'Y'‐Type Column With Arch Quantity Survey | Volume Of Concrete | Area Of Shuttering | Area Of Paint

 

1. 'Y'‐type Column with arch Volume Of Concrete Calculation

2. 'Y'‐type Column with arch Area Of Shuttering Calculation

3. 'Y'‐type Column with arch Area Of Paint Calculation

 

Solution:

1. Volume of Concrete = front area of Column x thickness of Column

To find out front area of Column, divide front area of column in to three parts

1. Area Of Square = L X B = 0.80 X 0.80

= 0.64 m²

 

2. Area Of Circle = π/4 X D²

= π/4 X 0.8²

= 0.502m²

 

Deduction of circle area from square area = 0.64 ‐ 0.502

Area for four panels = 0.138 m²

Area of each panel   = 0.138/4

= 0.0345 m²

 

Front area of column:

1. Part‐1 = 0.0345 m²

2. Part‐2 = 0.0345 m²

3. Part‐3 = L x B = 0.40 x 2.50 = 1.0 m²

 

Total Area = 0.0345 + 0.0345 + 1.0 = 1.069 m2

 

Therefore,

Volume of Concrete = Front Area x thickness of Column

= 1.069 x 0.40

= 0.4276 m³

 

2. Shuttering Area = front area of column + back area of column + side area of column + side area of the column

Therefore side area can find out by dividing the side area into two parts :

 

Part‐1:

Side area for part‐1 = L x B

= 0.40 x 2.10

= 0.84 m²

 

Part‐2:

Side area for part‐2 = L x B

Formula to find out arc length for quarter circle: arc length

= 2 x π x r x 1/4

= 2 x π x 0.40 x 0.25

= 0.628 m

= L x B

= 0.40 x 0.628

= 0.251 m²

Hence total side area = A1 + A2

= 0.84 + 0.251

= 1.091 m²

 

Shuttering Area = front area of column + back area of column + side area of column + side area of column

= 1.069 + 1.069 + 1.091 + 1.091

= 4.32 m²

 

3. Area of paint = Area of Shuttering

= 4.322 m²
