How much does an ordinary 30-story building weigh? How many tons?

With the increase of China's population, the demand for houses has gradually increased. In recent years, houses in various cities have mushroomed, and friends can often find an interesting phenomenon. Generally, the tallest building you see is only 33 stories, but it rarely exceeds 33 stories. Why?

In fact, this is linked to the interests of developers. In China, there are strict restrictions on super high-rise buildings above 100 meters. If the height is 3 meters, the 33rd floor just reaches 99 meters, and one more floor will become a 100-meter building, because the higher the floor of the building, the more factors need to be considered. The design concept and construction technology of super-high-rise residential buildings are much more complicated than ordinary high-rise residential buildings and middle-low-rise residential buildings.

There are many factors to be considered, such as the number of elevators installed in the ventilation and smoke exhaust equipment of the building, emergency fire fighting facilities and personnel evacuation facilities. Developers also build houses to make money, so when building houses, they will try to choose the most cost-effective building method. A 33-story house can maximize the interests of developers.

And once it exceeds 100 meters, it also represents the image of a city because of its outstanding height. Therefore, developers should be tall and graded when decorating the external walls of buildings, which also increases the cost, and at the same time, the seismic capacity and bearing capacity of super high-rise buildings themselves will be greatly enhanced. So generally speaking, developers will naturally not choose to invest in super-high-rise buildings above 100 meters.
