What are the wise ancients about earthquake resistance?

In ancient China, there will be **, the ancients in order to resist earthquakes, there will be many ways, such as the Eastern Han Dynasty astronomer Zhang Heng invented the geodynamic instrument, which can judge the direction of **; In ancient times, many buildings used very strong materials and structures to resist natural disasters in order to be able to withstand earthquakes.

Although in ancient times, ** was not as frequent as it is now, and the depth of ** was not as big as it is now, but there are still some **, in order to prevent **, the ancient people used wooden earthquake-resistant materials in the building, and there are some places to avoid indoors, as well as ancient houses, which are not particularly high, so the damage is also very small.

Regarding earthquake resistance, the ancients made a **instrument, and the dragon ball inside the dragon head in the direction of the occurrence will fall, so that people will know where it happened**.

I think printing is a particularly great invention, and I can't help but admire the wisdom of the ancients, especially after the advent of movable type printing, which is convenient and fast.

I was amazed by the invention of papermaking, the compass, and movable type printing by the ancients. These are all inventions that have changed the development of Chinese history.

The invention of papermaking, compass, compass and ** instrument invented by the ancients is particularly amazing to me.

The wisdom of the Book of Changes is multifaceted, the Yellow Emperor's Neijing is the originator of traditional Chinese medicine, the "Zizhi Tongjian" is the "Tao Te Ching" that talks about history and strategy, Lao Tzu talks about health, and "Dream of Red Mansions" tells you the true face of things. There are also Lu Xun, great writers, modern masters. There are also many people who know and don't know, Mozi, Confucius, Han Feizi, Zhuangzi, Wang Yangming, Xu Lingti, etc., which will make you feel that you are too ignorant.

Legend has it that it was written by Li Shimin, Taizong of the Tang Dynasty, who ordered Li Chunfeng and Yuan Tiangang, two famous celestial ministers at that time, to calculate the fortunes of the Tang Dynasty. 60 images ** of historical events between 1800 and 2000 years, including the Anshi Rebellion, which caused a sensation in Chinese history, as well as the Taiping Rebellion, the War of Resistance against Japan, including Japan's defeat, and the back picture is all god-like. This is a kind of wisdom of the ancients, relying on the theory of yin and yang, expounding the historical concept of chaos in the world for a long time, and vividly showing the political thought of Confucianism.

Some cities of the ancient Roman civilization began to use the ** heating system around 1000 BC, which conducts the air heated by the stove through the space under the floor and then comes out of the pipe inside the wall, which is the ondol heating system. Ondol heating systems are used to heat public baths and private homes. The floor is raised off the floor and leaves space in the walls by means of pillars, through which the hot and hot smoke from the stove burns passes through these bounded areas and exits through the smoke holes in the roof, which heats the room without staining it.

I know one, a study conducted by Federico Formenti of the University of Oxford and Albert Minati of the University of Milan found that skates were invented by the Finns. They made the first skates from animal bones 5,000 years ago. Ice skates are important for Finns to save energy during the harsh winter hunts.

The first ice skates to use metal pieces were found in Scandinavia, dating back to 200 AD, and were made of copper bars attached to the underside of leather shoes.

Scientists' archaeology of the Indus ruins has shown that the inhabitants of the Indus Valley civilization invented a highly standardized system using weights and measures. This technical standard led directly to the popularity of metering devices for angular and architectural surveys. The measuring device also includes many parts of the scale and possibly some of the device.

The earliest examples of these standardized measures are length, time, and weight.

Archaeologists have unearthed what is believed to be the oldest perfume in the world in Cyprus. This perfume dates back more than 4,000 years and was discovered by an ancient spice shop. Archaeologists have found at least 60 stills, mixing bowls, funnels and perfume bottles in the 4,000-square-meter factory.

So far, scientists have synthesized 4 perfumes based on perfume residues found at the site.

Plastic surgery is one of the oldest surgical procedures. Nose reconstruction surgery may have existed as early as 2000 BC in ancient India. At that time, nose amputation was a form of punishment, so much so that a method of nose reshaping using part of the forehead was invented, which is still applicable today.

There is evidence of dental procedures in the Indus Valley civilizations as early as 7000 BC. This earliest dental procedure consisted of using a drill to ** the teeth. The appearance of this ancient dental tool shows that the methods used by the ancients were reliable and effective.

After all, the ancient people did not have such advanced technology as now, and there are no new materials such as reinforced concrete, they only have tools like wood, and they are still in such poor conditions, they still built very good buildings, the ancients pay attention to the architecture is really wisdom, and even today it is difficult for us to imagine, how to build a building without a nail? And the ancients relied on this architectural wisdom to create those amazing works.

The idea of overcoming rigidity with softness is the traditional wisdom of the Chinese nation. The world-famous Tai Chi is a direct product of this thinking, and the traditional Chinese method of earthquake resistance for wooden buildings can be called the "architectural version of Tai Chi".

In fact, in ancient China, there were many ** records, and in ancient times, wars were also very frequent, so buildings will inevitably suffer all kinds of wear and tear and damage, so in this case, people have gained a lot of experience about buildings.

Different from the Western brick and stone structure building, the traditional Chinese wooden structure building adopts this kind of thinking of "overcoming rigidity with softness" when resisting the impact force, and through various ingenious measures, its goal is to minimize the powerful natural destructive force at the minimum cost. Many ancient buildings in our country have successfully withstood the test of the big ones.

For example, Dou Bao, Dou Bao is another important warrior in the earthquake resistance of ancient Chinese buildings, and it plays a role in deformation and energy dissipation like a shock absorber of a car. Historically, many buildings with buckets can resist strong strength, and the bucket groups connected by various horizontal components can form a strong overall "rigid plate", in accordance with the principle of "those who can work harder" to transmit the first force to the columns with seismic resistance, which greatly improves the safety of the entire structure.

Flexible structure, generally means to overcome rigidity with softness, and if the flexibility is used just right, it can completely resist the damage of the external environment. Therefore, ancient buildings are more earthquake-resistant than modern reinforced concrete buildings.

Generally, in ancient times, building materials are generally some wood and stone, etc., and the use of flexible structures can resist to a large extent, which can make the house more solid and show the wisdom of the ancients.

Ancient people advocated overcoming rigidity with softness, and the biggest advantage of flexible structures in the first class is to reduce the impact force, although it collapses, it will not cause major damage.

**It should be said that it is a very strong force, if you fight hard, it is easy to get hurt, if it is to overcome the rigidity with softness, it is just right.

The wisdom of the ancients is really very powerful, because ancient times are not as advanced as modern times, and they can be ****, but they will have a flexible structure when they build a house, which can be reduced when **.

When it comes to the anti-earthquake wisdom of the ancients, the wisdom of the ancients is really beyond our imagination, so the architectural attention they thought of should also be a method of overcoming rigidity with softness.

I think that the use of "flexible structure" to resist in ancient architecture may contain a kind of idea of "overcoming rigidity with softness".

Because the previous people could not measure the ** very accurately, it was necessary to integrate the building into "flexibility", in order to absorb the shock, in order to reduce the **.

Because the ancient architecture in our country attached great importance to flexible structures, I think the ancients considered that when the ** came, the house would not hurt people too much.

Overcome rigidity with softness, ancient Chinese architecture is made of wood, wood represents softness, **When it comes, the impact it creates is rigid, and wood can minimize losses.

In ancient times, in order to transmit military information, people used to set up beacons and use smoke to transmit information. Legend has it that when the wolf dung is burned, there is a large smoke that rises into the blue sky, which is also known as wolf fireworks.
