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

AIM: To sketch a plan of G+1 floor residential building according to vaastu shastra and listing down the names of the structural drawings required to be provided to the construction.

INTRODUCTION TO VAASTU SHASTRA:-

Vaastu shastra :-

• Vaastu shastra is the ancient Indian science of architecture and acts as a guideline to design your home in the way that enhances positive energy.
• Our nature is adundant with powerhouse of energy sources 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 utilise properly to enhance the positive energy at home.
• A good home needs to radiate the right kind of energy.
• A person swelling in a house comes undr the influence of a 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 .
• Four inter cardinal direction 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:-

Rooms should be preferably be square or rectangle.

• Room Basics:-

Rooms should be airy , well lit , bright and clean.

• Home center:-

Centre of the house should be an empty space.

• Stairs and furniture :-

Heavy furnitures 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 facing the bed is strictly avoided. Mirrors in the bedroom need to be placed in such a way that the bed cannot be seen.

Auspicious directions as per vaastu shastra :

• Kitchen :-

South-east is the best direction to 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 best.

• Under ground tanks :-

North-east is the best.

South-west to be avoided.

PROCEDURE :-

Sketch of G+1 residential building floor plan ( plan is same for grond floor and first floor ).

Dimensions of plan :-

Bed room 1 = 4.0 x 3.0

Bed room 2 = 3.6 x 3.0

Dinning = 2.3 x 4.3

Living hall = 4.0 x 5.4

Kitchen = 2.6 x 3.0

Pooja = 1.5x 1.3

Portico = 4.0 x 4.2

Bath = 1.4 x 1.5

w.c = 1.3 x 1.7

Store = 1.3 x 1.4 ( All dimensions are in meters (m ) ).

Other Dimensions :

• Thickness of external / internal wall = 23m
• Thickness of slab = 25m
• Dimension of column = 3 x 0.3 m
• Dimension of beam = 3 x 0.45 m
• Height of the wall of ground floor = 4m
• Height of the wall of first floor = 5 m .

Calculation of loads :-

1. Dead load calculation :-

A. Dead load of columns :-

• Dimensions of columns = 0.3m x 0.3m
• Height of column = ( slab thickness x 2 ) + Height of wall of ground floor + height of wall for first floor )

= (0.25 x 2 ) + 4 +3.5 = 8m.

• Total volume of one column = 0.3 x 0.3 x 8

= 0.72m3.

• Unit weight of RCC = 25 KN/m3 (As confirming from IS 875: Part – 1 ).
• Dead load of one column = Volume of column x unit weight of RCC

= 0.72 x 25 = 18 KN.

B . Dead load of Beams:

• Dimension of Beam = 0.3 x 0.45 m
• Total volume of beam per meter length = 0.3 x 0.45 x 1m

= 0.135 m3

• Unit weight of RCC = 25 KN/m3 (As confirm from IS 875: Part -1 ).
• Dead load of beam per unit meter meter length = 25 x 0.135

= 3.375 KN.

C. Dead load of slabs :

• Slab is always designed for the span of 1m2. Hnece, assume size as 1x1 m
• Thickness of slab = 0.25 m
• Unit weight of RCC = 25 KN/m3 ( As confirming to IS 875 : part -1 ).
• Total volume of slab per meter length = 1x1x0.25

= 0.25 m3.

• Dead load of slab per square meter span = 0.25 x 25 x 1

= 6.25 KN.

D. Dead load of Walls :

• Thickness of external / internal wall = 0.23m.
• Part - Unit weight of brick masonry = 20 Kn /m3 ( As confirming from IS 875 : part 1 ).
• Height of ground floor wall = 4m.
• Dead load of ground floor wall per unit weight length = ( volume of wall per 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 wall per unit meter length = 3.5 x 0.23 x 1 x 20

= 16.1 KN.

• Total weight of both floor = 18.4 + 16.1 = 5 KN.

2. Live load calculation :-

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

• Living / dining - 2 KN/m2
• Kitchen - 2 KN/m2
• Bed room - 2KN/m2
• Wash room - 2KN/m2
• Toilet - 2KN/m2
• Store room -3 KN/m2
• Stair case - 3KN/m2

3. Wind load calculation :

• If the height of the building is more than 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 nit to be considerd.

The names of the structural drawings required to be provided to the site foe construction are as follow:

• Centre line drawing.
• Footing and column layout with reinforcement details.
• Column schedule with reinforcement details.
• Plinth beam layout with reinforcement details.
• Each floor beam layout with reinforcement details.
• Lift pit and headroom with reinforcement details.
• Each floor plans.
• Foundation plan.
• Block plan.
• Roof slab layout.
• Column layout.
• Column sections.
• Septic tank details.
• Overhead water tank details.
• Furniture plan.
• Road drainage plan.
• Setting out plan.
• Section drawings of buildings.
• Plumbing details.
• Electrification deatials.

RESULTS:

• The plan of G+1 floor residenstial building prepared with consideration of concept of VAASTU SHASTRA.
• The load calculations are done as per IS code considerations.

References and IS codes used for design :-

• IS 875:1987 (part 1) for dead load calculation.
• IS 875:1987 (part 2) for live load taken.
• IS 875:1987 (part 3) for wind load assumption.
• IS 456: 2000 for reinforced concrete.
