Structural steel is important around us. Because it is excellent hardenness, durablility, corresion-resistance and lower cost, etc. You may find steel structures anywhere. Around the world, there are record-high buildings, bridges across the widest rivers, and sculptures that unite countries. However, we sometimes forget that many landmark buildings in the world, such as top 4 famous steel structures listed here, are impossible without steel.
What Is Steel Structure?
Steel structure is a metal structure made of structural steel components, which are connected to each other to carry loads and provide rigidity. Due to the high strength of steel, these structures are reliable and require less raw materials than some other types of structures (such as concrete). In modern buildings, steel structures are used for almost all types of structures, including heavy industrial buildings, high-rise buildings, equipment support systems, infrastructure, bridges, towers, heavy industrial plants, etc.
According to the specifications of each project, the section steel may have various shapes, sizes and specifications, which are made by hot rolling or cold rolling, and other sections are made by welding flat plates or bending plates. Common shapes include I-beam, high-speed steel, channel steel, angle steel and steel plate.
Advantages of Steel Structures
1. Control and management: the steel structure is manufactured in the factory and quickly installed by skilled personnel on the site for safe construction. Industry surveys consistently show that steel structures may be the best solution.
2. Creativity: steel has a natural beauty. The steel structure allows long columnless span and natural light in the structure of any shape.
3. Durability: It can withstand extreme forces or severe weather conditions, such as strong winds, earthquakes, hurricanes and heavy snow. It is also not easy to rust. Unlike wood frames, it is not affected by termites, worms, molds, molds and fungi.
4. Cost saving: steel structure is the cost leader of most materials and design projects. Compared with other traditional construction methods, its manufacturing and installation costs are relatively low and requires less maintenance.
Top 4 Splendid Steel Structure
ShunHing square tower, China Shenzen
At present, it holds the record of the largest all-steel building in China. The Shunxing Plaza Building is built four floors every nine days at an amazing speed.
Taipei 101 tower, China Taiwan
The Taipei 101 Tower is half a kilometer high, which proves the strength and durability of steel. It has 61 elevators and has been rated as one of the seven wonders of the project by Discovery Channel.
Willis tower, United States, Chicago
The Willis Tower in Chicago, formerly known as Sears Tower, is a remarkable building worth seeing. It is like that several unique buildings of different heights are bolted together to enhance their ability to withstand the famous strong wind in Chicago. Steel plays an important role in the structure of Willis Tower, because the steel frame connects all parts of the building together.
Burj Khalifa, Dubai
At present, the highest man-made building in the world, the Burj Khalifa, is 829.8 meters high. The building is designed with bundled pipes to reduce the amount of steel required. It has 163 floors, an 11-hour long park and a 275-meter long fountain, which can spray 150 meters of water into the air. Interestingly, the number of steel bars used is 31400 metric tons, which will be extended by a quarter in the world.
