Adrian searched in the box he was carrying, then took out a rolled-up drawing and handed it to Yang Jing, "This is the overall rendering of the building I designed at the time, take a look at it. To be honest, when I handed this design to Prince Alwaleed, I was actually a little reluctant, because the overall style of the building I designed is not very suitable for the folk customs in Saudi Arabia, but more suitable for you Chinese. As you know, I have designed two super high-rise buildings in China, one is the Jinmao Tower and the other is the Zifeng Tower, so I have a good impression of this country, and this design is more in line with the traditional style of China."
Yang Jing opened the rendering and was immediately attracted by the building drawn on it.
The bird's-eye view of the building showed a slightly deformed five-pointed star pattern, not a regular five-pointed star, but with some changes. As for the front view, it was a spire that looked like a triangular pyramid. The bottom of the building was the largest, but the building continued to shrink as the height increased, until it shrank to a spire at the top.
The overall look is as if a three-edged bayonet is erected on the ground, piercing the sky.
"Haha, you can see that I originally named this building the Five-Star Tower, because the overall structure of this building presents a five-pointed star pattern, and the five-pointed star also has a special meaning for China. At the same time, this building can also be called the Five Elements Tower, gold, wood, water, fire and earth. In the ancient civilization of your China, the five elements are also one of the most important inheritances. The five corners of this building represent the mysterious five elements."
"Well, not bad, quite good! I like this design very much. But Ade, where did you get the inspiration for this design?"
"Haha, this is a bit of a coincidence. I have a little grandson, he is seventeen years old this year. More than ten years ago, when he was five years old, he was playing with a paper ball. The paper ball was made up of several equilateral triangular cubes, which is a toy called a five-intersecting tetrahedron."
Yang Jing nodded. He had seen this kind of origami toy before. It was a very magical toy.
"Because each face of this five-intersecting tetrahedron presents a five-pointed star shape, my inspiration suddenly came to me, so I designed this five-star tower based on the principle of this five-intersecting tetrahedron."
After a pause, Adrian continued to explain: "We all know that triangles are the most stable structure, so many main structures in super high-rise buildings are triangular. The overall structure of this five-star tower is composed of five triangles, so structurally speaking, the five-star tower has a very stable structure."
"Well, in fact, the architectural concept of the Burj Khalifa I designed before was the 'Desert Flower'. The plane is a three-petal symmetrical blooming flower; the facade forms a spiral line through 21 gradually rising terraces, and the whole building is like a budding flower. The core idea of this design is actually also an equilateral triangle structure. And the Kingdom Tower I designed is also based on the design idea of the equilateral triangle structure. If you want to build a super high-rise building, the first thing to ensure is that the core structure of the building must have sufficient stability, and the triangle is undoubtedly the best choice."
Yang Jing nodded and said, "Ade, your design concept is very correct. For such a high-rise building, stability is the first priority."
Adrian smiled and said, "That's right. So in my designs, there are almost no buildings that are entirely made of steel. The buildings I designed are mainly made of steel and concrete, and only the top floor is made of full steel structure."
"Hey, could the use of certain building materials affect the stability of the building?" Yang Jing asked puzzledly.
"Of course! The choice of building materials plays a crucial and decisive role in the stability of the building! Albert, you should know that the two things that super high-rise buildings fear the most are earthquakes and strong winds. It's hard to say about earthquakes. Generally speaking, super high-rise buildings are located in areas with relatively stable geological conditions to minimize the impact of earthquakes on the buildings. But strong winds are unavoidable. For every super high-rise building over 400 meters in height, the first thing to consider when designing is the impact of wind on the building. Because the higher the building, the stronger the wind force on its upper part, and the greater the displacement of the building. This is a proportional relationship and cannot be avoided."
"However, if different building materials are used, the impact of wind on buildings can be minimized. In the 1960s and 1970s, there was a general consensus in the global construction community that 'all-steel structures are better than concrete structures and are suitable for super-high-rise buildings'. Therefore, a large number of steel-structured high-rise buildings over 300 meters were built during that period, such as the New York World Trade Center Twin Towers built in 1971, which reached a height of 412 meters, and the Chicago Sears Tower built in 1974, which reached a height of 442 meters."
"Well, I know this. It seems that the all-steel structure is not very conducive to fire prevention. The collapse of the World Trade Center Twin Towers in the 9/11 incident was caused by the fire melting the steel structure of the building, which eventually led to the collapse of the twin towers." Yang Jing said.
"Yes, although the steel structure reduces the overall weight of the building, as you said, super-high-rise buildings with all-steel structures are a very unfavorable factor in terms of fire prevention. If the World Trade Center Twin Towers were made of concrete structure, then perhaps the twin towers would not have collapsed in the end." Adrian nodded.
