on its back, the airflow pressure is small.

Designing the building into a shape that is thinner and thinner as it goes up can reduce the damage caused by pressure differences. Do structural design.

It is necessary to take into account that the house is subjected to vertical gravity loads, floor live loads, and horizontal wind loads.

and the role of ** (seismic resistance, seismic isolation). The construction of high-rise houses has a complete set of drawing design, review process and construction safety guarantee system. Think about it, why are there so many towering trees? It shouldn't be understood! The same goes for tall buildings.

<> the first word, China's buildings according to the importance and fortification category, from the type of structure and seismic intensity.

and the height of the house will be seismic rating.

It is divided into grades 1 to 4, corresponding to four levels: very severe, severe, relatively serious and fair! First, it leads to the deformation of the ground, so that the projection position of the center of gravity of the building changes, and even if it does not fall, it may continue to sink on one side relatively quickly in the future; Second, the building was shaken by strong ground shaking, and the structure of the building could not withstand the deformation and collapse when shaking.

For a higher return on investment, they will build the building very high. Of course, the increase in height will also increase the total cost of the building, but when the building is called a landmark in the area, its comprehensive value increase will exceed the cost increase, so investors are willing to choose a higher-rise building. From the first schematic design to the preliminary design.

and then to the construction drawings.

The design, as well as wind tunnel tests, simulation data calculations, and the need for gradual optimization, before the work begins, it can be said that all the problems before the construction and the problems that the place may face in the future are taken into account. in high-rise buildings, super high-rise buildings.

On the one hand, the fire spreads very quickly, and on the other hand, the high temperature generated by the fire can easily make the steel structure lose its strength and collapse.

Now the house is building higher and higher, but it won't fall because the foundation is well-laid, but when you see the house being built higher and higher, you don't see the foundation getting deeper and deeper.

Because there is a lot of construction technology now, and a lot of steel is used, these structures are very strong and will not fall down at all.

It is because the foundation of the house is now very deep, and the foundation is particularly stable.

Because the walls of the high-rise buildings are very strong, the foundations are also deep, and they are all connected, and the buildings covered with reinforced concrete are basically the same as those poured with molten iron after completion, so the wind does not blow. But it also has a service life, and it is possible to pour it out when encountered.

It is because the construction industry is becoming more and more advanced, and the foundation is very stable, so even high-rise buildings will not collapse.

The foundation of the house is particularly solid, and the structure is very solid. So even if it's high, it won't fall.

Each country and region has its own seismic fortification intensity, and various measures have been taken in the design and construction of buildings, such as harmonic shock absorption, so that the building can cope with the local ** damage.

Because some of the building materials are very solid now, and the foundation is very solid, it is very solid.

Because the foundation is well laid, this is the top priority of the first building, so it is decided that everything is basic. Therefore, it is very important.
