TYPE-1 | PLAIN SHADE STEEL FRAME STRUCTURES | PLAIN TYPE STEEL FRAME STRUCTURE WEIGHT CALCULATION

(i). Weight of Steel structure for pipes and square plates and 

(ii). No. of pipes required to make this frame

 

GIVEN DATA:

Thickness of pipe = 2mm

Section of pipe = 2" x 2"

Square plate = 12" x 12" x 2mm

 

Solution:

(A). Frame Calculation:

1. Length of pipe in horizontal direction = 24'

No. of pipes of length = 4

 

2. Length of pipe in vertical direction = 20'

No. of pipes of length = 5

 

3. Height of Column = 12'

No. of pipes = 4

 

4. Total length = 24' x 4 + 20' x 5 + 12' x 4 = 244 Ft

Section of pipe = 2"x 2"

Since 1" = 25.4mm

8 x 25.4 = 203.2mm

 

L = (2"+2") x 2 = 8" = 203.2mm

L = (L+B) x 2 = (2"+2") x 2 = 8"

Thickness of pipe = 2mm

Section of Flat plate = 203.2mm x 2mm

 

Weight of Steel bar in kgs/ft = Area of bar / 416.56 = (203.2 x 2) / 416.56 = 0.975 kgs/ft

 

5. Total length of Hollow square pipe = 244'

Weight of Hollow square pipe required = 0.975 x 244' = 237.9 kgs

 

6. No. of pipes required = Total length required / length of each pipe Standard length of Square pipe = 20' = 244 / 20 = 12.2 pipes

 

(B). Square Plate

Size of Square plate = 12" x 12" x 2mm  

No. of Square plate = 4

 

Weight of Square plate in kgs =Volume of plate x Density of steel x No. of plates

1" = 25.4mm       

12" = 25.4 x 12 = 304.8mm

304.8mm = 0.304m

 

Dimension in metres = 0.304 x 0.304 x 0.002 x 7850 x 4 = 5.803 kgs

 

(C). Total weight of Steel required = Weight of frame + Weight of Square plate

= 237.9 + 5.803

= 243.703 kgs

 

 

TYPE-2 | INCLINED SHADE STEEL FRAME STRUCTURES | INCLINED TYPE STEEL FRAME STRUCTURE WEIGHT CALCULATION

(i). Weight of Steel structure for pipes and square plates and

(ii). No. of pipes required to make this frame.

 

GIVEN DATA:

Detail Section of pipe 1.5"x1.5"       

Thickness of pipe = 2mm

Square plate = 9" x 9" x 2mm

Solution:

(A) Frame calculation:

1. Length of pipe in horizontal direction = 15'

No. of pipes of length = 2

 

2. Length of pipe in vertical direction = 24'

No. of pipes of length = 9

 

3. Height of Column = 16'    

No. of pipes = 4      

c = √ (a² + b²)

c = √ (7.5² + 4²)

c = 8.5

 

4. Length of inclined pipe = 8.5 x 2 = 17'     

No. of pipes = 7

 

5. Total length = 15' x 2 + 24' x 9 + 16' x 4 + 17 x 7 = 429.0 Ft

Section of pipe = 1.5" x 1.5"

Since 1" = 25.4mm 6 x 25.4 = 152.4mm

L = (L+B) x 2

L = (1.5" + 1.5") x 2 = 6" = 152.4mm

Thickness of pipe = 2mm

Section of Flat plate = 152.4mm x 2mm

Thickness of pipe = 2mm

 

Weight of Steel bar in kgs/ft = Area of bar / 416.56

= (152.4 x 2) / 416.56

= 0.731 kgs/ft

 

6. Total length of Hollow square pipe = 429'

 

7. Weight of Hollow square pipe required = 0.731 x 429 = 313.599 kgs

 

8. No. of pipes required = Total length required / length of each pipe Standard length of Square pipe = 20'

= 429 / 20

= 21.45 pipes

 

(B). Square Plate

Size of Square plate = 9" x 9" x 2mm      

No. of Square plate = 4

 

Weight of Square plate in kgs = Volume of plate x Density of steel x No. of plates

1" = 25.4mm

9" = 25.4 x 9 = 228.6mm

228.6mm = 0.2286m

Dimension in metres = 0.2286 x 0.2286 x 0.002 x 7850 x 4 = 3.281 kgs

 

(C). Total weight of Steel required = Weight of frame + Weight of Square plate

= 313.599 + 3.281

= 316.88 kgs

 

 

TYPE-3 | ARCH TYPE SHADE STRUCTURAL STEEL FRAME STRUCTURES | ARCH TYPE STEEL FRAME STRUCTURE WEIGHT CALCULATION

From the given figure find

(i). Weight of Steel structure for pipes and square plates and

(ii). No. of pipes required to make this frame.

 

GIVEN DATA:

Dia of pipe = 2"      

Thickness of pipe = 2mm

Dia of round plate = 15"

The thickness of plate = 2mm

Solution:

(A). Frame Calculation

1. Length of pipe in horizontal direction = 14'

No. of pipes of length = 2

 

2. Length of pipe in vertical direction = 20'

No. of pipes of length = 9

 

3. Height of Column = 18'

No. of pipes = 4

Segmental Arc Length = L = (8B - 2R)/3

Where,

R = radius of circle

B = Ѵ (R² +H²)

B = Ѵ (72 + 2.52) = 7.433'

L = (8 x 7.433 - 2 x 7) / 3 = 15.154' Ft

 

4. Length of Arch pipe = 15.154'

No. of pipes = 5

 

5. Total length = 14' x 2 + 20' x 9 + 18' x 4 + 15.154 x 5 = 355.77 Ft

 

Dia of pipe = 2" = 50.8mm

Radius = d/2 = 25.4mm

L = 2 x π x r = 2 x π x 25.4 = 159.59mm

Thickness of pipe = 2mm

Section of Flat plate = 159.59mm x 2mm

 

Weight of Steel bar in kgs/ft = Area of bar / 416.56

= (159.59 x 2) / 416.56

= 0.766 kgs/ft

 

6. Total length of Round Hollow pipe = 355.77'

 

7. Weight of Round Hollow pipe required = 0.766 x 355.77 = 272.519 kgs

 

8. No. of pipes required = Total length required / length of each pipe Standard length of Round pipe = 20'

= 355.77 / 20

= 17.78 pipes

 

(B). Round plate

Dia of Round plate = 15"

Thickness = 2mm    

No. of Round plate = 4

 

Weight of Round plate =Volume of plate x Density of steel x No. of plates

 

Dimension in metres = Area of plate x thickness of plate x Density of steel x nos

1" = 25.4mm

15" = 25.4 x 15 = 381mm

381mm = 0.381m

 

= (π/4) x d2 x thickness of plate x density of steel x no.s

= (π/4) x 0.3812 x 0.002 x 7850 x 4 = 7.159 kgs

 

(C). Total weight of steel required = Weight of frame + Weight of Round plate

= 272.519 + 7.159

= 279.678 kgs
