Principles and Key Factors of Overall Stability Design for Architectural Steel Structures

Principles of Overall Stability in Architectural Steel structures: 

(1) Ensuring stability in all aspects. In the design process of steel structures, in order to ensure the overall stability of buildings, it is necessary to consider this issue with 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, ensuring the stability of components lays the foundation for the overall stability; 

(2) Shear adjustment issues. Shear adjustment is one of the important issues in the stability design of steel structures. With the improvement of the country's economic level, various forms of buildings have appeared more frequently, and the frequency of inclined columns or asymmetric building forms is higher, which puts higher requirements on the stability of buildings. Simplifying vertical components into columns and inclined components into diagonal braces has a certain promoting effect on the design of buildings, but it will have a certain impact on shear adjustment. Therefore, doing the best job in shear adjustment can achieve the overall stability of steel structure design;

 (3) Strong column weak beam design. In order to promote the overall stability of architectural steel structures, the design concept of strong column weak beam can be adopted. The reason for this design is that when steel structures are faced with larger loads, plastic hinges need to appear on beams rather than columns. This can effectively ensure the overall stability of steel structures and prevent instantaneous damage. In addition, it is necessary to ensure the accuracy and scientificity of the design of strong column weak beam according to national relevant standards and regulations. 

  Factors Affecting the Overall Stability Design of Architectural Steel Structures: On the one hand, it depends on the relationship between overall stiffness and steel structures, because the stiffness of steel structures is determined by the overall process of steel structures; secondly, the overall stability of steel structures is related to internal components of steel structures. In the construction process of buildings, grasping the concept of integrity effectively and paying practical attention to various aspects of steel structures to ensure the overall stability of architectural steel structures; in addition, it is also necessary to pay close attention to some issues related to steel structures and take proactive measures.

  Issues to Note in the Overall Stability Design of Architectural Steel Structures: In the process of overall stability design of architectural steel structures, do not stick to a single design idea, and fully consider the specific conditions of construction. Due to the diversity of architectural forms and the different number of floors, the requirements for architectural steel structures are also very different. In the construction of steel structures, in order to enhance its overall stability, try to choose symmetrical design, so that when earthquake disasters come, due to its strong earthquake resistance, it effectively reduces the danger of earthquake disasters and reduces property and personnel damage.
