The steel member refers to a steel structural composite member capable of bearing and transmitting loads connected by cold bending or welding of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through connectors.
Carrying capacity:
Practice has shown that the greater the force, the greater the deformation of the steel member. However, when the force is too large, the steel members will fracture or severe and significant plastic deformation, which will affect the normal work of the engineering structure. In order to ensure the normal working of engineering materials and structures under load, it is required that each steel member should have sufficient load-bearing capacity, also known as bearing capacity. The bearing capacity is mainly measured by the sufficient strength, stiffness and stability of the steel member.
Sufficient strength
Strength refers to the ability of a steel component to resist damage (fracture or permanent deformation). That is to say, no yield failure or fracture failure occurs under the load, and the ability to work safely and reliably is guaranteed. Strength is a basic requirement that all load-bearing members must meet, so it is also the focus of learning.
Sufficient stiffness
Stiffness refers to the ability of a steel member to resist deformation. If the steel member undergoes excessive deformation after being stressed, it will not work properly even if it has not been damaged. Therefore, the steel member must have sufficient stiffness, that is, no stiffness failure is allowed. Stiffness requirements are different for different types of components, and relevant standards and specifications should be consulted when applying.
Stability
Stability refers to the ability of a steel component to maintain its original equilibrium form (state) under the action of an external force.
The loss of stability is the phenomenon that the steel member suddenly changes the original equilibrium form when the pressure increases to a certain degree, which is referred to as instability. Some compressed thin-walled members may also suddenly change their original equilibrium form and become unstable. Therefore, these steel components should be required to have the ability to maintain their original equilibrium form, that is, have sufficient stability to ensure that they will not be unstable and damaged under the specified conditions of use.
The instability of the pressure bar generally occurs suddenly and is very destructive, so the pressure bar must have sufficient stability.
In summary, in order to ensure the safe and reliable working of steel members, members must have sufficient bearing capacity, that is, have sufficient strength, stiffness and stability, which are the three basic requirements for ensuring the safe work of components.
Metal fabrication is the creation of metal structures by cutting, bending, and assembling processes. It is a value-added process involving the creation of machines, parts, and structures from various raw materials.
Metal fabrication usually starts with drawings with precise dimensions and specifications. Fabrication shops are employed by contractors, OEMs and VARs. Typical projects include loose parts, structural frames for buildings and heavy equipment, and stairs and hand railings.

The steel component system has the comprehensive advantages of light weight, factory-made manufacturing, fast installation, short construction cycle, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has more The unique advantages of the three aspects of development, in the global scope, especially in developed countries and regions, steel components have been reasonably and widely used in the field of construction engineering.
Application:
Compared with ordinary reinforced concrete structures, steel structures have the advantages of homogeneity, high strength, fast construction speed, good seismic resistance and high recovery rate. The strength and elastic modulus of steel are many times higher than those of masonry and concrete. Under the same conditions, the weight of steel components is light. From the perspective of damage, the steel structure has a large deformation omen in advance, which belongs to the ductile failure structure, which can detect the danger in advance and avoid it.
The steel structure workshop has the advantages of overall light weight, saving foundation, less materials, low cost, short construction period, large span, safety and reliability, beautiful appearance and stable structure. Steel structure workshops are widely used in construction industries such as large-span industrial plants, warehouses, cold storages, high-rise buildings, office buildings, multi-storey parking lots and residential buildings.
Steel structure installation:
Prefabrication of steel elements:
The prefabrication and assembly of steel components are carried out on the steel platform according to the installation sequence and process requirements, and the welding quality must be guaranteed.
The distance between the splicing flange plate splicing seam and the web splicing seam of the profiled steel should be greater than 200mm. The splicing length of flange plates should not be less than 2 times the plate width; the splicing width of web plates should not be less than 300mm, and the length should not be less than 600mm.
In order to facilitate the welding and ensure the welding quality, try to make butt welding on the steel platform on the ground steel platform according to the size of the construction drawing, as far as possible, the stiffener plates, connecting plates, backing plates, and beams (beams) on the columns and beams.
In addition to the fabrication and assembly of prefabricated steel components on the steel platform according to the construction drawings and specifications, the manufacturability of on-site installation and changes in installation dimensions should also be considered.
