China has a long history, and it can be said that none of the current countries in the world can match our history. The ancient buildings that have survived in such a long history have become the treasures of human civilization, but the problem is that many ancient buildings are civil structures, which are very easy to be destroyed with the passage of time, but the Forbidden City in China still stands.
This makes many Chinese and foreign engineers very curious, obviously experienced more than 200 earthquakes in 600 years, why did the Forbidden City not collapse? After studying its internal structure, I have to sigh: the wisdom of the ancient people is simply an "anti-human" operation, because the reason why the Forbidden City did not collapse was not because it was strong, but because it would shake.
Some engineers even said after studying that the special structure of the Forbidden City makes the tower more and more safe, if it is not shaken, it may collapse early, which is the most primitive earthquake-proof structure in ancient China. If you study the various ultra-tall buildings now, you will find that damping shock absorbers are often installed in the foundation to keep the building stable during shaking.
And such a high-tech-looking equipment, in the foundation structure of the Forbidden City in China has actually been found, in the Forbidden City under many huge wooden pillars can be seen to be fixed with stones, but leaving a very subtle gap, so that in the face of earthquakes or strong winds, the pillars can appear in the limited space to reduce the harm to the overall building.
Not only is there such a shock absorption structure under the pillar, in fact, the most exquisite of ancient Chinese architecture is the mortise and mortise structure, such a structure, without spending a nail to be able to closely combine building materials, and such a complex construction is also to be able to leave subtle gaps, so that it can keep the whole will not fall apart while shaking.
In addition, the Forbidden City has been repaired for 600 years, so we can see such an ancient complex of buildings that seem to have crossed out of history today, if it were not for such exquisite construction, it is estimated that it would be the same as the historical sites of other countries, only the frescoes and stone pillars can remain.
