My 1979

Suddenly it started to rain, and the big raindrops hit the river surface sparsely and crisply, making a crackling sound. The heavy rain rolled over like a huge waterfall from the sea, covering the sky and the earth, and the trees swayed wildly in the wind and rain.

Wu Shuping wanted to hold an umbrella for Li He, but Li He refused. He cast his gaze into the endless heavy rain and said quietly: "It's raining well. I like the rain."

Wu Shuping said, "Mr. Li, it's cold and you will definitely catch a cold if you get wet."

"No need." Li He had never felt so at ease before, and his voice was clear and firm, and he said, "It would be better if I lowered it a little bigger."

Wu Shuping wanted to say something else, but Yu Dehua rushed him aside. He accompanied Li He on the bow of the boat in the rain.

Li Hexiao asked, "Can you do it?"

Yu Dehua said grandly, "As you said, men can't say no!"

Li He laughed, and Ping Song and Yu Dehua also laughed.

After landing on the shore, the three men were all drowned.

Li He wiped the rain off his head and said, "It's great!"

Although he was shivering a little from the cold.

But looking at the broad surface of the river, it felt like "the waves behind the Yangtze River push the waves in front, and each wave is higher than the previous one." Maybe it's too pretentious, but he likes it, really likes it. The rain water soaks people thoroughly, and his mind can be clear. .

What really makes him happy is that from now on, the world-famous Lujiazui land truly belongs to him.

I felt that the Lu family's mouth was swollen, and they forgot to take off their own affairs!

You are quite motivated!

Development has come to a head in the past two years, high-rise buildings have been built, and foreigners have come in to make money. It's so good, oh, the nostrils are going to open until the waves start!

The joy in my heart is so exciting when I use Pujiang dialect!

He followed Yu Dehua into the engineering project department.

The chief engineer greeted him. He went to Germany with Yu Dehua to participate in the exhibition.

"Thank you, Mr. Yu. This time is really eye-opening. We are more confident this time!"

Seeing that several people had water on their heads and bodies, I quickly ordered people to get towels and tissues.

Li He only looked at the engineering drawings and did not interrupt.

A complete set of architectural drawings, depending on their professional content or function, has a large number, ranging from drawing catalogs to construction drawings. A set of heating and ventilation drawings alone has more than 700 pages, and this is only a preliminary plan.

Yu Dehua said, "Hard work, hard work."

The chief engineer said, "To put it bluntly, Mr. Yu, this is because you trust us, and you are paying us to practice!"

He was also very moved. The project costing 5.6 billion US dollars was handed over to them willfully!

He couldn't help but sigh! You should know that Japanese people are here during this period! They even asked for an interest-free loan to Deer Group, but Deer Group still refused!

Deer Group rejected the mature plan of the Japanese benzene people and chose a team like them with no construction experience. What else could they say!

"No wind damper?" Li He first looked at eight general design drawings and asked such a question. When a super-tall building encounters strong winds above level 6, people inside the building will feel a slight shaking. Moreover, Pujiang River is often hit by typhoons. Therefore, the building is specially equipped with such wind dampers to provide a more comfortable environment for people inside the building.

He is considered a semi-expert in mechanics, and from the perspective of force analysis, he can probably see some problems.

"Wind damper?" The chief engineer glanced at Li He doubtfully. The young man looked at the drawings as soon as he came in. He thought he was an employee under Yu Dehua, so he ignored him.

Yu Dehua hurriedly introduced, "This is the chairman of our Golden Deer Group. He came here from Hong Kong specifically for the Pudong project!"

"Chairman?" This name made the chief engineer feel even more unfamiliar.

Yu Dehua said seriously, "He is my boss! Does this make it clear?"

"Boss?" This time everyone couldn't believe it! He looked at Yu Dehua, then at Li He, a man who was steady and steady! One has no hair on his mouth! But looking at Yu Dehua's serious look, it seemed like he wasn't joking! He stretched out his hand towards Li He and said, "Hello, Chairman Li, hello, welcome to come and give us guidance!"

Yu Dehua pointed to the chief engineer and said, "This is the chief engineer, Mr. Zhu Guohao."

Li He also stretched out his hand and said, "Thank you! Just call me Li He. My hometown is Wanbei."

"Are you Chinese?" After Zhu Guohao finished speaking, he felt that the wording was a bit wrong, so he added, "Is Chairman Li from the mainland?"

Li He smiled and said, "If it's fake, I guarantee it will be replaced. Can I show you my ID card?"

"No! No need!" After Zhu Guohao said this, he became a little excited again! Is this the first skyscraper invested and built by the Chinese themselves?

This goes to another level!

The meaning is completely different!

He continued to ask, "Chairman Li, what kind of wind damper did you just talk about? I've never heard of this."

One of the engineering staff had never heard of this, and he was really ashamed.

"Never heard of it?" Li He frowned, feeling a little incredible. Could it be that wind dampers have not been applied to skyscrapers at this time? He asked, "Do you know about the dampers on the bridge?"

Damper is a device that provides resistance to motion and consumes motion energy.

Using damping to absorb energy and reduce shock is not a new technology. Various dampers have been used to reduce vibration and energy in aerospace, aviation, military, firearms, automobile and other industries. Since the 1970s, people have begun to gradually apply these technologies to structural projects such as buildings, bridges, and railways, and their development has been very rapid.

In particular, the hydraulic viscous damper, which has a history of more than 50 years, went through a long process of a large number of experiments, strict review, repeated demonstrations, and especially earthquake tests before it was accepted by the structural engineering community in the United States.

Zhu Guohao smiled and said, "Chairman Li, are you talking about the shock absorber?"

"That's right." Li He suddenly realized that the names were probably different.

Zhu Guohao said, "The winning bidder currently selected by Mr. Yu is an American company. They only gave a preliminary design drawing, and the complete drawing will not be completed until New Year's Day. And we have communicated with Canadian designers, and they have not mentioned it. What shock-absorbing measures?”

Li He shook his head and said, "There must be a wind damper."

With or without it, it's a completely different experience in terms of comfort.

He still explained the principle of the wind damper to Zhu Guohao in detail.

The damper is not a fancy thing. It actually uses a mass block and a sling to form a giant compound pendulum. Its resonance with the main structure can reduce the shaking of the building. Later, it became a little more complicated, that is, the damping system using eddy current technology is used to reduce the amplitude of the mass block and consume the wind vibration input energy.

Zhu Guohao was greatly shocked by Li He's attainments in mechanics. He gave a thumbs up and said, "You are really an expert in this field!"

Hiramatsu said arrogantly, "Our boss is a professor of physics!"

ps: thank you. Thank you so much.
