The Detail of Steel Structure Buildings

QINGDAO, China - Oct. 8, 2020 - PRLog -- The steel structure buildings are the building in which the load-bearing structure made of building steel. The main structure is usually composed of beams, columns, truss and other members made of section steel and steel plate. Purlins, bracing, and tie-beam made of C-shaped steel, round steel, angle steel, constitute the secondary structure. They are together with the enclosed structure, such as the roof, floor, and wall, which form a complete building.


Light Steel Structure Buildings

L-shaped, U-shaped, Z-shaped, and tube-shaped steels cold-rolled by thin steel plates and other small steel materials such as angle steel and steel bars constitute the load-bearing structure called light steel structure buildings.

The different between Steel structure and concrete buildings

Compared with traditional concrete buildings, steel structure buildings use steel plates or section steel instead of reinforced concrete, which has higher strength and better earthquake resistance. And because the components manufactured in the factory and installed on-site, the construction period significantly reduced. Due to the reusable steel, it can reduce construction waste and more environmentally friendly, so it widely used in industrial buildings and civil buildings.

Classification of steel structure buildings

Large-span structure

The higher the span of the structure, the more significant the proportion of its weight in the load. Reducing the self-weight of the structure will bring obvious economic benefits. Steel structure with the advantages of high-strength and lightweight, which suitable for large-span structures. Therefore, steel structures widely used in large-span space structures and long-span bridge structures.

Industrial workshop building

The primary load-bearing framework of workshops with large crane lifting capacity or heavy workload mostly apply steel structure. Besides, the workshop with radiant heat often uses steel structures.

The structural form is the portal rigid frame (https://havitsteelstructure.com/specification-of-portal-s...) or steel bent frame structure composed of a steel roof truss and a stepped column, and there are also architectural forms that use a grid structure as the roof.

The combined structure of steel and concrete

Steel components and plates must meet the stability requirements when they compressed, and they often cannot fully exert the high strength.

Concrete is most suitable for compression and not suitable for tension. Use steel and concrete together to make the two materials fully develop. It is a very reasonable structure.

In recent years, this structure has made considerable progress in China and is widely used in high-rise buildings, long-span bridges, industrial workshops (https://medium.com/@havitsteel/the-specification-of-porta...), and subway platform columns. The main components are steel and concrete composite beams and concrete-filled steel tube columns.
