1. Single-layer steel structure
Single-storey steel structure refers to a steel structure building with only one floor, which is mainly composed of steel columns, steel beams, and steel plates. The single-storey steel structure has the following characteristics:
1. The overall weight is light, the construction is convenient, and the construction period can be greatly shortened.
2. The design is flexible, and the flexible structure combination can be carried out according to the needs to meet different use requirements.
3. It has high strength, stiffness and stability, good shockproof performance, and is suitable for some places with high safety requirements.
Second, multi-layer steel structure
Multi-storey steel structure refers to a building complex composed of two or more floors of steel structure buildings, in which each floor building is basically the same as a single-story structure. The multi-storey steel structure has the following characteristics:
1. Safe and reliable, the top floor has a strong load-bearing capacity, and it is not easy to cause structural instability due to the superposition of floors.
2. The utilization rate of steel is high, the turnover speed is fast, and it has good economic benefits.
3. Since multi-storey steel structures are mostly used in commercial or office buildings, the structural design should also consider aspects such as external environment and aesthetics.
3. High-rise steel structure
High-rise steel structure refers to steel structure buildings with more than 10 floors, and the higher the number of floors, the higher the technical requirements. The high-rise steel structure has the following characteristics:
1. The height of the building is high, and the required steel also increases accordingly, and the wind resistance, seismic resistance, steel quality, connection method and other aspects of the structure need to be considered.
2. It has a high safety risk and needs to strictly abide by the safety management system and relevant technical specifications and standards.
3. High-rise steel structures are mostly used in commercial or office buildings, and the appearance of buildings also needs to consider aesthetics and recognizability in response to the needs of different uses and commercial competition.
When designing steel structures, it is also necessary to consider factors such as corrosion resistance, temperature deformation and corrosion, and plasticity analysis of steel to ensure the safety and stability of steel structure buildings.
