Chapter 552 The City of Stars

Chapter 552: City of Stars

The real estate project of Xingchen Technology in Yangpu District was officially announced. The exhibition center was full of guests. Luo Jia did a simple warm-up. In front of everyone.

In the hall next door, there was a project model made by 3D printing. Although it was only a model, it still shocked everyone. The towers pierced the sky like Optimus Prime. Several air bus stations at different heights indicate that it has a ground-air integrated super traffic system.

In addition, the building materials also surprised the experts present. It seems that this building does not have reinforced concrete load-bearing, but uses a kind of near-transparent composite building material, which is piled up directly on the foundation like building blocks.

Of course, what shocks people the most is the height of the building.

The city of Shanghai has always been known for its high-rise buildings, but the three major building complexes of Xingchen Technology, like the city of the sky, are high above, overlooking the entire Shanghai, including Lujiazui, which has the most super buildings.

"What the hell is this!?"

"Let's not talk about Universal and Jinmao, this height is at least twice the height of the Burj Khalifa!"

"Such a huge single building should be able to accommodate many residents."

"Crazy, Xingchen Technology is completely crazy!"

"I think it's very good. The maximum height is used to increase the floor area ratio. The surrounding green area has increased significantly, and there are even woods and creeks."

"If this kind of super community can really be built, I'd like to move in and live in it."

"You have to be able to afford it, or pay the rent. Although it is in Yangpu District, the price of a super skyscraper like this will definitely not be cheap."

People talked a lot, and they were all shocked by the magnificence of the three major building groups. The advanced design and the crazy height of the buildings made them stand out from the crowd. Compared with the surrounding buildings, the three major building groups As if from a sci-fi movie, the design and materials are far beyond their contemporaries.

"This is our answer." Luo Jia said in a deep voice: "Since the land in the city is limited, we should use the height of the building to make up for it. The design you see now is called the City of Stars. Each City of Stars consists of twelve buildings. Composed of super high-rise residential buildings, the height of a single unit is 1,858 meters, with a total of 420 floors, accommodating 80,000 residents, and 160 elevators."

"The total population of the City of Stars is close to one million. In addition to the residential areas, there are also large-scale commercial areas, restaurants, large supermarkets, schools, kindergartens, gyms, and hospitals near the ground."

"In short, all the living facilities that everyone can imagine can be found in the City of Stars, providing all-round and round-the-clock services for the people living here..."

Luo Jia talked eloquently. To put it simply, the City of Stars is a work that creates miracles vigorously. In the city, land is scarce. As a newcomer to the industry, Star Technology does not have enough land for development. In this case Under the circumstances, rational use of resources and building the floors as high as possible became their only choice.

In fact, in human history,

Or in those far-sighted science fictions, there is no lack of ideas similar to super cities. With the increase of population, cities will become larger and more crowded. High-rise buildings are almost the only way to increase the urban floor area ratio in the future. choose.

"I know, facing the City of Stars, you must have a lot of questions to know." After a brief introduction, Luo Jia scanned the audience and said to everyone with a smile: "Any questions related to the City of Stars, any speculation and Questions, you can ask questions, if you are ready, let's start now, students who want to ask questions, please raise your right hand."

As soon as Luo Jia finished speaking, there was a swish, countless arms were raised at the scene, and there were so many people who wanted to ask questions. In the absence of an outline, allowing the media to ask questions freely is undoubtedly a test for Luo Jia, because no one Know what tricky questions people ask.

"I would like to ask, is the height of the building really 1,836 meters? How do you determine the height of the building? Don't you worry about the low oxygen and low temperature in high-rise buildings?" After roll call, a young man wearing glasses stood up and asked.

"You have not one problem, but several problems." Luo Jia said with a smile: "Kunming's altitude is 1,891 meters, and I have never heard Kunming people complain about lack of oxygen and altitude sickness. The altitude line is 2,500 meters, so even if you live on the top floor of the City of Stars, it is safe."

"As for the height of the building, believe me, that is the most irrelevant issue. Since the Kingdom Tower in Jeddah can be built to 1007 meters, and the Burj Khalifa in Dubai can be built to 828 meters. Why can't our Huaxia build higher?"

"At that time, I asked my colleagues how high the City of Stars should be built. Some said 1,200 meters, some said 1,500 meters, but in the end we accidentally designed it to be 1,836 meters. "

"What does 1,836 meters represent?"

"Nothing special. The world's tallest building, Jeddah Kingdom Tower, and the world's second tallest building, the Burj Khalifa, add up to 1,835 meters, while our city of stars is 1,836 meters. It means one meter taller than their combined."

Puff~

As soon as Luo Jia's words fell, the scene was already bursting with laughter.

"Awesome! One meter taller than the world's number one and world's number two combined? Xingchen Technology is awesome!"

"Great job! I like to watch the scene where the tough guy's battle strength explodes against others, 1,836 meters, the big dog is dumbfounded this time!"

"One thousand eight hundred and thirty-six meters by accident? My God, how careless these straight men of Xingchen Technology are!"

"Let's see who is spared by the heavens. The big dogs would never have thought that they would have today!"

