How to calculate dead load of brick wall or block wall?

Dead Load

Dead load is the own weight of structure which include the weight of the structure, and areas such as walls, concrete floors, or floors.

Dead loads are also called fixed or permanent loads. Building materials are not dead loads until they are built in a permanent condition. 

How do you find the dead load of a building?

Dead load = volume of member x unit weight of materials

By calculating the size of each structure or element and multiplying it by the unit weight of it, can determine an accurate dead load for each component

Each country defines the density of the different materials in specific codes. In india, it is defined in part 1 of IS875.

How to calculate dead load of brick wall or block wall?

TEAM LCETED 

Lets We will Consider a wall measurements as,

Length of brickwall or blockwork = 2.5 meter

Height of brick wall or blockwork = 3 meter

Thickness of brickwall or blockwork = 9″= 228.6mm = 0.2286 meter

The density of the brick wall with mortar varies between 1900-2100 kg/m³

The density of the block wall with mortar varies between

Solid concrete blocks :- 1500 to 2000kg/m³

Hollow concrete blocks:- 1000 to 1500kg/m³

In block work density may vary from each type of block we use in masonry work

We use brick work density for this calculation So we consider self weight of brick wall is 2200 kg/m3 in this calculation

Volume Of Brick Wall

Volume of brickwall = l × b ×h

Length = 2.5 meter

Width = 0.2286

Height of wall = 3 meter

Volume = 2.5m× 0.2286m× 3m

Volume of brick wall = 1.7145 m³

Dead Load Of Brick Wall

Weight = volume × density

As We mentioned early density of the brick wall with mortar varies between 1900-2100 kg/m³

So,

Dead load = 1.7145 m³ × 1900 kg/m³

Dead load = 3257.55 kg/m

How to convert kg/m³ to kn/m³

It can be converted by dividing kilogram per meter cube by 101.971 we will get 31.945kN/m
