What are the main causes of damage to steel structures?

图片
  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...

Maintenance Tips for Grid Roofs After Operation

  1. Do not place heavy objects on any part of the grid roof. Because grid structures are designed based on the required loads, the specifications of the members and joints are determined based on the specified design loads. Therefore, placing heavy objects exceeding the design requirements during operation is strictly prohibited. This will cause irreversible damage to the grid structure. 2. Regularly perform corrosion protection during operation. The general design life of grid structures is 50 years. Damage from excessive loads during operation is rare. Most damage is caused by rust, which significantly reduces the cross-section of grid members and significantly reduces their mechanical and physical properties. 3.The exterior paint protection of the grid structure must meet the requirements of its operation.  Generally, maintenance is required every three years. Clean the surface of dust, rust, and other contaminants before repainting. Maintenance Methods for Grid Coatings:...
