Usage/Applications of steel structure

*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

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.

 light steel structure for prefab house

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:Steel structure platform cost
Give me your drawings, the quota to be used, your construction organization plan and other relevant information to me. I'll calculate the cost for you
Q:What does steel structure 8M24 mean?
The steel structure is mainly made of steel beams, steel columns, steel trusses and other components, and each component or component is usually welded, bolted or riveted. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:How to distinguish between steel structure materials and structures, steel types and specifications?
Carbon structural steelAccording to the current national standard "carbon structural steel" (GB700) regulations, numerical grade carbon steel structural yield point represented by the letters Q, yield point (N/mm2), the quality grade of symbols and symbol deoxidization method four parts according to the order.Carbon structural steels are divided into five kinds: Q195, Q215, Q235, Q255 and Q275. The greater the yield strength, the greater the carbon content, strength and hardness of the carbon structure, the lower the plasticity. Among them, Q235 in use, processing and welding performance is better, is one of the steel commonly used in steel structure.Quality grade is divided into A, B, C, D four, from A to D that quality from low to high. Different quality grades of steel require different chemical composition and mechanical properties. A no impact on regulations, only in the cold test only when the carbon, silicon and manganese content can not as delivery conditions; the B level, C level and D level were required to ensure 20 C and 0 C, 20 C Charpy V notch impact energy is not less than 27J (longitudinal), were required to provide assurance of conformity of bending test, as well as carbon, manganese, silicon, sulfur and phosphorus content of warranty. When all steels are delivered, the supplier shall provide the quality assurance of mechanical properties such as yield point, ultimate strength and elongation.
Q:In architectural design, what are the sectional sizes of square columns and columns in various structural forms (such as concrete, steel structures, wood structures)?
Steel bearing columns are not rectangular or circular (with or without gates), they should be I-shaped (solid abdominal column) or various lattice configurations (hollow columns).
Q:Large steel structure stress analysis, what software is good?
Landlord said SW, COSMOS, 3D3S, I have not used, do not comment. As for the PKPM software is the mainstream architectural design software, the rules of the structure is more applicable. The concept of a major feature of this software is "layer" is more obvious, is relatively rigid, through the "layer" bar calculation results often appear abnormal (such as crossing the floor column and brace etc.), so the industrial equipment no floor concept, to be especially careful when using. The panel you said could not be analyzed by finite element method.But PKPM also has the advantage, that is, get started quickly, for architectural design is relatively user-friendly, you just follow the prescribed steps step by step, you can basically complete modeling. In addition, he close to domestic norms, post-processing easier.Of course, some of the PKPM modules, I did not fully use, the evaluation of PKPM may not be accurate, comprehensive, please correct me downstairs.
Q:What is a light portal steel frame?
The light portal frame is also called the light portal frame structure"The light portal frame structure is mainly refers to: the bearing structure for single or multi span portal frame, with light roof and light wall, can set up the weight of not more than 20t, light duty suspension crane bridge crane or 3T monolayer steel structure workshop.
Q:How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
You must understand that a mounting bolt is used for installation, which is now in the welding joints of steel structure connection, the first fixed installation bolt and welding, the calculation only considers the weld resistance, the bolt itself does not force, with ordinary bolt.
Q:The position of the steel structure requires a spring cushion for mounting the bolt
Steel structure is mainly made of steel material, and it is one of the main types of building structure. 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. The characteristics of the steel is of high strength, light weight, good integral rigidity, deformation ability, it is used in the construction of large span and super high and super heavy buildings especially suitable; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness that can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high mechanization degree.
Q:What is the rib of steel structure?
A strip reinforcement provided at a support or at a concentrated load to ensure local stability of the member and transfer of concentrated force
Q:What can be painted on the surface of steel structure to prevent rust and corrosion?
Bridge steel structure (ordinary type): primer is epoxy zinc phosphate primer, intermediate paint is epoxy micaceous iron intermediate finish, acid polyurethane paint
