With the continuous progress of science and technology and the improvement of people’s awareness of environmental protection, assembly building, as an emerging form of construction, has gradually received widespread attention. Among them, high-performance steel structure, as an important part of assembled building, plays an increasingly important role in modern construction with its unique advantages. This paper will discuss in detail the application of high-performance steel structure in assembled buildings and its advantages.
1.Definition and characteristics of high-performance steel structure
High-performance steel structure refers to the structural system made of high-strength steel, which is characterised by light deadweight, high strength, good stiffness and superior seismic performance. It forms a stable spatial framework through node connection, which can effectively withstand various loading effects, and at the same time has good plasticity and toughness, which can maintain structural integrity under extreme conditions such as earthquake.
2.Application of high-performance steel structure in assembled buildings
（1）Improvement of construction efficiency: high-performance steel structure adopts factory prefabrication and on-site assembly, which greatly shortens the construction cycle and improves the construction efficiency. Meanwhile, due to its modular design, it is also convenient for maintenance and overhaul in the later stage.
（2）Enhance structural stability: High-performance steel structure has good stiffness and strength, which can effectively resist the wind load, snow load, earthquake and other natural forces to ensure the stability and safety of the assembled building.
（3） Convenient for design innovation: high-performance steel structure can be flexibly designed according to the actual needs of the building, without the restriction of traditional structural forms, thus providing more design possibilities for assembled buildings.
3.Advantages of high-performance steel structure in assembled buildings
(1) Remarkable economic benefits: compared with traditional concrete structure, high-performance steel structure has lower cost and shorter construction period, which can save a lot of investment costs for enterprises.
(2) Environmental protection and energy saving: high-performance steel structure adopts recyclable steel as the main material, which is in line with the concept of green environmental protection. At the same time, its excellent thermal insulation performance also helps to reduce the energy consumption of assembled buildings.
(3)Strong adaptability: Whether in plain areas or mountainous and hilly areas, high-performance steel structure can be flexibly designed according to the terrain and adapt to various complex geological conditions.
(4)Promote the development of construction industrialisation: the application of high-performance steel structure promotes the development of construction industrialisation, and facilitates the transformation and upgrading of the construction industry and sustainable development.
