Steel Standards for Steel Structures and Industrial Standards

The principle of material selection for steel structures is to ensure the bearing capacity of the load-bearing structure and to prevent brittle failure under certain conditions. Considering the importance of the structure, load characteristics, structural form, stress state, connection method, steel thickness and work environment, etc. of.

The four types of steel products proposed in the “Code for Design of Steel Structures” GB50017-2003 is a model suitable for use. It is the first choice when the conditions permit, and it does not prohibit the use of other models, as long as the steel used meets the requirements of the specification. .

For a more detailed explanation of the selection of steel structure materials, see the “Texture of Steel Structure Design” GB 50017-2003 description, where the explanation is very specific.

The application of steel structures in construction projects has become increasingly widespread and has developed rapidly. As the standard of steel structure for controlling and guaranteeing the quality of engineering, more and more attention has been paid to the engineering community.
