What is IS 456 Code?
IS 456 code is an Indian Standard code of practice for general structural use of plain and reinforced concrete. It covers the design, construction, and maintenance of concrete structures for buildings, bridges, dams, and other civil engineering works. It is one of the most widely used codes in India and abroad.

Definition and Scope
According to IS 456 code, plain concrete is concrete without any reinforcement or prestressing. Reinforced concrete is concrete with reinforcement embedded in it in such a manner that the two materials act together in resisting forces. Prestressed concrete is concrete in which internal stresses are introduced by applying forces to tendons before or after hardening of concrete.
The code applies to both plain and reinforced concrete structures made with ordinary Portland cement or blended cements. It does not cover prestressed concrete structures or special types of concrete such as light-weight concrete, heavy-weight concrete, no-fines concrete, etc.
History and Revisions
The first edition of IS 456 code was published in 1953. It was based on the British code CP 114. The second edition was published in 1964. It was based on the British code CP 110. The third edition was published in 1978. It introduced the limit state design method as an alternative to the working stress design method. The fourth edition was published in 2000. It incorporated several amendments and revisions based on the latest research and developments in concrete technology. The latest revision of this standard was done in the year 2019. It included some changes in the clauses related to materials, durability, design, detailing, etc.

Importance and Applications
IS 456 code is important because it provides a comprehensive and uniform set of guidelines for the design, construction, and maintenance of concrete structures in India and abroad. It ensures the safety, serviceability, durability, and economy of concrete structures. It also promotes the use of good quality materials, workmanship, inspection, and testing. IS 456 code is applicable to a wide range of concrete structures for various purposes. Some of the common applications are: - Buildings: residential, commercial, industrial, institutional, etc. - Bridges: road, rail, pedestrian, etc. - Dams: gravity, arch, buttress, etc. - Water tanks: overhead, underground, etc. - Retaining walls: cantilever, counterfort, etc. - Foundations: shallow, deep, pile, etc. - Pavements: rigid, flexible, etc. What are the Main Features of IS 456 Code 2019?
IS 456 code 2019 has several features that make it a comprehensive and updated code of practice for concrete structures. Some of the main features are:
Materials, Workmanship, Inspection and Testing
The code specifies the requirements and standards for various materials used in concrete structures such as cement, aggregates, water, admixtures, reinforcement, etc. It also provides guidance on the selection and proportioning of concrete mixes based on the exposure conditions and strength requirements. It also covers the aspects of workmanship such as batching, mixing, transporting, placing, compacting, curing, etc. It also lays down the criteria and methods for inspection and testing of concrete structures such as sampling, testing frequency, acceptance criteria, etc.
General Design Considerations
The code outlines the general principles and assumptions for the design of concrete structures such as loads and load combinations, structural analysis methods, limit states and design values, partial safety factors, serviceability requirements, durability requirements, fire resistance requirements, etc. It also gives guidance on the design of special structures such as arches, shells, folded plates, etc.
Structural Design (Limit State Method)
The code presents the limit state design method as the preferred method for the structural design of concrete structures. The limit state design method is based on the concept of limiting the stresses and deformations in the structure to acceptable levels under various load conditions. The code covers the design of various structural elements such as beams, slabs, columns, footings, walls, stairs, etc. using the limit state design method. It also provides the design charts, tables, and formulae for the calculation of the design values of various parameters such as bending moment, shear force, deflection, crack width, etc.
Structural Design (Working Stress Method)
The code also presents the working stress design method as an alternative method for the structural design of concrete structures. The working stress design method is based on the concept of ensuring that the stresses in the structure do not exceed the permissible values under various load conditions. The code covers the design of various structural elements such as beams, slabs, columns, footings, walls, stairs, etc. using the working stress design method. It also provides the design charts, tables, and formulae for the calculation of the permissible stresses and other parameters.
Special Design Requirements for Structural Members and Systems
The code also addresses the special design requirements for some structural members and systems such as deep beams, corbels, flat slabs, prestressed concrete members, composite construction, etc. It also gives guidance on the design of structures subjected to dynamic loads such as wind, earthquake, blast, etc.
Ductile Detailing of Reinforced Concrete Structures Subjected to Seismic Forces
The code also provides the provisions for the ductile detailing of reinforced concrete structures subjected to seismic force
