Steel Structure Building

1.the connection method of steel structure:

   welding connection or bolt connection

2.Steel structure design common norms are as follows:

  • "Steel Design Code" (GB50017-2003)

  • "Cold-formed steel structure technical specifications" (GB50018-2002)

  • "Construction Quality Acceptance of Steel" (GB50205-2001)

  • "Technical Specification for welded steel structure" (JGJ81-2002, J218-2002)

  • "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)

3.The characteristics of steel

  • Light weight steel structure

  • Higher reliability of steel work

  • Steel anti-vibration (earthquake), impact and good

  • Steel structure for a higher degree of industrialization

  • Steel can be assembled quickly and accurately

  • Large steel interior space

  • Likely to cause sealing structure

  • Steel corrosive

  • Poor fire-resistant steel

  • Recyclable steel

  • Steel shorter duration

4.Commonly used steel grades and performance of steel

  • Carbon structural steel: Q195, Q215, Q235, Q255, Q275, Q345,etc.

  • High-strength low-alloy structural steel

  • Quality carbon structural steel and alloy structural steel

  • Special purpose steel

5.Market:

Q:Steel structure canopy belongs to the metal structure which component? Steel roof truss? Steel wall frame? Or steel grid?
The canopy is divided into two parts, one is the structure of part two is part of enclosure (that is, roofing materials, such as glass, aluminum plate, color plate etc.)
Q:What are the meanings of I-beam BH300 x 200 x 6 x 8 on steel structures?
The ratio of the area of a longitudinal force (tension or pressure) to the effective area of a member (the axial compression member is a full cross section). The reinforcement ratio and the reinforcement ratio of the compression bar are calculated respectively. Formula: P =A (s) /bh (0). Here is the angle brackets below.Type: A (s) is the cross-sectional area of the longitudinal reinforcement in tension or compression zone; B is the width of the rectangular section; H (0) is the effective height of the cross section. The reinforcement ratio is a parameter that reflects the number of reinforcement.The minimum reinforcement rate is that, when the beam reinforcement ratio is very small, the beam tension zone after cracking, the steel stress tends to yield strength, the reinforcement rate is called the minimum reinforcement ratio (min). The minimum reinforcement ratio is determined according to the principle that the ultimate flexural capacity M (U) of the member section is equal to the bending moment M (CR) equal to the tensile moment of the concrete member under tension.
Q:What are the differences between steel structure design and reinforced concrete structure design?
Design of steel structure and reinforced concrete structure design of reinforced concrete and to consider the difference between the two materials in the combined performance of the reinforced concrete structure design, and the design of steel structure (steel plate, only considering the beam and column and shell) performance.
Q:What does the steel structure lug 2-240*290*12 mean?
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. Steel structure of high strength steel, greatly improve the yield strength of steel rolling; in addition to the new varieties, such as H steel (also called wide flange steel) and T shaped steel and steel plate to meet the needs of a large span structure and high-rise building.
Q:Why should we add air holes to the embedded parts of the steel structure?
The embedded piece is too big, and the air vent is also called an overflow hole, and the vibrator can be inserted into the vibrating concrete from the hole, and the concrete under the embedded part is more compact and clings to the embedded part
Q:Name of steel structure awning
With high strength aluminum alloy material, the joint of column and ceiling is strengthened with galvanized steel structure, so it is more secure and firm. The surface of aluminum alloy is treated by powder electrostatic spraying, and the oxidation resistance is more than 30 years.
Q:How to consider the influence of base displacement on steel structure
When performing the structural search and acceptance, the steel structure is completed after installation. Often issued axis displacement, the vertical deviation is too large and the height of the column column below the design elevation. In the high-rise steel structure engineering, it is also found that the spacing of each column is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent when searching the top of each layer.
Q:What does the name below the steel structure of the pillars of the corner piece of iron bolt connection called ah
Steel column base, usually has two connections, and a lower anchor bolt, according to the column size, set 2, 4, 6 or more pieces of anchor bolts, no embedded parts (that is, in the above concrete plate), installation of steel column, a regulating nut is arranged in the column bottom plate anchor bolt, steel column base plate column falls directly on the adjusting nut, the flatness of the steel column to adjust the adjusting nut.
Q:What kind of building materials are used in steel structure engineering?
Support: round steel, steel pipe, welded pipe, bushing, angle steel, etc..
Q:Why steel buildings have the best seismic performance?
The plastic deformation of steel is strong, it can consume seismic energy, and there is still good resistance when plastic deformation occurs.
