1 General Provisions
1.0.1 This specification is formulated with a view to implementing the national technical and economic policies, achieving safety and usability, advanced technology and economic rationality and ensuring quality in the design and construction of concrete structures with specially shaped columns.
1.0.2 This specification is primarily applicable to the design and construction of concrete structures with specially shaped columns in such ordinary residential buildings of non-seismic design or of seismic design with seismic fortification intensity 6, 7 (0.10g, 0.15g) and 8 (0.20g).
1.0.3 In addition to this specification, the design and construction of concrete structures with specially shaped columns shall also comply with those specified in the current relevant standards of the nation.
