walls

Introduction to Walls

  • Definition: Structural elements of a building used for partitioning, providing safety and shelter.

  • Classification:

    • Outer walls: Provide enclosure for rooms.

    • Inner walls: Internal partitions.

Types of Walls

  • Classification Based on Function:

    1. Load Bearing Wall

    2. Non-Load Bearing Wall (Drop Wall)

    3. Shear Wall

    4. Retaining Wall

    5. Brick Masonry Wall

    6. Stone Masonry Wall

    7. Core Wall

    8. Precast Wall

    9. Parapet Wall

    10. Curtain Wall

    11. Boundary Wall

Detailed Types of Walls

Load Bearing Wall

  • Function: Supports the structure instead of columns.

  • Load Transfer: From the slab to the walls directly via beams.

  • Foundation: Typically has a strip foundation.

Non-Load Bearing Wall

  • Definition: Does not support any structural loads above.

  • Examples: Partition walls; can be removed without affecting the building structure.

Shear Wall

  • Function: Built to withstand lateral forces such as wind and earthquakes.

  • Applications: Commonly around lift pits, water sumps, and staircases.

  • Example: Used to resist pressures in overhead water tanks due to wind and internal water pressure.

Retaining Wall

  • Purpose: Maintains soil levels on either side of the wall.

  • Construction Materials: Can be made of Reinforced Cement Concrete (RCC) or Concrete Reinforced Stone (CRS).

  • Types: Gravity retaining walls and brick masonry.

Brick Masonry Wall

  • Construction: Made using bricks, with masonry used to bind them.

  • Thickness: Usually between 10cm to 20cm.

  • Height Limit: Should not exceed 4m in a single stretch without an RCC column.

Stone Masonry Wall

  • Definition: Constructed using stones.

  • Common Uses: Abutments of bridges, compound walls, and boundary walls.

Core Wall

  • Definition: Extends from the foundation to the top of a building.

  • Functionality: Acts as both a wall and a column to resist lateral forces.

  • Relation to Shear Walls: A combination of shear wall functionality.

Precast Wall

  • Characteristics: Factory-made walls that are transported to the construction site.

  • Specifications: Length and height need to be specified before casting.

Parapet Wall

  • Location: Constructed on the roof of the building.

  • Height: Typically around 3 feet.

Curtain Wall

  • Materials: Made of glass, aluminum, or steel frames.

  • Usage: Common in offices, hospitals, and public buildings.

Boundary Wall

  • Purpose: Encloses the entire plot.

  • Function: Establishes limits of the property and provides security.
