Sketch a G+1 residential plan according to Vaastu Shastra and Calculation of Loads as per IS code

Aim: Sketch a G+1 floor residential plan, according to vaastu shastra, and listing down the name of the structural drwaings required to be provided to the consruction site.

Introduction to vaastu shastra:

Vaastu shastra:

• Vaastu shastra is the anciient indian science of architechture and acts as guideline to design your home in the way that enhances positive energy.
• Our nature is abundant with powerhoses of energy sourses like the sun, wind, moon, water, earth and fire.
• Effect of sunrays, flow of winds, pull of earth's magnetic field and other such cosmic energies utilies properly to enhance the positive energy at home.
• A good home needs to radiate the right time of energy.
• A person dwelling in a house comes under the influence of the specific energy field.
• Architectural changes are not possible for a ready to move in house.

Significance of eight directions:

• Four cardinal direction are North, South, East and West.
• Fore intercardinal directions are North-East, North-West, South-East and South-West.
• Each direction signifies an aspect of life and is governed by various gods as per vaastu shastra.
• North - Wealth
• South - Dharma
• West and East - Overall prosperity.

Basic principles of vaastu shastra:

• Shape: Room should be preferably be square or rectangle.
• Room basics: Room should be airy, well lit, bright and clean.
• Home center: Centre of the house should be an empty space.
• Stairs and furniture: Heavy furniture should be kept in the south-west direction.
• Water: Avoid keeping plants and water features in the bedroom.
• Dining table: Dining space should be near the kitchen and not near the main door.
• Mirror placement: Mirror placing the bed is strictly not allowed. mirrors in the bedroom need to be placed in such a way that the bed can not be seen.

Auspicious directions as per vaastu shastra:

• Kitchen: South-East is the best direction of kitchen, North-East to be avoided.
• Staircase: South-west is the best for stairs, North-East to be avoided.
• Toilet: North-West is the best, North-East to be avoided.
• Master bedroom: South-West is the best.
• Guest room: North-West is the best.
• Living room: North-West is the best.
• Overhead tanks: West is the best.
• Underground tanks: North-East is the best, South-West to be avoided.

Procedure:

Sketch of ground floor plan:

Dimensions of ground floor plan:

Drawing/Living room : 22'2" x 11'

Dining room : 7' x 11'

Kitchen : 8'4" x 7'

Pooja room : 6' x 6'4"

Guest room : 10'10" x 9'8"

Parking : 15' x 9'4"

Master bedroom : 11' x 12'10"

Sketch of first floor plan:

Dimensions of first floor plan:

Living room : 10'10" x 20'

Guest room : 11'2" x 11'

Kitchen : 7' x 11'

Dinning : 11'4" x 11'

Master bedroom : 11' x 12'10"

Terrace : 8'4" x 7'

Other dimensions:

Thickness of external/Internal wall : 9"

Thickness of slab : 6"

Dimensions of column : 0.3 m x 0.3 m

Dimensions of beam : 0.3 m x 0.45 m

Height of the wall of ground floor : 4m

Height of the wall of first floor : 3.5m

Calculations of load:

1) Dead load calculations :

a) Dead load of columns :

Dimension of column = 0.3m x 0.3m (300mm x 300mm)

height of column = (Slab thickness x2) + height of wall for ground floor + height of wall for first floor

= (0.25 x2) +4+3.5

= 8 m

Total volume of one column = 0.3*0.3*8

= 0.72 m3

Unit weight of RCC = 25 KN/m3 (As conforming from IS 875:part-1)

Dead load of one column = Volume of column*unit weight of RCC

= 0.72*25

= 18 KN

b) Dead load of beams:

Dimension of beam = 0.3m x 0.45m (300mm x 450mm)

Total volume of beam per meter length = 0.3 x 0.45 x 1

= 0.135 m3

Unit weight of RCC = 25 KN/m3 (As conforming from IS 875: Part-1)

Dead load of beam per unit meter length = 25 x 0.135

= 3.375 KN

c) Dead load of slabs :

Slab is always design for the span of 1 m2. Hence, assume size of slab as 1m * 1m * 0.25m = 0.25 m3

Dead load of slab per sq. m. span area = 0.25 x 25

= 6.25 KN

d) Dead load of walls :

Thickness of external/internal wall = 0.23m or 230 mm or 9"

Unit weight of brick masonry = 20 KN/m3 (As conforming from IS 875:Part-1)

Height of ground floor wall = 4 m

Dead load of ground floor wall per unit meter length = volume of wall per unit meter length X Unit weight of brick masonry = 4 x 0.23 x 1 x 20 = 18.4 KN

Height of first floor wall = 3.5m

Dead load of first floor wall per unit meter length = Vol. of wall per meter length X Unit weight of brick masonry = 3.5 X 0.23 X 1 X 20

= 16.1 KN

Total weight of both ground and first floor walls per unit meter length = 18.4 + 16.1 = 34.5 KN

2) Live load calculations:

As per IS - 875 part-2, for residential building, live loads are taken as :

• Living / Dining - 2 KN/m2
• Kitchen - 2 KN/m2
• Bed room - 2 KN/m2
• Wash room - 2 KN/m2
• Toilet - 2 KN/m2
• Terrace - 3 Kn/m2
• Staircase - 3 Kn/m2

3) Wind load calculations :

• If the height of the building is more then 10 meters then building need to be designed for wind load.
• But, in this case, height of the building is 8 meters. thus, wind load need not to be considered.

The names of the structural drawings required to be provided to the site for construction are :

• Centre line drawing
• Footing and column layout with reinforcement details.
• Column schedule with reinforcement details
• Plinth beam layout with reinforcement details
• First floor beam layout with reinforcement
• First floor slab layout with reinforcement
• Lift pit and headroom reinforcement

Results:

• The plan of G+1 floor residential building is prepared with consideration of concept of vaastu shastra.
• The load calcualations are done as per the IS code considerations.

References and IS codes used for the design :

• IS 875:1987 (part 1) for dead load
• IS 875:1987 (Part 2) for live load
• IS 875:1987 (part 3) for wind load
• IS 456:2000 for reinforcement concrete
