In addition to the two significant fire protection and anti-corrosion issues, the essential thing for steel structure buildings is stability. In the design and construction of steel structures, stability issues are substantial. The stability of steel structure buildings mainly refers to the deformation of steel structures. If the steel structure loses its stability, dangerous situations such as bending or collapse of the building structure will occur, leading to substantial economic losses and potential safety hazards for personnel.
The instability of steel structures is mainly related to the design and construction of steel structure engineering. The key to stability design is to find a relatively balanced fit point in the unbalanced force to avoid a rather large deformation of the steel structure, which in turn causes the steel structure to instability and damage the building structure. Suppose the designer lacks experience in the design of steel structures and does not fully understand the instability of the steel structure. In that case, the problem of instability will appear in the design. In addition, failure to install according to regulations during construction or quality problems with materials are also important reasons for the instability of steel structures.
How to ensure the stability of steel structure buildings
1. Choose a professional structural engineer
Structural engineers should choose a professional and have many years of experience in the steel structure design. It is essential to distinguish the type of steel structure instability during the procedure to estimate the stability of the structure accurately. The instability types of steel structures include pivot instability, extreme point instability, and jump instability. Pivot instability: When the straight rod is axially compressed, and the surface of the plate is compressed, the pivot is instability. Extreme point instability: When building steel is used, it is made into structural parts under eccentric compression. However, when the plasticity of the structure continues to develop, it will become unstable to a certain extent. Jumping instability: There are no balance bifurcation points and extreme points, mainly to produce another stable equilibrium state after balance. Only by distinguishing the types of instability, in-depth research on the stability of the steel structure, mastering the design characteristics of the stability of the steel structure, and mastering the performance of each part can it be ensured that the problem of steel structure instability does not appear in the design.
2. Professional installers play an essential role in the stability of steel structure buildings
For steel structure installation, a professional installation team should be required for installation. The structural stability enhances the seismic performance and impact performance of the overall mechanism, and it is imperative to form an independent and stable structure during construction. The professional installation team has the experience and will check the installation components and install them in proper order according to the regulations.
3. The stability and safety of steel structure buildings also depend on steel quality.
The choice of steel must meet actual requirements, and the quality of processing and production must meet the specification requirements so that the installation of the plant structure will form an independent and stable structure, improve the seismic performance and impact resistance of the structure, and ensure the safety and stability of the overall structure.
4. Steel structure buildings cannot be modified or dismantled privately
Many steel-structured building collapse accidents are privately modified interior structures by the owners, causing structural instability and causing the overall building to collapse. Therefore, if the project needs to be retrofitted later, it must be communicated with the original construction unit and carried out after the design department confirms the safety.
5. Choose a professional steel structure manufacturer
Find a professional steel structure company team to work together to ensure the rationality of the design and the guarantee of the construction quality and avoid the hidden dangers caused by cutting corners and materials.
The stability of the steel structure relates to the safety of the entire building and cannot ignore. The basic principles that should be adhered to in the design of steel structure stability: In the process of steel structure design, the actual situation of the building and some specific requirements in the process of use should be comprehensively considered to ensure the designed steel structure the utmost extent. It can meet the standard well.
In the design process, the use of steel should be reduced to the greatest possible extent under the premise of satisfying stability and strength. The primary purpose of lowering steel is to reduce its weight so that the steel structure can have a good load-bearing capacity in the presence of a large load.
During the construction process, unnecessary installation practices and manufacturing practices should be minimized so that the steel structure can be better transported and maintained and effectively reduce the total cost. In addition, the steel structure designed should also have a specific aesthetic value.
