The concept of stability of building steel structures

The strength of the building steel structure is not enough, or the instability phenomenon appears, will have a certain impact on the building structure. The stability and strength of the building steel structure are different, because the building components are subjected to the external load and the internal resistance of the building structure, there is instability during this period, in the process of construction, the most important task is to find a balanced state, so as to reduce the phenomenon of steel structure damage. In the building construction process, the strength of steel is high, in the case of pressure, in order to find a balance between strength and stability, to achieve the best effect, often choose the stability requirements, which leads to the strength of the building steel structure is not well played. It can be seen that in the design process of building steel structure, we should pay attention to the definition of steel structure strength and stability, and fully understand the important factors that cause damage to the building.

Principles for the overall stability of building steel structures

• Ensure stability in all aspects. In the design process of steel structure, in order to ensure the overall stability of the building, we must consider this problem from a global perspective, set up an overall stability structure, and then ensure the stability of each layout in the steel structure, because the part and the whole are interdependent, so to ensure the stability of the components is to lay a good foundation for the overall stability;
• Shear adjustment problem. The problem of shear adjustment is one of the important problems in the stability design of steel structure, because with the improvement of the national economic level, the forms of buildings are diverse, and the frequency of inclined columns or asymmetric building forms is higher, which puts forward higher requirements for the stability of buildings. The vertical members are simplified into columns and the inclined members are simplified into slashes. This simplification has a certain promotion effect on the design of the building, but it will cause certain impact on the adjustment of the shear force. Therefore, the adjustment of the shear force problem can achieve the overall stability of the steel structure design.

 Design of strong column and weak beam. In order to promote the overall stability of the building steel structure, the design concept of strong column and weak beam can be adopted. The reason for this design is that when the steel structure is faced with a large load, the plastic hinge needs to appear on the beam rather than the column, which can effectively ensure the overall stability of the steel structure, and there will be no instantaneous damage. In addition, according to the relevant national standards and norms, to ensure the accuracy and scientific design of strong columns and weak beams.

Factors affecting the overall stability design of building steel structure

The factors that affect the overall stability of the building steel structure depend on the relationship between the overall stiffness and the steel structure, because the stiffness of the steel structure is determined by the overall process of the steel structure; Secondly, the overall stability of the steel structure has a certain connection with the internal components of the steel structure. In the construction process, the overall stability of the steel structure is ensured by effectively grasping the holistic concept and paying attention to the situation at all levels of the steel structure. In addition, we should pay close attention to some problems related to steel structure and take positive countermeasures.

Attention should be paid to the overall stability design of building steel structure

In the design process of the overall stability of the building steel structure, do not stay on a single design idea, and fully consider the specific situation of the building construction. Due to the diversity of building forms, the number of floors of the building is different, so the requirements of the building steel structure are also very different, in the steel structure of the building, in order to enhance its overall stability, as far as possible to choose a symmetrical design, so that when the earthquake disaster comes, because of its strong earthquake resistance, effectively reduce the risk of earthquake disasters, reduce property and personnel damage.

The stability and strength of the building steel structure should reach a certain standard, and the design of the perfect super stability of the components. If the stability of the steel components is found to be damaged during the construction process, timely measures should be taken to enhance the overall bearing capacity of the building components through the buckling strength of the steel components.
