Usage/Applications of steel structure/steel frame/steel construction

*Characters of Structure Steel

1. Steel is characterized by high strength, light weight, good rigidity, strong deformation capacity, so it is suitable for construction of large-span, super high and super-heavy buildings particularly;

2. It with good homogeneous and isotropic, is an ideal elastomer which perfectly fits the application of general engineering;

3. The material has good ductility and toughness, so it can have large deformation and it can well withstand dynamic loads;

4. Steel structure’s construction period is short;

5. Steel structure has high degree of industrialization and can realize-specialized production with high level of mechanization.

*Steel structure application

1. Heavy industrial plants: relatively large span and column spacing; with a heavy duty crane or large-tonnage cranes; or plants with 2 to 3 layers cranes; as well as some high-temperature workshop should adopt steel crane beams, steel components, steel roof, steel columns, etc. up to the whole structure.

2. Large span structure: the greater the span of the structure, the more significant economic benefits will have by reducing the weight of the structure

3. Towering structures and high-rise buildings: the towering structure, including high-voltage transmission line towers, substation structure, radio and television emission towers and masts, etc. These structures are mainly exposed to the wind load. Besides of its light weight and easy installation, structure steel can bring upon with more economic returns by reducing the wind load through its high-strength and smaller member section.

4. Structure under dynamic loads: As steel with good dynamic performance and toughness, so it can be used directly to crane beam bearing a greater or larger span bridge crane

5. Removable and mobile structures: Structure Steel can also apply to movable Exhibition hall and prefabricated house etc by virtue of its light weight, bolt connection, easy installation and uninstallation. In case of construction machinery, it is a must to use structure steel so as to reduce the structural weight.

6. Containers and pipes: the high-pressure pipe and pipeline, gas tank and boiler are all made of steel for the sake of its high strength and leakproofness

 steel structure pipeline

7. Light steel structure: light steel structures and portal frame structure combined with single angle or thin-walled structural steel with the advantages of light weight, build fast and steel saving etc., in recent years has been widely used.

8. Other buildings: Transport Corridor, trestle and various pipeline support frame, as well as blast furnaces and boilers frameworks are usually made of steel structure.

All in all, according to the reality, structure steel is widely used for high, large, heavy and light construction.

Q:How to calculate the allowable slenderness ratio of steel structures under compression?
The slenderness ratio of the structure is I = l/i, and the radius is gyration radius.The buckling stress in the axial compression members of steel structures is only related to slenderness ratio.
Q:What are the types of steel structures
Steel structure is a structure made of steel material, and is one of the main types of building structures. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:How are the steel structures single, multi story and tall, super high-rise?
High rise: a building of 10 storeys or more with a height of less than 100 meters.
Q:Does the column of steel structure do the ground beam or do it directly?
The embedded bolt shall be accurately laid on the foundation according to the location and size. When the foundation is deep, the foundation top extends a thick short column, the pre buried bolt in short columns, pay special attention to ensure accurate position and size of bolts.
Q:Is there any difference between the rigid and rigid connections in the design of steel structures?
Consolidation is a consolidation in the full sense. It can not move and rotate itself, but the rigid joint can not move or displace, but the whole displacement is possible.
Q:Who knows what HW, HN and HM mean in steel structures?
It should be the difference between the elements added to different steels.HW is high tungsten, HN is high nickel, HM is high manganese
Q:What kind of building materials are used in steel structure engineering?
In the early stage of steel structure engineering, we should pre bury and embed the steel bar, that is, the anchor bolt. The material of the anchor bolt is Q235B. There are big and small.
Q:What is an engineering structure?
According to the materials used, the main types of engineering structures are concrete structure, steel structure, masonry structure and wood structure, etc..
Q:How can the welds in the steel structure be considered qualified?
Welding seam (English Name: weld) is the bonding part formed after welding.
Q:What does "CHS44*12" mean in steel structures?
The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
STLA is a leading manufactuer of steel structure.The annual steel structure production capacity is 400 thousand tons. We are obtained China steel structure manufacture enterprise super-grade qualification; Industrial and civil building engineering general contracting qualifications of Class One ; Steel structure engineering general contracting qualifications of Class One ;Construction project integrated design qualification of Class One and Overseas project contracting business qualification.
