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.

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.

Key points of large steel structure plant construction management, analyzed from the aspects of pre-construction preparation, steel structure fabrication, and installation process, pointing out the key points and methods of steel structure plant construction management. I. Supervision (management) control key points in the construction preparation stage (1) Establishment of project management team. It is necessary to select experienced, technically capable, responsible, and cooperative personnel according to the characteristics of the project. Professional matching is required, especially the selection of the general supervisor, who must have good professional quality and service awareness; at the same time, give full play to the role of various functional departments of the unit and select a suitable supervision organization form according to the project characteristics.

1. Thickening Isolation Method: Add insulation cotton to the roof of the steel structure plant. The insulation cotton commonly used on the roof is glass cotton, with common thicknesses of 50mm, 75mm, and 100mm, and a density of 10kg/m3. The insulation cotton board can isolate most of the solar radiation and conductive heat, reducing the greenhouse effect inside the room. This greatly reduces the temperature of the plant and improves the internal temperature of the steel structure plant. The color steel plate steel structure roof with added insulation cotton has the effect of being warm in winter and cool in summer. 2. Installation of ventilation facilities: Due to the heat and water vapor generated by some machines in the steel structure plant, if this heat and water vapor are not discharged in time,

In the design of steel structure curtain walls, detailed structural drawings need to be produced based on factors such as the size, color, and material of the stone. Then, according to relevant design specifications, the seismic resistance, compressive resistance, and other relevant parameters of the nodes need to undergo mechanical calculations to ensure the safety and stability of the steel structure curtain wall application. Conventionally, the selection of stone should be based on the indoor and outdoor characteristics of the curtain wall. According to the elevation drawings and detailed drawings of each node, mechanical calculations should be performed on various parameters such as strength, water absorption rate, and seismic resistance to determine the selection of stone. Priority should be given to the characteristics, color, physical properties, and texture of the stone products, while also combining the overall design.

Steel structures, owing to their inherent advantages, are widely used in modern buildings such as bridges, industrial plants, and high-rise buildings. However, numerous quality defects have been exposed in many construction projects involving steel structures. This article mainly discusses some opinions on the common problems and rectification measures encountered in the acceptance and completion acceptance of steel structure projects in recent years. I. Some Problems and Solutions in the Construction Process of Steel Structures 1. Problems in the Production and Manufacturing of Components The plates used for gantry steel frames are very thin, with the thinnest being 4 mm. For the cutting of thinner plates, shearing should be preferred over flame cutting, as flame cutting can damage the edges of the plates.
