Introduction to the advantages of steel structure building?

Steel structure building, a new building system, has the industrial boundaries of real estate, construction and metallurgy. It is a new industrial system and is generally optimistic about steel structure building system in the industry. Among them, what are the advantages of steel structure building? The following is an introduction to the advantages of steel structure buildings brought by the construction network for reference.

Advantages of steel structure building

The "ratio of bulk density to strength" of steel is generally less than that of wood, concrete and masonry, so the steel structure is lighter, 30%-50% lighter than the reinforced concrete structure; In addition, the steel structure has a smaller cross section, which can increase the effective building area by about 8% compared with the reinforced concrete structure. The Songhua River Steel Truss Bridge, Yellow River Bridge and Shanghai International Hotel built in the early 20th century all adopted steel structures. After the founding of New China, the development speed of steel structure of civil high-rise buildings in China has been further accelerated. Among the dozens of high-rise steel structures in China, Beijing has six: Jingguang Center (208 meters high), Jingcheng Building (0/82 meters high), Guomao Building (0/55.2 meters high), Changfugong Hotel (90.9 meters high) and Shangri-La Hotel (82.7 meters high). Hundreds of airports in China will adopt steel structure design to speed up the construction and increase the space. It can be seen that high-speed economy needs steel structure.
