Shear Walls: Types, Functions, and Structural Advantages

What is a Shear Wall?

Shear wall is a structural member used to resist lateral forces, i.e., parallel to the plane of the wall. In other words, Shear walls are vertical elements of the horizontal force resisting system. Shear wall is a structural member in a reinforced concrete framed structure to resist lateral forces such as wind forces.

This is rarely practical since it also utilizes the space a lot, so they are positioned at the ends. It is better to use walls with no openings in them. So, usually, the walls around lift shafts and stairwells are used.

Classification of Shear Walls:

1. Column Supported Shear walls.

2. Core Type Shear Walls.

3. Rigid Frame Shear Walls.

4. Framed Walls with Infilled Frames.

5. Simple Rectangular Types and Flanged Walls.

6. Coupled Shear Walls.

 

7. Cantilever Shear Wall

Types of Shear Wall:

Here, the different types of shear wall are as follows.

1. Concrete Shear Wall
   • 
2. Steel Plate Shear Wall
   • 
3. Plywood Shear Wall
   • 
4. RHCBM (RC Hollow Concrete Wall Masonry.)
   • 

Functions of Shear Wall:

The main functions of a Shear Wall can be described as follows :

1. Strength to a building :
2. Stiffness to a building :

1. Strength to a building 

Shear Wall must provide lateral shear strength to the building to resist the horizontal earthquake forces, wind forces, and transfer these forces to the foundation.

2. Stiffness to a building 

Shear Walls provide large stiffness to building in the direction of their orientation, which reduces the lateral sway of the building and thus reduces damage to the structure.

Purpose of Shear Wall:

Here, the purpose of shear wall are as follows.

1. The verticle or gravity loads on the structure.
2. The counter shear and uplift forces.
3. The lateral loads of earthquakes and wind.
4. To make the structure more stable.

Advantages of Shear Wall

Here, the pr0s of shear wall are as follows.

1. These walls provide more strength, stability, and stiffness to a building.
2. Reduce lateral sway of a building.
3. Easy to construct and easily implemented at the site.
4. Thinner walls, hence lightweight.
5. Effective in minimizing earthquake damage in structural and non-structural elements.

Disadvantages of Shear Wall

Here, the cons of shear wall are as follows.

1. Shear walls are difficult to construct.
2. They have a flimsy appearance.
3. Also, loud banging sounds associated with the buckling of web plates.
4. It has low stiffness and energy dissipation capacity.
5. Also, requires large moment connections.
