It covers the minimum requirements for the design, materials, construction and quality of RCC structures.
The design of RCC structures involves a number of calculations and analysis to ensure the safety, stability, and durability of the structure. The main analysis that are performed in the design of RCC structures as per IS 456 are:
Load Calculation: The loads that the structure will be subjected to, such as dead load, live load, wind load, and earthquake load, must be calculated and considered in the design.
Flexural Analysis: This analysis determines the maximum bending moment and shear force in beams and slabs, which is used to design the reinforcement.
Column Analysis: The column analysis is used to determine the compressive force and the maximum bending moment in columns, which is used to design the reinforcement.
Shear Analysis: This analysis determines the maximum shear force in beams and slabs, which is used to design the shear reinforcement.
Torsion Analysis: This analysis is used to determine the maximum torsional moment in reinforced concrete members, which is used to design the torsion reinforcement.
Bond and Development Length Analysis: This analysis is used to determine the bond strength and development length of the reinforcement in concrete members, which is used to design the reinforcement.
Durability Analysis: This analysis is used to determine the durability of the structure, in terms of the protection against corrosion and the service life of the structure.
Seismic Analysis: This analysis is used to determine the seismic forces and design the structure as per the seismic zone.
By following the guidelines set forth in IS 456 and performing the above-mentioned analysis, structural engineers can ensure that their RCC structures are safe, stable, and will perform well over time.
