A masonry wall is a wall made up of structural units like red brick, blocks, etc. If you have to analyze any structure then you have to apply different loads on the frame structure.
To know the self-load of the different structures like parapet walls, partition walls, or exterior walls we need to calculate the volume of the member, and then we have to multiply by its density.
Here, we will see the step-by-step process to calculate the self-load of the wall.
Numerical to calculate self weight of brick wall
Question:- Calculate the self-weight of the wall having a length of 4 meters, a height of 3 meters, and a width of 230 mm.
Solution:-
Considering the wall dimension below,
Length of wall = 4 meter
Height of wall = 3 meter
Width of wall = 0.23 meter
We have,
Self Weight = Unit weight x Volume
Given,
Unit weight = 1920 Kg/m.cube
Step1 :- Calculate Volume of the wall
Volume = L x H x W
= 4 x 3 x 0.23
= 2.76 meter cube
Step3 :-Self Weight of wall
Weight = Unit weight x Volume
= 1920 x 2.76
= 5299.20 Kg.
With Plaster,
Weight = Unit weight x Volume
= 2100 x 2.76
= 5796 Kg.
Step3 :- Self Weight of wall per meter
Weight/meter = Total Self Weight/Length
= 5299.20/4
= 1324.8 Kg/meter.
With Plaster,
Weight/meter = Total Self Weight/Length
= 5796/4
= 1449 Kg/meter.
