Steel structure occupies a significant position in construction projects, and its stability and strength are directly related to the overall quality of the construction project. Therefore, in building projects, it is necessary to optimize the design of steel structure building continuously. To improve the stability and quality of steel structures.
Design of Steel structure building:
The steel structure’s main component is steel, and the structure of the steel building system is relatively uniform. When the steel structure’s force is consistent with the engineering mechanics design test results, the steel structure’s calculation theory will be effectively applied and improved. The steel structure has the characteristics of simple manufacturing, short construction period, and strong airtightness. It is suitable for structures with strict airtightness and water tightness requirements.
At present, poor corrosion resistance, heat, and fire resistance of steel structures have been effectively improved. The application range of steel has also increased. The main component of steel structure design is the connection of rods. The key is to apply mechanics to scientifically handle the relationship between each component’s arms and moments and to connect each node reasonably effectively.
The main points of steel structure building design
Reinforce the design of steel structure building
In the steel structure’s reinforcement design, the load, bearing capacity, and joint properties of the steel structure must be considered. The bearing capacity of other steel components must be continuously adjusted and improved. Besides, it is necessary to continuously increase the maximum force of the entire steel structure building, and at the same time, fully consider the synergistic nature of the space steel structure, do a good job of strengthening the design of the steel structure, enhance the strength of the entire steel structure, and perform the strength according to the regulations—test inspection. If you want to increase the rigidity of the steel structure, you can increase the rigidity and load capacity of the entire steel structure by increasing the support points or natural vibration frequency to improve the stability of the steel structure. In the bent structure, the entire steel structure’s horizontal resistance can meet the actual demand by increasing the specific columns’ rigidity. The overall rigidity of the steel structure can be improved.
Component and joint design
To optimize the steel structure’s design, it is necessary to optimize the component’s cross-section to reduce the design cost of the steel structure. For complex steel structure building, each component’s cross-section must be checked strictly, especially the design of node modules, significant work in steel structure building design. In this process, it is necessary to analyze equal-strength design and actual stress issues. In the design, do a good job in welding, beam webs, and flanges. During node construction, the welding site must be strictly inspected. The bolts must be installed and tightened in strict accordance with relevant requirements so that each installation work can be carried out in an orderly manner.
In the design of steel structure building, corrosion resistance is the focus of the designer’s attention. Therefore, when engineers process the design, they must take corresponding measures for the construction site’s environment to prevent the steel building’s corrosion. The steel structure’s corrosion resistance can be improved by applying a material or coating with strong corrosion resistance to the steel structure to reduce the probability of corrosion of the steel structure. At present, the commonly used anti-corrosion material is anti-corrosion paint, and the specific usage amount of anti-corrosion paint is determined according to the actual construction situation; besides, semi-permanent or permanent coating methods are selected according to the maintenance method of the anti-corrosion design.
Fire protection design
Fire protection design is also the design focus of steel structure buildings. Therefore, materials with higher fire resistance and fire resistance must be used in the selection of materials. At present, in construction projects, it is necessary to select corresponding fireproof materials according to the building’s fireproof requirements and grades. When selecting materials, due to the thicker coating and higher viscosity materials, it has better fire resistance and fire resistance, so it is an excellent choice. However, in selecting flame-retardant materials for steel structures, if the thicker materials cannot meet the flame-retardant standards, relatively thin refractory materials can be selected at this stage, especially the flame-retardant and anti-rust treatments for the ceiling materials. In the fire protection design of steel structures, fire protection standards and protection grades are important reference standards, maximizing steel structures’ fire protection. Besides, the steel structure design should focus on stability and symmetry, avoid structural distortion in the design, and ensure the stability and continuity of the steel structure through through-through. In the steel structure building design, L-shaped or T-shaped design methods can ensure that the steel structure’s role is fully exerted. The structure’s location structures location is on the periphery of the structure. It can make the building’s anti-distortion and anti-deformation ability to reach optimal.
