Structural steel is an important part of modern constructions. With good bearing capacity, durability and high stability, steel structure has been widely used in the construction of works such as bridges, high-rise buildings or manufacturing plants.
1. Definition of steel structure
Structural steel is a system of components that are combined by welding or fastening together to create a structural framework, capable of bearing loads and reinforcing other materials such as concrete.
2. Composition of steel structure
Steel structure includes the following components:
- I-shaped, H-shaped, U-shaped, L-shaped steel bars, …
- Bolts, screws, spirals, …
- Steel sheet, steel plate
- Structural accessories: hangers, anchor hooks, hook belts, .
3. Steel structure design
Structural steel design is the process of determining the dimensions and shapes of steel structural members to ensure that they have the required load carrying capacity and stability. This design needs to be done according to international standards such as Eurocode, AISC or JIS.
4. Calculation of steel structure
Structural steel calculation is the process of checking the feasibility of structural design and determining the values of technical parameters such as steel strength, steel bar weight, steel sheet thickness, etc. to ensure that structure has the necessary load carrying capacity and stability.
5. Factors affecting steel structure
Structural steel can be affected by the following factors:
- Load: gravity of the building or temporary loads such as wind, earthquake, etc.
- Environment: wet, rainy, windy, salty, acidic, ...
- Temperature: high or low temperature
- Steel rod length: the longer the length, the greater the bending ability
6. Benefits of steel structure
Structural steel has the following benefits:
- Good bearing capacity
- Durable
- Ease of construction and assembly
- High flexibility in design and construction
7. Life cycle of steel structure
The life cycle of steel structures depends on factors such as environment, loads, etc. With proper maintenance and operation, steel structures can be used for a long time and without damage.
8. Areas of use of steel structure
Steel structure is widely used in the following fields:
- Construction of civil works: houses, villas, high-rise buildings, ...
- Industrial construction: factories, factories, warehouses, ...
- Construction of traffic works: bridges, roads, railways, ...
- Construction of irrigation works: hydroelectric plants, water tunnels, ...
9. Things to keep in mind when designing and calculating steel structures
- Choose the right standards and regulations related to the design and calculation of steel structures.
- Correctly determine the load and other factors affecting the structure for complete and accurate calculation.
- Choose the right structural steel and accessories to ensure the safety and sustainability of the structure.
- Perform rigorous quality checks on structural components prior to assembly.
- Ensure the stability and safety of the structure during construction and use.
10. Conclusion
Steel structure is an important and indispensable part of modern constructions. The design and calculation of steel structures need to be carried out in accordance with the process and standards to ensure the safety and sustainability of the work.
