Steel pipe structure classification|Steel pipe structure characteristics|Structural advantages of steel pipe The following information is provided by Shandong Seamless Steel Tube Factory (): The current steel pipe structure used in the project can be classified according to the cross-sectional shape, structure and manufacturing methods. According to the cross-section, the steel pipe structure can be divided into three types: round pipe structure (CHS), square (moment) pipe structure (RHS) and other shapes. Because of its superiority in appearance and force performance, the circular tube structure and square tube structure are the most widely used. According to the structural form, the steel pipe structure can be divided into four types: grid frame, lattice frame, frame and concrete-filled steel tube structure. The structural form of steel pipes refers to the use of round pipes and square pipes as the components, and the pipes and pipes are connected in the form of continuous welding. According to the production method, the steel pipe structure can be divided into three types: hot-rolled steel pipe structure, cold-rolled steel pipe structure, welded steel pipe structure. Hot-rolled steel tubes have thicker wall thicknesses and higher production costs. Cold-rolled steel tubes have relatively thin wall thicknesses.
The characteristics of round pipe and square (moment) steel pipe structure are as follows: Circular pipe and square (moment) shaped sections have biaxial symmetry, cross-section centroid and shear center coincidence; round pipe and square pipe section, moment of inertia of the section The same as each axis, as the most prominent advantages of bending and compressive members; Closed section, large torsional stiffness, local stability of the plate, especially round pipe section, the distribution of the polar axis of the section is uniform, the resistance torque is particularly effective; appearance is simple , smooth, the rod can be welded directly to the same point, without the gusset plate, in order to save steel.
Compared with ordinary steel structure, the advantages of steel pipe structure are as follows: 1. Compared with ordinary open section steel, the round pipe and square (moment) section have the characteristics of smooth surface, no dead angle and small external surface area, etc. This will help save corrosion and fire retardant coatings and facilitate dust removal. Second, the wind resistance coefficient of the steel pipe section is small, and it has significant advantages when applied to exposure to fluids (such as wind and water). Third, the internal space of the steel pipe structure can be used. For example, filled concrete (steel-concrete-concrete structure) can not only increase the bearing capacity of the components, but also extend the fire resistance of the components (on average, up to 2 hours). Water in the pipes can be used for internal fire protection. Fourth, the pipe can transfer liquids. At present, oil pipeline bridges and rainwater drainage pipes have been developed based on this feature. Fifth, prestressed cables can also be placed in the tube to apply prestressing in the body.
