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

 steel structure bridge

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

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:Definition of large steel structures
As a green environmental protection product, compared with the traditional concrete structure, it has the advantages of light weight, high strength and good seismic performance.
Q:What are the main structures and sub structures in the steel structure?
Main components: steel column, steel beam, crane beam and other large main componentsComponent: column bracing, horizontal support, tie bar, brace, casing etc.In addition to the purlin. I'm not sure whether it's the master or the second, and there's no definition.
Q:What is the cushion block in the steel structure?
In the steel structure of wedge type block is used to adjust the steel structure column or large equipment and the top surface of the base pad installed with the steel quantity.
Q:Steel structure canopy belongs to the metal structure which component? Steel roof truss? Steel wall frame? Or steel grid?
The steel wall frame generally refers to the glass curtain wall of the airport, or the windbreak wall of the coal yard. It is the wall structure, and the former two are the roof structure
Q:What are the types of steel structures
Containers closed, such as large storage tanks, gas reservoir, the furnace shell needs to accept a Chongqing steel structure with a large internal force and rapid temperature change of blast furnace structure, large diameter high pressure pipeline are shell steel structure, there are some large hydraulic lock gate structure and shell structure.
Q:What does the steel structure lug 2-240*290*12 mean?
There are no bridge steel structure, the building itself is not such, clever special connections to solve the problem of building cold bridges by using the technique of the cable truss structure; small and water pipes through the wall, construction decoration is convenient.
Q:What does "pre assembled" of steel structure mean?
If a truss of 40 meters, 20 meters and transport only, need to ensure on-site docking, on-site installation, processing plants need to be pre assembled, truss butt in the factory, to see if there are errors, timely correction, and then segmentation approach
Q:What are the raw materials of steel structure?
Steel column, steel beam, column bottom plate, steel beam connecting plate, column beam connecting plate and so on, the material of these parts should be decided according to the design requirement.
Q:How can the steel structure be divided into Liang Hezhu?
The two are not the same, lies in the seismic design, allowing the beam stiffness is greatly reduced, in some cases it can even be allowed to quit the job, but the beam stiffness only allowed to reduce, and not allow it to withdraw from work, so the specification of secondary beam is not resting on the coupling beam however, secondary beams could take on the frame of the. General beam cross height is small (less than 5), with shear transfer, so the specification provides some of the beams and frame beam different in structure, is a requirement of coupling beams is encrypted and frame beam stirrup length can be divided into encryption area and non encrypted area, two is the reinforcement on the beam waist the made clear that "wall horizontal distribution reinforcement should be the waist beams through continuous beam configuration in the range when the beam section height pull; more than 700mm, the two sides of the longitudinal structure of reinforced beam is arranged along the high range (waist band) diameter should not be less than 10mm, the distance should not be greater than 200mm; cross ratio not more than 2.5 of the beam, the longitudinal structure of reinforced beams (on both sides of the waist band) area of the reinforcement ratio should not be less than 0.3%" and will be incorporated into the provisions of a strong, and waist reinforcement in beams as long as the "when the beam web height h W = 450mm, in the two side beams along the height of the longitudinal structure configuration should be reinforced, each side of the vertical reinforcement (not including the upper and lower beam reinforcement and erect steel) 0.1% of the cross-sectional area should not be less than the web section area of bhw, and the distance should be less than 200mm." And not a strong clause.
Q:Can steel frames and channel steel be welded longer?
Steel frames, door frames and channel steels can be welded longer.
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.
