# HOW TO CLASSIFY WALLS IN A BUILDING? [BASED ON FUNCTION]

Walls are built to divide the living area into different parts. They provide privacy and protection against temperature, rain and theft. Walls can be classified into the following two primary classes on the basis of their functions:

2. partition walls.

If beams and columns are not used, the load from the roof and floor is transferred by the walls to the foundation. Such walls are called load bearing walls. They have to be designed to move the load safely. The significant part of the walls is near the openings of doors and windows and the places where the concrete beams rest.

The minimum wall thickness used is 200 mm. It is also recommended that the thinness ratio of the wall defined as the ratio of thickness to effective length or effective height should not exceed 27. The effective height and effective length of the wall can be taken as shown in Table-1 and 2 respectively.

 Table 1 [Effective height of walls in terms of actual height H] Last position effective height Lateral as well as rotational restraint 0.75 h Lateral as well as rotational restraint at one end and only lateral restraint at the other 0.85 h Lateral restraint but no rotational restraint at both ends 1.0 h Lateral and rotational restraints at one end and no restraints at the other end (compound walls, parapet walls, etc.). 1.5 h

 Table 2 [Effective length of walls of length L] Last position effective length Continuous and supported by cross walls 0.8 liters Continuous at one end and supported by cross walls at the other end 0.9 l Wall supported by cross walls at each end 1.0 l free at one end and continuous at the other end 1.5 liters Free at one end and supported by cross wall at other end 2.0 li

## 2. partition walls

Partition walls are constructed to divide the floor area for different utilities in framed structures. They rest on the floor. They do not take the load off the floor and ceiling. They only have to carry self-weights. That’s why partition walls are usually thin. Table 8.4 shows the differences between load bearing walls and partition walls. Depending on the requirement these walls can be brick partition, clay block partition, glass partition, wood partition, and aluminum and glass partition.

## difference between load bearing and partition walls

The difference between a load bearing wall and a partition wall is given in the following table:
