IS 456 : 2000 Plain and Reinforced Concrete - Code of Practice

1 Scope

1.1 This standard deals with the general structural use of plainand reinforced concrete.

1.1.1 For the purpose of this standard, plain concretestructures are those where reinforcement, if provided is ignoredfor determination of strength of the structure.

1.2 Special requirements of structures, such as shells, foldedplates, arches, bridges, chimneys, blast resistant structures,hydraulic structures, liquid retaining structures and earthquakeresistant structures, covered in respective standards have not beencovered in this standard; these standards shall be used inconjunction with this standard.
