How to calculate the dead load of the brick wall?/ Calculating the self-weight of the brick wall.

Let us consider a brick wall as shown in the below-given drawing.

Given data:

Length of the wall = 4m.

Height of the wall = 3m.

The thickness of the wall = 0.23m.

The self-weight of the wall is calculated by the formula

= [unit weight × volume of the wall]

The volume of the brick wall

= [length × height × thickness]

= [ 4m. × 3m. × 0.23m.]

= 2.76 cum.

As per IS: 875(Part-1)-1987, the unit weight of masonry brick ( burnt clay) is 1920kg /cum.

The self-weight of the wall

= [unit weight × volume of the wall]

= [ 1920 kg/cum. × 2.76 cum.]

= 5299.20 kg.

Now, the question is " What will be the dead load of the plastered wall?"

As per IS: 875, the unit weight of cement plaster or cement mortar is 2080 kg/cum.

So, to calculate the dead load of the plastered brick wall, the practical way is to consider an overall unit wt. of 2100 kg/cum.

Now, the self-weight of the finished wall

= [unit weight × volume of the finished wall]

= [ 2100 kg/cum. × 2.76 cum.]

= 5796 kg.

Note: Here, the wall thickness is considered (inclusive of plaster) the same as above.

Thank you for going through these calculation steps. Have a good day ðŸ˜„.
