Steel Structure Has Been Widely Used Jun 05, 2017



Steel structure is composed of steel material structure, is one of the main building structure type. The structure is mainly composed of steel and steel plate, steel column, steel truss and other components, the components or components are usually used between the weld, bolts or rivets connected. Because of its relatively light weight, and the construction is simple, widely used in large factories, venues, high-level areas.

Steel is characterized by high strength, light weight, Steel Structure the overall stiffness is good, deformation ability, it is used to build large span and high, super heavy-duty buildings particularly suitable; material homogeneity and isotropic, is the ideal elastomer , The most suitable for general engineering mechanics of the basic assumptions; material plasticity, toughness, and may have a greater deformation, can withstand the dynamic load; construction period is short; its high degree of industrialization, Steel Structure can be highly specialized mechanized production.

Steel structure should be studied high strength steel, greatly improve its yield point strength; in addition to rolling new varieties of steel, such as H-shaped steel (also known as wide flange steel) and T-shaped steel and pressure plate to adapt to large span structure and Super high-rise building needs.

In addition, there is no thermal bridge light steel structure system, the building itself is not energy-saving, the technology with clever special connection to solve the building's hot and cold bridge problem; small truss structure of the cable and the upper and lower water pipes from the wall through the construction Decoration is convenient.

Commonly used steel structure building, there are some types: (1) large span structure

The greater the structure span, Steel Structure the greater the proportion of the weight in the load,

Reduce the structure of the weight will bring significant economic benefits. Steel strength and high structure of the advantages of light weight is just suitable for large span structure,

So the steel structure is big

Cross-space structure and large span bridge structure has been widely used. The structure used in the form of space truss, grid, reticulated shell, suspension (including the cable system), beam string, solid or lattice frame and frame. (2) industrial plants

Crane from the larger or more heavy work of the main load-bearing skeleton of the use of steel structure. In addition, there is a strong radiant heat of the workshop, Steel Structure often used steel structure.

The structure is mostly made of steel roof truss and stepped columns of the door frame or frame, but also the use of grid structure to do the form of roof. In recent years, with the use of lightweight roofing materials such as pressure plate,

Light steel structure industrial plant has been rapid development. Its structure is mainly for the real-type variable cross-section door frame. (3) Structure affected by dynamic load As the steel has good toughness, with a large forging hammer or other power generation equipment,

Even if the roof span is not large, it is often made of steel. For structures with high seismic capacity requirements,

The use of steel structure is also more appropriate. (4) multi-storey and high-rise buildings due to the comprehensive benefits of steel structure indicators, in recent years,

High-rise civil buildings have also been widely used. Steel Structure Its structure mainly has multi-layer frame, frame - support structure, frame tube, suspension, giant frame and so on.

(5) tall structure

High-rise structures include towers and mast structures such as towers for high-voltage transmission lines, towers and masts for broadcasting, communications and television launches, and rocket (satellite) launch towers.