There was a lot of discussion among the masses, and a strong sense of pride emerged spontaneously.

For big dogs, most Chinese people don't like it. As a typical example of getting something for nothing, they discriminate against women. Thousands of princes are corrupt and various. They are completely slave-making styles of ancient clans and tribes, and they do not belong to modern countries at all.

The crude oil business has been severely suppressed by Xingchen Technology. In recent years, the big dog has lived a miserable life. If this continues, he will go back to the desert to release camels. So he made up his mind and used his family savings to engage in tourism and sell real estate.

But a barren place like the desert has a fart of tourism resources. The only way is to create it yourself, and give full play to the talent of the big dog, how to be extravagant, and how to attract attention.

People may not know that Dubai, the famous desert pearl, has not produced crude oil for a long time. Its economic pillars are tourism and real estate, plus a part of entrepot trade. We are familiar with the Burj Khalifa, the six-star Burj Al Arab, and the splendid shopping malls. , In fact, they are all gimmicks made by Dubai to attract tourists, otherwise no one would go crazy to travel to the desert. If the desert is suitable for the development of tourism, the Sahara Desert would have been lifted out of poverty long ago.

The birth of the City of Stars has dealt a severe blow to the wealthy households who are transforming into tourism and real estate. You must know that each City of Stars consists of twelve huge buildings of 1,836 meters. In a district of Yangpu, Xingchen Technology will build three cities of stars. The Jeddah Kingdom Tower, the Burj Khalifa, and the city of stars are not enough to see.

"You guys are really brave enough, 1,836 meters? One million inhabitants? Has such a super building been scientifically proven? In case of any accident, can your Xingchen Technology take responsibility!?"

At this time, a stern question came from the crowd. Luo Jia frowned slightly, and followed the voice, and saw a group of real estate bosses surrounding Boss Yang. I wish I could swallow Luo Jia alive.

If the City of Stars project can be completed, the current real estate companies will inevitably face great difficulties. Three million residents will be resettled on three small pieces of land in Yangpu District. Such a terrifying plot ratio will greatly dilute the land price.

As we all know, the largest part of the housing prices in Shanghai is the land, which can be called every inch of land. If the floors are built high, the land price allocation will be low. Although the city of stars is like traveling from the future, the appearance is extremely shocking, but the city of stars is as ordinary as the same area. Compared with real estate, it is hard to say who has the lower cost. If the cost of Star City is 30% lower than that of other real estate developers, it will establish a crushing commercial advantage.

Facing the question from the real estate developer, Luo Jia smiled, "Talking about the height of the building without talking about the building materials is simply playing hooligans. The so-called safety depends on the level of technology. If the level of technology is low, no matter how low the height of the building is, it is dangerous. If the level of technology is high, It is also safe for the height of the building to penetrate the sky!"

"If you don't believe me, you can take a look at our No. 1 elevator. Its altitude is 36,000 kilometers, and it goes directly from the surface to the synchronous orbit!"

After a pause, Luo Jia spoke fast, and said to those real estate bosses: "Assuming that the bosses have studied material mechanics, they will know that, assuming that the cross-sectional area of ​​a building is a, the compressive strength is σ, and the gravity is γ, When the height reaches h, the volume of the whole tree trunk is the area multiplied by the height, and the weight of the whole building is the volume multiplied by the gravity."

"Since the bottom of the building bears all the gravity, we multiply the compressive strength by the area to get the expression of the limit state, h=σγ."

"Take common reinforced concrete as an example. C30 concrete has a nominal strength of 30 MPa and a weight of about 25 kN per cubic meter. Then its theoretical limit height is 1200 meters. Once this height is exceeded, the building will be destroyed by its own The weight crushes."

"The strength of titanium alloy is about 900 MPa, and the weight is 44 kN per cubic meter. Assuming we use titanium alloy to make buildings, the theoretical limit height is 20454545 meters."

"It should be noted that the strength of titanium alloy is three times that of steel, but the weight is only half of that of steel. Therefore, the limit construction height of titanium alloy is six times that of steel. This is what we call light weight and high strength of structural performance."

"Lightweight and high-strength is one of the most important theories in material mechanics and architecture, and our graphene and carbon fiber are typical light-weight and high-strength perfect materials. Now, bosses should understand? 1,800 meters is right For us, it’s just pediatrics.”

So bullying!

All the real estate bosses were stunned, their expressions were extremely ugly. Luo Jia was from a technical background, and these real estate bosses knew the mechanics of materials.

"Any other questions?" Luo Jia looked around with a smile on her face.

The City of Stars is the result of the miraculous efforts of straight men in science and technology. As for why he is obsessed with transforming big cities, it is mainly to cooperate with the actions of the national team.

In December 2019, the country officially established a development plan with big cities as the core, and tilted resources towards big cities and regional central cities. Assuming you live in the core cities at this moment, then you are lucky, because in the next few decades , you will enjoy more fruits of economic development, and if you live in small and medium-sized cities and rural areas, you should consider migrating to central cities.

This is like choosing a major in university, and I have told you that the 21st century is the century of computers and information, but you choose to study civil engineering. Then you can go to the construction site to move bricks after graduation, but you can’t complain someone else.
