All About Adding Columns in Compound Walls

A compound wall is a contemporary styled design that splits an area of land into two. A compound wall is constructed with cement and bricks. These will sink into the ground to the places where the soil capacity is very poor. 

Compound walls have columns added which will help transfer loads from the ceiling. So a column or a pillar is an architectural design that provides support for the wall. Let’s learn everything about the columns including types of columns based on different aspects, reasons why columns are added and the technical aspects while construction.

Types of Columns in Construction

Columns are classified based on the types of reinforcement, types of loading, slenderness ratio, shape.

Based on the types of reinforcement, the columns have been classified into:

  1. Tied column: In tied columns, the longitudinal reinforcement bars are tied together. As per the calculation, 95% of compound walls are tied.
  2. Spiral column: Spiral columns are shaped spirally and it can bear more loads than tied columns.
  3. Composite column: It is a combination of structural steel and structural concrete. Composite columns have high tensile strength.

Based on the types of loading, the columns have been classified into:

  1. Axially Loaded column: These are columns subjected to loads acting along the longitudinal axis or centroid of the column section.
  2. Uniaxial eccentric loading: A uni-axial eccentrically loaded column is such a column in which the incoming axial load is not on the axis of symmetry along one of axis.
  3. Biaxial eccentric loading: If the eccentricity is under both the axis then it is said to be under biaxial columns.

Based on the slenderness ratio, the columns have been classified into:

  1. Short column: When the lateral dimension of a column is very small compared to its length, then it is said to be a short column.
  2. Long column: When the lateral dimension of a column is very large compared to its length, then it is said to be a long column.

Based on the shape, the columns have been classified into:

  1. Square columns:  Square columns are the easiest columns to be constructed than all other columns. 
  2. L shaped columns: These are mainly placed on the corners of the boundary walls. They have similar properties like square columns.
  3. T shaped columns: They are constructed in the shape of letter T which is most commonly used in the construction of bridges.
  4. Circular columns: In this case, the columns are designed in a circular shape which is used for piling and elevation of buildings.
  5. Shape of Composite Columns: Composite columns are designed to describe column design. 

Based on construction materials, the columns have been classified into:

  1. Reinforced concrete: Reinforced concrete provide reinforcement with the use of embedded steels.
  2. Steel column: They have high compressive strength and has the ability to bend under extreme load arrival.
  3. Timber: Timber columns are most commonly used in house buildings, reception areas, etc. They will provide a feeling of openness and space. 
  4. Brick: Brick columns will provide strength to the buildings makes it look beautiful.
  5. Stone Column: It is very easy to construct and can be constructed at any time in the year.

Why Columns in Compound Walls?

Columns used in the compound wall will provide lateral stability against overturning. Columns will avoid signposts and display boards. For long walls, twin columns are used which helps to avoid cracks from developing. When the wall is affected with lateral load, then no more joints will be capable to sustain the tensile strength, so in these cases, columns must be provided immediately.

If the compound walls are very much longer then you should provide columns for their support.

Distance between two consecutive columns in a compound wall?

The distance between two consecutive columns in a compound wall totally depends on the height and width of your compound wall. The distance can be changed depending on the column size and structure. The size of the column depends on the total amount of load provided for the column. The minimum size of the column should be about 9”*9”. These 9”*9” sized columns are used for the single-story structure. Make sure that the distance between the two columns must be equal between the centers of the two columns. The distance of two 9”*9” columns should not be about 4m center to center of the column.

Depending on the type of column used, the distance between columns can be measured. Wood columns can be constructed several meters in diameter and 60 feet or more. In the case of steel column, columns are either I-beams, round pipe, or square tubing, and using high strength steel, can be very tall and large.

The compound wall with columns will protect the buildings when compared to other compound walls does. Columns are great add-ons to provide strength too. For any queries about columns, please drop your comments in the comment box.
