　　First, according to the application of steel structure can be divided into building engineering, bridge engineering, hydraulic engineering, marine engineering, special engineering, etc.. Steel structures used in different fields are often referred to as the steel structures in the field, such as: building steel structure, bridge steel structure, etc..

Second, the classification of steel structure according to the specifications used. One is the light steel structure, steel structure of 1.5 mm ~6 mm thickness steel plates and small round steel, steel structure; two is the ordinary steel structure: steel structure 8 mm ~40 mm thick steel plate and a common type of steel structure; three is a heavy-duty steel structure: steel structure is greater than 40 mm thickness steel plate and special steel.. The steel structure made of steel plate with thickness less than 1.5 mm can also be called super light steel structure.
The processing, fabrication, installation and mechanical performance and failure characteristics of the steel structures of different specifications are different. The stability and sensitivity of the light steel structure are more prominent. The effects of welding and installing residual stresses on the lamellar tearing, fatigue and brittle fracture of the steel structure can not be ignored.
