I. Introduction. As an important form of building structure, steel structure technology has occupied an important position in China's construction industry. There are many types of steel structures, and different types have different characteristics and scope of application. This article will analyze the types and development trends of steel structure technology.
Second, the type and characteristics of steel structure.
High-rise steel structure building.
High-rise steel structure building is an important type in steel structure technology, its main characteristics are large building height, complex structure, high requirements for the stability, strength and rigidity of steel structure. In high-rise steel structure buildings, the common structural forms include frame structure, cylinder structure, giant frame structure and hybrid structure.
Large-span steel structure building.
Large-span steel structure building is another common type of steel structure technology, which is mainly characterized by a large building span and high requirements for the mechanical performance and stability of the steel structure. The common structural forms of long-span steel structure buildings include truss structure, grid structure, suspension structure and membrane structure.
Low temperature steel structure building.
Low-temperature steel structure building is a type of steel structure technology developed for the construction needs in low-temperature environments. Its main feature is that the building needs to maintain stable structural performance in a low-temperature environment, and has high requirements for low-temperature toughness, brittle fracture resistance and anti-corrosion performance of the steel structure. The common structural forms of low-temperature steel structure buildings include cold storage, cold storage, cold chain logistics center, etc.
Marine steel structure building.
Marine steel structure building is a type of steel structure technology developed for the construction needs of the marine environment. Its main feature is that the building needs to maintain stable structural performance in the harsh marine environment, and the steel structure has high requirements for anti-corrosion performance, wind resistance and wave impact resistance. The common structural forms of marine steel structure buildings include offshore wind power towers, offshore platforms, docks and docks.
Third, the development trend of steel structure technology.
Green and environmentally friendly. With the improvement of environmental awareness, steel structure technology will also develop in the direction of green environmental protection. This includes the use of sustainable steel, improving the utilization rate of steel structures, reducing construction waste, etc.
Intelligent. In the future, steel structure technology will develop in the direction of intelligence, including the use of intelligent design software, the use of robots for the construction and installation of steel structures, and the use of Internet of Things technology for health monitoring of steel structures.
Performance. The performance of the steel structure will be further improved, including improving the strength, stiffness and stability of the steel structure, improving the seismic performance and wind resistance of the steel structure, etc.
Large span. Large-span steel structure buildings will become the future development trend, including the development of new long-span steel structure forms, and the improvement of the performance and stability of long-span steel structures.
IV. Conclusions. To sum up, there are many types of steel structure technology, and different types have different characteristics and scope of application. In the future development, steel structure technology will develop in the direction of green environmental protection, intelligence, high performance and large span. This will help improve the performance and quality of steel structure buildings, meet the growing floor area and functional needs, and promote the development of the construction industry.
