1 General
1.0.1 This code was formulated with a view to implementing the national technical and economic policies in the design of concrete structures, achieving safety, applicability and economy and guaranteeing quality.
1.0.2 This code is applicable to the design of buildings and other general structures made by reinforced concrete, prestressed concrete and plain concrete. But it is not applicable to the design of structures using light self-weight aggregate concrete and special concrete.
1.0.3 This code was formulated based on the principle of the current national standards “Unified Standard for Reliability Design of Engineering Structures” (GB 50153) and “Unified Standard Reliability Design of Building Structures” (GB 50068). This code gives the basic requirements for the design of concrete structures.
1.0.4 In addition to this code, the design of concrete structures shall also comply with those stipulations specified in the relevant current national standards.
