How much steel is required for 1500 sq ft house

How much steel is required for 1500 sq ft house, hi guys in this article we know about quantity of steel is required for 1500 square feet house. Actual Steel calculation is based on as per design but if design is not given then Steel calculation is based on Thumb Rule on experience basis.

💐— WATCH THIS VIDEO–💐

How much is steel is required for 1500 sq ft house is based on different type of criteria

1) type of structure (Load Bearing/Framed)

2) Purpose of structure (Load depends on the utility)

3) Type of dia of Bar

4) Size height of column and length of beam (in terms of height, as requirement varies according to construction i.e. whether horizontal or vertical. )

5) Most important is foundation type(depends on soil bearing conditions)

For general residential building of ground floor house we have to calculate Steel quantity. We use different types of Thumb Rule for steel calculation all type of RCC structure footing, column, beam & RCC slab.

How much steel is required for 1500 sq ft house

Now taking various Thumb Rule for Steel quantity calculation for 1500 square feet house

1) thumb rule for steel in rcc slab is 80 kg/cubic meter of wet volume of concrete

2) thumb rule for steel in beam is 120 kg/cubic meter of wet volume of concrete

3) thumb rule for steel in column is 160 kg/cubic meter of wet volume of concrete

4) thumb rule for steel in footing is 40 kg/cubic meter of wet volume of concrete

5) thumb rule for steel in rcc structure is 120 kg/cubic meter of all calculated wet volume of concrete.

6) thumb rule for steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area.

If we take last thumb rule point (6), thumb rule for steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area.

If built area is 1000 sq ft house we require steel quantity

= 3.5 × 1000 = 3500 Kg

= 4 × 1000 = 4000 kg

3500 Kg to 4000 Kg of Steel quantity is required for construction of 1000 square feet house.

If built area is 1200 sq ft house, we require steel quantity

= 3.5 × 1200 = 4200 Kg

= 4 × 1200 = 4800 kg

4200 Kg to 4800 Kg of Steel quantity is required for construction of 1200 square feet house.

How much steel is required for 1500 square feet house ground floor?

For the construction of residential building of ground floor we have RCC structure like footing, column, beam and slab. Taking one rough design of 1500 square feet house having different dimension of rcc structure like footing, column, beam and slab are following:

1) footing size = 1500 mm × 1500mm × 300 mm

Length of footing = 1500 mm

Width of footing = 1500 mm

Height of footing = 300 mm

Depth of earth exacavation = 1500 mm

Concrete size in footing = 1200mm×1200mm×300mm

No of footing = 15

Wet volume of concrete in all 15 no of footing = 1.2 m × 1.2 m × 0.3 m × 15 = 6.48 m3

thumb rule for steel in footing is 40 kg/cubic meter of wet volume of concrete

Steel quantity = 6.48 × 40 = 259 Kg

259 Kg of Steel required in footing RCC structure of 1500 square feet of house

2) column size = 300 mm × 400 mm

No of column = 15

Height above dpc = 3000 mm

Height above rcc slab = 900 mm

Depth of earth exacavation = 1500 mm

Total height of column = 5400 mm

Wet volume of concrete for all 15 column

= 0.3 × 0.4× 5.4 × 15 = 9.72 m3

thumb rule for steel in column is 160 kg/cubic meter of wet volume of concrete

Steel quantity = 9.72 × 160 = 1555 kg

1555 Kg of Steel required in column RCC structure of 1500 square feet of house.

3) plinth beam size = 300mm × 300 mm

Width of beam = 300 mm

Depth of beam = 300 mm

Overall length of all beam = 300 ft = 90000 mm

Wet volume of concrete = 0.3 × 0.3 × 90 = 8.1 m3

thumb rule for steel in beam is 120 kg/cubic meter of wet volume of concrete

Steel quantity = 8.1 × 120 = 972 kg

972 Kg of Steel required in plinth beam RCC structure of 1500 square feet of house.

4) door beam size for external wall = 225mm × 150 mm

Overall length for external beam = 160 ft = 48000 mm

Steel = 0.225 × 0.15 × 48 × 120 = 195 Kg

Door beam size for internal wall = 125 mm × 150 mm

Overall length for internal beam = 140 ft = 42000 mm

Steel = 0.125 × 0.15 × 42 × 120 = 95 Kg

Steel for door beam = 195 + 95 = 290 kg

290 Kg of Steel required in door beam of 1500 square feet of house

5) roof wall beam size for external wall = 225 mm × 200 mm

Overall length for external beam = 160 ft = 48000 mm

Steel = 0.225 × 0.2 × 48 × 120 = 259 Kg

Roof wall beam size for internal wall = 125 mm × 200 mm

Overall length for internal wall beam = 140 ft = 42000 mm

Steel = 0.125 × 0.2 × 42 × 120 = 126 Kg

Steel for roof beam = 259 + 126 = 385 kg

385 Kg of Steel required in roof wall beam of 1500 square feet of house

6) rcc roof slab = 50′ × 30’×6″

Length of slab = 50 feet

Width of slab = 30 feet

Thickness of slab = 6 inch = 0.5 feet

Volume = 50′ × 30’× 0.5′ = 750 cubic feet

1 m3 = 35.3147 cu ft

Volume = 750/35.3147 = 21.238 m3

thumb rule for steel in rcc slab is 80 kg/cubic meter of wet volume of concrete

Steel = 21.238 × 80 = 1699 Kg

1699 Kg of Steel required in rcc roof slab of 1500 square feet of house

Now Total weight of Steel required for 1500 square feet house

Footing = 259 kg

Column = 1555 kg

Plinth beam = 972 kg

Door beam = 290 kg

Roof beam = 385 kg

Roof slab = 1699 kg

Total weight of steel = 5160 Kg

Suppose 90 kg steel used in chhajjas & other rcc structure

Than total weight of steel = 5160 + 90 = 5250 kg

5250 Kg of steel ( 259 kg in footing, 1555 kg in column, 972 kg in plinth beam, 290 kg in door beam, 385 kg in roof beam, 90 kg in chhajjas & 1699 Kg in rcc roof slab) is required for construction of residential building of ground floor of 1500 square feet house. This is a general guidelines and actual quantity may vary for special design, thanks.
