Walls and Its Type - Civil ENGINEERING study

Walls are built to partition living area into different parts.They impart privacy and protection against temperature, rain and theft. 

Walls may be classified as 

  • 1. Load bearing walls 
  • 2. Partition walls. 

1. Load Bearing Walls: 

  • If beams and columns are not used, load from roof and floors are transferred to foundation by walls. Such walls are called load bearing walls. 
  • They are to be designed to transfer the load safely. 
  • The critical portion of the walls are near the openings of doors and windows and the positions where concrete beams rest. 

    Minimum wall thickness used is 200 mm. It is also recommended that the slenderness ratio of wall defined as ratio of effective length or effective height to thickness should not be more than 27. The effective height and effective length of a wall may be taken as shown in tables respectively.

 

 

Effective height of walls in terms of actual height H

Sno End Condition Effective Height
 1 Lateral as well as rotational restraint  .75H
 2 Lateral as well as rotational restraint at one end and only  lateral restraint at other  .85H
 3  Lateral restraint but no rotational restraint at both ends  1.0H
 4  Lateral and rotational restraint at one end and no restraint at other
ends (compound walls, parapet walls etc.).		  1.5H
 

Effective length of walls of length L

Sno End Condition Effective LENGHT
 1 continuous and supported by cross walls  .8L
 2 Continuous at one end and supported by cross walls at the other end  .9L
 3 Wall supported by cross walls at each end  1.0L
 4 Free at one end and continuous at other end  1.5L
5 Free at one end and supported by cross wall at other end 2.0L

 

2. Partition Walls: 

  • In framed structures partition walls are built to divide floor area for different utilities. 
  • They rest on floors. They do not carry loads from floor and roof. 
  • They have to carry only self-weight. Hence normally partition walls are thin. 
  • Table shows the differences between load bearing walls and partition walls.
  •  Depending upon the requirement these walls may be brick partition, clay block partition, glass partition, wood partition, and aluminum and glass partition.

 

 

Differences between load bearing and partition walls

S No Load Bearing Wall Partition Wall
1 They carry loads from roof, floor, self-weight etc. They carry self-weight only.
2 They are thick and hence occupy more floor area. These walls are thin and hence occupy less floor area.
3 As the material required is more,the construction cost is more. As the material required is less, the construction cost is less.
4 Stones or bricks are used for the construction. Stones are not used for the construction of partition walls
