Chapter 1 General
1.0.1 This Specification is formulated with a view to implementing the national technical and economic policies in the design and construction of concrete-filled steel tubular structures to be of advanced technology, economy and rationality, safety and usability.
1.0.2 This Specification is applicable to the design and construction of concrete-filled steel tubular structures for industrial and civil buildings and structures. The steel tube concrete in this Specification refers to the concrete-filled steel tubular structures of circular steel tube filled with concrete.
1.0.3 This Specification is formulated based on the principle specified in the national standard "Unified standards for the design of structure" (GBJ68-84). The symbols, measurement units and basic terms are adopted according to the requirements of national standard "Design of structures-general symbols units of measurement and basic terms" (GBJ 83-85).
1.0.4 When designing and constructing according to this Specification, in addition to the definite requirements of this Specification, the loading shall be implemented according to the requirements of "Load Code for the Design of Building Structures " (GBJ 9-87), the design shall also meet the requirements of the national standards "Code for Design of Steel Structures" (GBJ17-88), "Code for Design of Concrete Structures " (GBJ 10-89) and "Code for Seismic Design of Buildings" (GBJ 11- 89); the quality of material and construction shall also meet the requirements of the national standards " Code for Construction and Acceptance of Steel Structure Engineering "(GBJ 205-83 and "Code for Construction and Acceptance of Concrete Structures" (GBJ 204-83).
1.0.5 The surface temperature of concrete-filled steel tubular structure should not exceed 100℃; where it exceeds 100℃, effective shall be taken.
1.0.6 As for the structure with fire prevention and corrosion protection requirements, and corrosion protection treatments shall be carried out according to relevant special requirements.
