Common steel structures include the following types: (1) Large-span structures The larger the structural span, the greater the proportion of self-weight in the load, and reducing the self-weight of the structure will bring significant economic benefits. The advantages of high steel strength and light structural weight are ideal for large-span structures, so steel structures are widely used in large-span spatial structures and large-span bridge structures. The structural forms used include space trusses, trusses, shell structures, suspension bridges (including cable-stayed systems), cable-stayed beams, solid or latticed arches and frames, etc. (2) Industrial plants Cranes with large lifting weights or heavy working conditions

What are some ways to prevent the deformation of steel structural components? First, when manufacturing steel components, the processing technology should be determined in combination with the actual supply varieties of materials, processing technology level, and equipment conditions, etc., to reduce the stress and deformation of the components. 1) Minimize the number of steel varieties and the number of component types to prevent component stress and deformation. 2) The dimensions or hole diameter of symmetrical parts should be unified as much as possible for easier machining; this is also conducive to interchangeability during assembly. 3) Reasonably arrange weld seams, avoid weld seams being too close to each other, and when the length of the material is greater than the length of the component, reduce or avoid splice welding.

Steel is a non-combustible building material with properties such as earthquake resistance and bending resistance. In practical applications, steel can relatively increase the load-bearing capacity of buildings, meet the needs of architectural design aesthetics, and avoid the defects of building materials such as concrete that cannot be bent or stretched. Therefore, steel has been favored by the construction industry, and its use is common in single-story, multi-story, and skyscrapers, factories, warehouses, waiting rooms, and airport terminals. However, steel as a building material also has some unavoidable shortcomings in terms of fire prevention, and its mechanical properties, such as yield point, tensile strength, and elastic modulus, will all decrease with increasing temperature.

Current methods for reinforcing steel structures can be summarized as follows: 1) Increasing the member section (such as the steel bonding method); 2) Improving the structural force system (such as adding beams and columns); 3) Prestressed concrete reinforcement method. Common methods for increasing the section size include increasing the section height, thickening the flange plate, and changing the section shape to a box section. The main reinforcement methods for increasing the steel structure section are steel bonding or carbon fiber cloth pasting. These two methods have relatively little damage to the structure itself, and they have developed rapidly domestically in recent years, with increasing applications. However, they are relatively less used in the reinforcement of steel structure buildings.

When looking at the bending moment diagram of a portal frame, the bending moment can be seen, but what is the relationship between the bending moment and the member section? The bending capacity of a flexural member is Mx/(γx*Wx)+My/(γy*Wy)≤f, where W is the section modulus. The approximate section can be manually calculated according to the section modulus. How is the flat connection of 2H-shaped steel specified? It can be connected in any way, mainly considering the transfer of bending moment and/or shear force. In addition, the design of welded joints should be especially careful in places with many dynamic loads. 3 "Planing and tightening", does it mean no welding is needed after planing and tightening? Planing and tightening is a...

There isn't a unified standard to determine whether a structure is heavy steel or light steel. Many experienced designers or project managers cannot give a complete explanation. However, we can make a judgment based on some data: 1. Plant crane lifting weight: Greater than or equal to 25 tons can be considered a heavy steel structure. 2. Steel usage per square meter: Greater than or equal to 50KG/M2 can be considered a heavy steel structure. 3. Thickness of main structural steel plate: Greater than or equal to 10MM, rarely used in light steel structures. 4. In addition, there are some reference values: such as the cost per square meter, the maximum component weight, and the maximum span.
