  Steel structures are primarily composed of steel components, characterized by steel beams, steel plates, steel columns, steel trusses, and other elements; they are a major type of building structure, connected through welding, bolts, or rivets between each member or component. When damage occurs in a steel structure, it should be identified and addressed immediately. (1) Insufficient load-bearing capacity due to changes in load, overtime work, or revisions to standards and regulations; (2) Deformation, distortion, loss of functionality, or indentation of components caused by various accidents, leading to weakened cross-sections, warped members, or cracked connections; (3) Deformation, cracking, or warping of components or connections caused by temperature differences; (4) Corrosion and electrochemical corrosion caused by chemical erosion, weakening the cross-section of steel structure components; (5) Other issues including errors in design, production, or construction, as well a...

  1. Definition of Snow Load Snow load refers to the calculated snow pressure acting on the roof surfaces of buildings or structures, typically representing a spontaneous meteorological load formed by accumulated snow. The magnitude of snow load primarily depends on regional snowfall amounts derived from meteorological data, roof configurations, building geometric dimensions, and normal building usage conditions. In short, snow load is a critical factor in architectural design to ensure structural safety and stability under snow accumulation conditions. 2. Factors Affecting Snow Load Snow load significantly impacts building design across different regions, primarily through the following aspects: (1) Geographic Location and Climate Conditions: Snow load levels vary by region, requiring design parameters to be determined based on local climate and topography. For instance, high-altitude areas and mountainous regions typically experience heavier snow loads, while low-altitude areas a...

  In the current rapid development of social construction, bolt ball grids are used in many large-scale engineering construction processes. Steel structure buildings are used in many large shopping malls, office buildings, and cold storage warehouses. The steel structure of the factory is divided into light steel structure factory and heavy steel structure factory. Bolt ball grid plays an important role. So, what are the advantages of bolt ball grid? In the construction process of many large office buildings, the bolt ball grid is light in weight, has strong plasticity, uses high-strength steel, has a large span of manufacturing plant, and can be made into a structure with a large span. The bolt ball node of the grid is realized by connecting the rod and the ball through high-strength bolts. It is easy to install on site, which can greatly shorten the construction period and improve construction efficiency. In addition, the advantage of the bolt ball node of the grid is that it ha...
