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 the construction of steel building projects, it is necessary to continuously optimize the steel structure building design and increase the strength to improve steel buildings’ stability and quality.
Steel structure building design
The main component of a steel structure building is steel, and the steel structure is relatively uniform.
At present, low corrosion resistance, heat and fire resistance of steel structures have effectively improved. The application range of steel has also increased. The main component of steel structure design is bolt connection. The key is to apply mechanics to scientifically handle the relationship between each component’s arms and moments and to connect each node effectively reasonably.
The focus of steel structure building design
Reinforce design of steel structure
In the steel structure’s reinforcement design, we must consider the steel structure’s load, bearing capacity, and joints. The bearing capacity of steel components must be continuously adjusted and improved.
Suppose you want to increase the strength of the steel structure. In that case, you can increase the entire steel structure’s load capacity by expanding the support points or natural vibration frequency to improve the steel structure’s stability. In the frame structure, the horizontal resistance of the entire steel structure can meet actual needs by increasing columns’ rigidity and improving the steel structure’s overall strength.
Component and joint design
It is necessary to optimize the cross-section of the component to reduce the cost of the steel structure. For steel structures with high complexity, each component’s cross-section must strictly check, especially the nodes’ design, significant in the steel structure building design. In this process, strength design and stress issues need to be analyzed. In the fabrication, do an excellent job in the welding, beam webs and flanges, and other plates. During node connection, we must strictly inspect the welding, and the bolts must be installed and tightened following the relevant requirements so that we can carry out the installation work smoothly.
In steel structure building design, corrosion resistance is the focus of the designer’s attention. Therefore, when engineers design the steel building kits, they must take corresponding measures to prevent the steel structure’s corrosion according to the construction site’s environment. Applying a material or coating with strong corrosion resistance on the steel structure can improve the steel structure’s corrosion resistance. At present, the commonly used anti-corrosion material is paint. Besides, according to the maintenance method of the anti-corrosion select semi-permanent or permanent coating methods.
Critical points of fire protection design
Fire protection design is also the focus of steel structure building design. Therefore, we must use materials with higher fire resistance and fire resistance. At present, in construction projects, it is necessary to select corresponding fireproof materials according to the building’s fireproof requirements and grades.
When choosing materials, due to the thicker coating and higher viscosity of the material, fire resistance and fire resistance are better, so it is a perfect choice.
In the fire protection design of steel structures, fire protection standards and protection levels are necessary reference standards, maximizing steel structures’ fire protection level. Besides, the steel structure building design should focus on stability and symmetry, avoid structural distortion in the design, and ensure the steel structure’s stability and continuity through up and down penetration in the steel structure design.
