1. What is a steel structure?

Structural steel is one of the materials used in various steel constructions and has specific shapes. This steel material complies with specified standards for chemical composition and proper strength. The demand for the construction of steel structure buildings is increasing and is used in many projects such as bridges, stadiums, warehouses, industrial facilities, and other infrastructure projects.

Structural steel is one of the materials used in various steel constructions and has specific shapes.

Steel structures can be classified into the following types:

  • Plate girders
  • Frame buildings
  • Steel arch bridges
  • Industrial buildings
  • Transmission line towers

2. Main structural types in steel structure 

Each structural steel type serves different purposes and offers unique advantages based on the specific requirements of the construction project. However, the main structural types in steel structures include: 

  • Frame structure: Beams and columns 
  • Grid structure: Lattice structure or dome 
  • Truss structure: Bar or truss members 
  • Arch Structures 
  • Shell Structures 
  • Cable Structures
  • Bridge structures: beams, cables, arches, suspensions, trusses

3. Advantages of steel structure 

Structural steel is a popular and reliable choice for a wide range of construction projects, from commercial and industrial buildings to bridges and other infrastructure developments, because of its advantages and outstanding points such as: 

  • Durability: Structural steel building is resistant to decay, corrosion, and pests, resulting in long-lasting structures. 
  • Speed of Construction: Prefabrication and ease of assembly lead to faster construction times. 
  • Design Flexibility: Steel allows for versatile and creative architectural designs. 
  • Sustainability: The steel structure is recyclable, making it an environmentally friendly choice. 
  • Cost saving: Reduced labor and construction time often result in cost savings. 
  • Safety: Steel structures offer excellent performance during seismic events and high winds. 
  • Maintenance: Low maintenance requirements contribute to long-term cost efficiency. 
  • Expansion and Adaptation: Steel structures can be easily modified or expanded. 
  • Fire Resistance: Properly designed steel structures can provide high fire resistance.

4. What are the standards of steel structure?

The standards of steel structures are intended to determine the quality of steel structures used for construction. 

For example, the constructions must meet the standards of Vietnam, Australia, the USA, the UK, and Europe. 

Once the standards have been identified, this will be the basis for constructing, controlling, and accepting steel structure constructions.

5. Steel structural standards in Vietnam 

Currently, the standard of steel structure is the national standard TCVN 5575: 2012. This standard has the following features:

  • Originating from Russia with the code SNIP II -23 – 81, compiled by the Institute of Construction Science and Technology – Ministry of Construction, Ministry of Construction proposed, General Department of Standards and Quality appraisal, Ministry of Science and Technology announced.
  • As the National Standard as prescribed in Clause 1, Article 69 of the Law on Standards and Technical Regulations and Point B, Clause 2, Article 7 of the Government’s Decree No. 127/2007/ND-CP on August 1st, 2007 detailing the implementation of several articles of the Law on Standards and Technical Regulations.
  • Applicable to steel structural design of civil and industrial constructions; not used to design transport and irrigation constructions such as bridges, road constructions, valve doors, pipes,…
  • TCVN 5575: in 2012, apply the restricted state method with safety coefficients for load, materials, working conditions …
  • TCVN 5575: in 2012, it focused on hardness and did not accept the deformation of the structure’s shape. 
  • TCVN 5575: in 2012, apply the formula:
  • Calculation intensity = standard intensity/material safety coefficient. 
  • Calculation load = standard load/overlay factor (load reliability coefficient)

In case the steel structure has many effective loads, add the simultaneous load reduction coefficient of the loads.

7. FAQ about Steel Structure? 

1. What is a steel structure called? 

Steel structure, also known as a “steel frame structure” or simply a “structural steel” system, is one of the materials used for any steel construction; it is formed with a specific shape 

2. What are the four types of steel structures? 

The four main types of steel structures are basic building frame structures, portal frames, truss structures, and grid structures, each serving specific construction purposes and engineering requirements.
