Steel structures are becoming increasingly widely used. Their stability and lightweight have promoted the stability of the whole building. However, regarding the current situation, there are still some problems with their stability. Therefore, it is of great practical significance to strengthen the research on the stability of building steel structures.

Advantages of building steel structure:

High seismic resistance.

For construction projects, steel structures are selected because of their advantages. Due to the high strength of steel materials, it also has relatively strong plasticity and flexibility, which can meet the needs of construction projects. In addition, the elasticity of building steel structures is relatively good, and it has a high resistance to earthquakes. When an earthquake disaster occurs, the steel structure has a specific buffering capacity, and its seismic resistance increases the safety of the building;

The accuracy of the steel structure is high.

Materials with higher accuracy should be selected to enhance the stability of the building. The steel structure has such an advantage because it is more accurate than traditional reinforced concrete structures. In addition, steel structures also have a certain plasticity and toughness, which can be applied to large-span buildings. If you want to achieve the goal of enhancing the stability of the building, you should give priority to steel structure, which has a strong elasticity in stress amplitude, and this kind of steel building is in line with the mechanical calculation method of engineering construction under stress, and is widely used;

The construction process of building a steel structure is relatively simple.

Steel structures are mainly made of steel plates, cold-processed thin steel plates, or hot-rolled steel. The production process and method are relatively simple, shortening the construction period and cost.

Disadvantages of steel structure:

While building steel structures has certain advantages, it also has certain shortcomings, mainly reflected in the relatively poor corrosion and fire resistance of steel structures. These all hide certain dangers and are prone to accidents. In addition, in the construction process, low-strength components are usually selected, which limits the overall stability of the building. Because the construction unit pays attention to stability but ignores the importance of strength, it wastes building materials and hurts the quality of the construction project.

Principles of stability of building steel structure:

Ensure stability in all aspects.

In the design process of steel structures, to ensure their stability, it is necessary to consider this issue from a global perspective, set up an overall stability structure, and then provide the stability of each layout in the steel structure. Because the parts and the whole are interdependent, ensuring the strength of the components is to lay a good foundation for overall stability.

Shear force adjustment problem.

The shear force adjustment problem is one of the critical issues in the stability design of steel structures. With the improvement of the national economic level, the forms of buildings are diverse, and the frequency of inclined columns or asymmetrical building forms is high, which puts higher requirements on the stability of structures. Simplifying the vertical components into columns and the inclined components into slashes has a specific promoting effect on the design of buildings. Still, it will have a particular impact on the shear force adjustment. Therefore, the adjustment of the shear force problem is done to the best, and the overall stability of the steel structure design can be achieved;

Design of solid columns and weak beams.

Solid columns and weak beams can be adopted to promote the stability of steel structures. This design is necessary when the steel structure is facing a large load. The plastic hinge needs to appear on the beam instead of the column, which can effectively ensure the overall stability of the steel structure and will not cause instantaneous damage. In addition, the accuracy and scientificity of the substantial column and weak beam design should be guaranteed according to the relevant national standards and specifications.

Factors affecting the stability of building steel structures:

On the one hand, it depends on the relationship between the overall stiffness and the steel structure because the overall process of the steel structure determines the stiffness of the steel structure;

Second, the qualitative nature of the building steel structure is related to its internal components. In the process of construction, effectively grasp the concept of integrity, pay attention to the situation at all levels of the steel structure, and ensure the overall stability of the building steel structure; in addition, pay close attention to some issues related to the steel structure and take active countermeasures.

Issues that should be noted in the design process of the stability of building steel structures:

In the design process of the stability of building steel structures, do not focus on a single design idea but fully consider the specific conditions of the construction. Due to the diversity of current building forms and the different number of floors of buildings, the requirements for building steel structures are also very different. Symmetrical designs are used to enhance the overall stability of steel-structure buildings. In this way, when earthquake disasters come, due to their strong seismic resistance, they can effectively reduce the risk of earthquake disasters and reduce property and personnel damage.

Steel structures must meet specific standards for stability and strength, and perfect components with super stability must be designed. Suppose the stability of steel components is damaged during construction. In that case, timely measures must be taken to enhance the overall bearing capacity of building components through the buckling strength of steel components.

In addition, new technology can calculate the stability of building steel structures to solve complex problems in building construction. Due to computers’ intelligence and high efficiency, the accuracy and speed of calculations are increased, which helps with the stability of building steel structures.
