Steel Structure Building Structure Types

The structural types of steel structure building are traditional structural type, integral tensioning type and hanging structural type.

1, traditional structure type

Traditional steel frame type is the main steel frame type structure in our country, and its high efficiency and energy saving lies in the fact that we can install and arrange the cable system to apply the pre-stressing force on this kind of structure, to improve the force state and capacity range of each component, to reduce its own weight and to reduce the input cost, like the National Stadium, Bird's Nest, this kind of mesh-like building is the traditional steel type structure. structure.

2. Integral tension type

There are some innovative structural systems, which no longer use the traditional steel bending parts in the overall dimension and span structure, and all of them are changed to be made up of tensioned cable system, smooth membrane surface and high-precision pressurized precision rods, which is characterized by the lightness of the high-level top structure and the novelty of the innovative ideas of design, and it belongs to the advanced and excellent structure of the steel structure.

3, hanging structure type

Hanging structure type, this kind of steel structure is mainly composed of vertical structural support system, including vertical columns, door frames, arches and so on, which requires high-precision support system, it is a lot higher than the roof, the pre-stressing of the cable system adjusts the stress point, adjusts the internal force of the roof cover and forms the elastic force of the roof, which is lifted up from the ground to point to the blue sky, which is very recognizable. It has a very high degree of recognizability.

Characteristics of steel structure

1, the raw material used in steel structure is steel, which is stronger and lighter in weight compared with concrete and wood, and is easy to be transported and installed.

2. It is suitable for structures with large spans, high heights and heavy loads, such as large-scale factories, arenas, super-high-rise and other fields. And it has strong toughness, good plasticity and more uniform material, so the structure is also more reliable.

3. In addition to this, steel structure also has the advantages of good sealing, energy saving and environmental protection, which can be used as large oil tanks, pressure pipelines and so on.

4, but the steel is not fire-resistant to heat, corrosion resistance is also relatively poor, so in the use of the process requires regular maintenance and maintenance.
