Example of steel structure building

In recent years, steel structure buildings have obvious advantages over brick and concrete buildings in terms of environmental protection, energy saving, high efficiency and factory production. The 325-meter-high Diwang Building in Shenzhen, the 421-meter-high Jinmao Tower in Pudong, Shanghai, Beijing’s Jingguang Center, Bird’s Nest, the new CCTV building, the Water Cube, and other large-scale buildings have adopted steel structure, and pilot projects of steel structure residential buildings have been carried out in provinces and cities such as Beijing, Shanghai, Shandong, Liaoning, and Inner Mongolia, of which Beijing Jinchen Apartment has been listed as a demonstration project of residential steel structure system by the Ministry of Construction. High-rise steel structure buildings are commonplace people predict that the 21st century is the century of metal structure, and steel structure will become the backbone of the new construction era.

Since mankind began to use pig iron in the 1770s and cooked iron to build bridges and houses in the early 1800s, the development of steel structures has a longer history than the development of reinforced concrete structures, and it is becoming more and more viable. In the United States, low-rise buildings such as two-story non-residential buildings below the market has been more than 70% of the architectural metal products. The world has so far completed 101 super-high-rise buildings, reinforced concrete structure 16, pure steel structure 59, different forms of steel concrete mixed structure 27; can be seen that the development of steel structure will certainly prompt the rapid development of the construction industry, metallurgical industry, machinery industry, automobile industry, agriculture, petroleum industry, commerce, transportation industry.

Asia’s largest steel structure botanical pavilion – China’s Qingdao World Expo Botanical Pavilion shape planning and design for the shape of leaves. Botanical Pavilion project has a total construction area of 22,749 square meters, of which, the ground floor area of 13,522 square meters, the underground construction area of 9,227 square meters, is one of Asia’s largest steel structure botanical Pavilion, the total cost of the project is 293 million yuan.

Because of its leaf shape, it requires about 3,000 tons of steel structure, more than 14,000 assembled rods, more than 17,000 meters of welds, and more than 15,000 pieces of special glass, so the construction is difficult and the process is extremely strict. The on-site splicing and welding of the structure is particularly heavy, and the lifting is particularly difficult. The total length of the welded seams of the on-site splicing of the steel structure alone is more than 17,000 meters, which is equivalent to the welding volume of 10,000 tons of conventional steel structure project.
