1.0.1 This code intends to implement the technical-economic policy of the State in the design of steel structures, by using advanced technology and ensuring economy, reasonableness, safety, suitability for use and good quality of the structures.
1.0.2 This code applies to the design of steel structures of industrial and civil buildings and allied engineering structures, among which members made of cold-formed steel shapes and their connections shall comply with the current national standard “Technical Code of Cold-formed Thin-wall Steel Structures” GB 50018.
1.0.3 The design principles of this code are based on the “Unified Standard for Reliability Design of Building Structures” GB 50068. Loadings and their combination values assumed in designing with this code shall comply with the current national standard “Load Code for the Design of Building Structures” GB 50009. Buildings and engineering structures in seismic region shall furthermore comply with the current national standards “Code for Seismic Design of Buildings” GB 50011, “Seismic Ground Motion Parameter Zonation Map of China” GB 18306 and “Design Code for Antiseismic of Special Structures” GB 50191.
1.0.4 In designing steel structures, designers shall consider the real situation of the project, select reasonably the material, the structural scheme and detailing measures. The requirements of strength, stability and stiffness of the structure during transportation, erection and service, as well as requirements of fire protection and corrosion resistance shall be fulfilled. Typical and standardized structures and structural members should he adopted in preference, the amount of fabrication and erection work should be reduced.
1.0.5 In the design documents of steel structures shall be indicated the design working life of the building structures, the steel grade, the category (or grade) of connection materials and mechanical properties, chemical composition and additional items of guarantee of the steel. Moreover, the weld type and the class of weld quality, the location of end planning for close fitting and its quality requirement shall also be indicated.
1.0.6 The design of steel structures with special requirements and those under special circumstances shall furthermore comply with the relevant current national codes.
