 1. Rust on steel structures can be divided into three types: ① Light rust: Pitting corrosion appears on the surface, and some parts develop oxide scale. ② Moderate rust: Bright red rust spots and some oxide scale cracks. ③ Heavy rust: Oxide scale peels off, and the oxide layer increases. Some thick oxide layers can cause the steel structure surface to sink. 2. The main hazards caused by rust on steel structures: ① Stainless steel structures will have reduced load-bearing capacity and affect structural stability. ② Stainless steel structures will increase maintenance costs. ③ Rust on steel structures will shorten their service life. If steel structures are not regularly maintained and treated in a timely manner, rust stains and oxide scale will increase the corrosion and rust rate of the steel structure, which will not only affect the service life of the steel structure but also create potential safety hazards. 3. Effective methods for dismantling steel structures: ① Manual rust r...

  The cross-sections of steel space frame components should be determined based on compressive strength and reliability calculations. To reduce the calculated length of compression members and improve reliability, measures such as adding sub-compression members and support frames can be adopted.   The connection points of plate-shaped spherical space structures   and two-shell spherical space structures   made of stainless steel mainly include cross-plate connection points, welded hollow sphere connection points, and anchor bolt sphere connection points. Cross-plate connection points are suitable for steel space structures   with channel steel components; the connection between the component and the connection plate is achieved by welding or high-strength bolts. Hollow sphere connection points and anchor bolt sphere connection points are suitable for steel space structures   with seamless steel pipe components. The connection points of single-shell spheric...
