Why do long-span steel structure projects need reinforcement
When we have not been exposed to the steel structure industry, we must not know much about it. But for professionals, they must know the reason. The same is true for steel structure space frame , so why should large-span steel structure projects be reinforced? 1. Changes in process operations cause changes in the structural layout and stress conditions of steel structures; 2. The increase of load (such as adding insulation layer to the roof of steel structure buildings, increasing the lifting capacity of cranes in steel structure workshops, or adding cranes to workshops without cranes, etc.); 3. Accidental damage, such as war damage, damage caused by natural disasters (such as earthquakes); 4. Various defects due to poor design consideration or design errors, as well as construction quality accidents of steel structure buildings. For example, the design of the truss gusset plate does not consider the construction assembly error, resulting in insufficient length of the welding s
