IS 456: 2000 RC Col and Footing Design



IS 456:2000 is a code of practice published by the Bureau of Indian Standards (BIS) for the design and construction of reinforced concrete (RC) structures in India. This code provides guidelines and standards for various aspects of RC construction, including design principles, materials, and construction practices.

When it comes to designing RC columns and footings, IS 456:2000 outlines the following key points:

  1. Material Properties:

    • Specifies the properties of concrete and reinforcement materials to be used in construction.
    • Defines grades of concrete and steel reinforcement along with their respective strengths.
  2. Design Principles:

    • Provides principles for structural design, including load considerations, safety factors, and methods for determining the dimensions of structural members.
    • Emphasizes on ensuring safety and durability of structures under various loading conditions.
  3. Column Design:

    • Gives guidelines for designing RC columns based on factors like axial loads, moments, and lateral forces.
    • Specifies minimum dimensions, reinforcement requirements, and detailing provisions to ensure adequate strength and stability of columns.
  4. Footing Design:

    • Covers the design of footings, which are structural elements that support the loads from columns and transfer them to the soil.
    • Provides methods for determining the size and depth of footings based on the applied loads and soil bearing capacity.
    • Includes provisions for different types of footings such as isolated footings, combined footings, and raft footings.
  5. Reinforcement Detailing:

    • Prescribes detailing requirements for reinforcement in RC columns and footings to ensure proper anchorage, distribution of forces, and prevention of structural failure.
  6. Construction Practices:

    • Offers recommendations for construction practices to ensure quality and durability of RC structures.
    • Covers aspects such as concrete mixing, placement, compaction, curing, and quality control of materials.

Overall, IS 456:2000 serves as a comprehensive guide for the design and construction of RC columns and footings, helping engineers and construction professionals ensure the safety, durability, and performance of reinforced concrete structures in India.
