Steel Structure One Of The Main Types Of Building Structure

- Nov 06, 2017 -

Steel-based structure, is one of the main types of building structure. Steel is characterized by high strength, light weight, good overall rigidity, deformation ability, it is particularly suitable for the construction of large-span and ultra-high, super-heavy buildings; material homogeneity and isotropic, is an ideal elastomer , Most in line with the basic assumptions of general engineering mechanics; material plasticity, good toughness, can have a larger deformation, can withstand dynamic loads well; construction period is short; its high degree of industrialization, high degree of mechanization can be specialized production. Steel structure should be studied high strength steel, greatly improving the yield point strength; In addition to the new varieties of steel rolling, such as c-beam and z-shaped steel and profiled steel to meet the needs of large-span structures and super tall buildings.

In addition there is no heat bridge light steel structure system, the building itself is not energy-saving, the technology uses ingenious special connectors to solve the building's hot and cold bridge problems; small truss structure so that the cables and water pipes through the wall, construction Decoration is convenient.

The advantages and disadvantages of steel structure

1 material, high strength, light weight

High strength steel, high modulus of elasticity. Compared with concrete and wood, the density and yield strength ratio is relatively low, so under the same stress conditions, the steel structure of small cross-section, light weight, easy to transport and install, suitable for large span, high load capacity Structure.

2, steel toughness, good plasticity, uniform material, high structural reliability

Suited to withstand impact and dynamic load, with good seismic performance. Steel internal organizational structure is uniform, nearly isotropic homogeneous body. The actual working performance of steel structure more in line with the calculation theory. Therefore, high reliability steel.

3, steel manufacturing and installation of a high degree of mechanization

Steel components facilitate the manufacture of the factory, site assembly. Factory mechanized manufacturing of steel structural components, high precision, high production efficiency, site assembly speed, short construction period. Steel is the most industrialized structure.

4, steel sealing performance is good

As the welded structure can be completely sealed, can be made of airtight, watertight are good high-pressure vessels, large oil tanks, pressure pipes and so on.

5, heat-resistant steel structure fire

When the temperature is below 150 ℃, the properties of steel changes little. Therefore, the steel structure is suitable for the hot workshop, but the structure of the surface by 150 ℃ heat radiation, to be protected with a thermal shield. When the temperature is between 300 ℃ and 400 ℃, the strength and elastic modulus of steel decrease significantly, and the strength of steel tends to zero when the temperature is about 600 ℃. In buildings with special fire protection requirements, the steel structure must be protected with refractory materials to improve the fire rating.

6, poor corrosion resistance of steel

Especially in humid and corrosive media environment, easy to rust. General steel structure to rust, zinc or paint, and to be regularly maintained. For sea platform structures in seawater, special measures such as "zinc block anode protection" should be adopted to prevent corrosion.
