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 site.

INTRODUCTION TO VAASTU SHASTRA :

Vaastu Shastra :

• Vastu 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 abundant with powerhouses 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 dwelling in a house comes under 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 intercardinal 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 Shatra.
• North - Wealth
• South - Dharma
• West and East - Overall prosperity

Basic principles of Vastu 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 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 facing the bed is strictly not allowed. Mirrors in the bedroom need to be placed in such a way that the bed cannot be seen.

Auspicious directions as per Vastu Shastra :

• Kitchen - South-east is the best direction fo 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.
• Over Head Tanks - West is the best.
• Under ground Tanks - North-east is the best,South-west to be avoided.

PROCEDURE :

Sketch of the ground floor plan :

Dimensions of Ground Floor plan :

• Drawing/Living Room - 4.76m * 3.8m
• Dining Room - 4.5m * 3.5m
• Bed Room - 4.5m * 4m
• Store Room - 3.5m * 2.8m
• Wash Room - 2.5m * 3.5m
• Guest Room - 4.2m * 3.3m
• Kitchen - 3.2m * 3.8m
• Parking Area - 6.23m * 3.5m
• Pooja Room - 2.8m * 3.5m

Sketch of first floor plan :

Dimensions of First Floor Plan :

• Bed Room : 1 - 4.5m * 4m
• Toilet : 3.5m * 2.5m
• Study Room : 3m * 3.3m
• Bed Room 2 : 4m * 3.5m
• Terrance : 13.69m * 4m

Other Dimensions :

• Thickness of External/Internal Wall - 0.23m (230mm)
• Thickness of slab - 0.25m (250mm)
• Dimensions of column - 0.3m * 0.3m
• Dimensions of beam - 0.3m * .45m
• Height of the wall of Ground floor - 4m
• Height of the wall of First floor - 3.5m

CALCULATION OF LOADS :

1) Dead load Calculations :

A) Dead load of Columns :

• Dimension of column=0.3m*0.3m(300mm*300mm)
• Height of column=(Slab thicknessX2)+Height of wall for ground floor+Height of wall for first floor =(0.25*2)+4+3.5=8m
• Total volume of one Column=0.3*0.3*8m=0.72m^3
• Unit weight of RCC=25 kN/m^3(as Conforming from IS 875: Part-I)
• 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 * 0.45m (300mm X 450mm)
• Total volume of Beam per meter length = 0.3 * 0.45 *1 = 0.135m^3
• Unit weight of RCC = 25KN/m^3 (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 designed for the span of 1 m^2. Hence, assume size of slab as 1m * 1m
• Thickness of slab = 0.25m(250 mm)
• Unit weight of RCC = 25kN/m^3 (as Conforming from IS 875: Part-I)
• Total volume of Slab per Sq.meter span area =1m *1m* 0.25m = 0.25m^3
• Dead Load of slab per Sq.m span area = 0.25 X 25 = 6.25kN

D) Dead load of Walls :

• Thickness of External/Internal wall = 0.23m (230mm)
• Unit Weight of Brick Masonry = 20 kN/m^3 (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 meter length*Unit weight of Brick Masonry= 4*0.23*1*20 =18.4 kN
• Height of First floor wall = 3.5 m
• Dead Load of First floor wall per unit meter Length = Volume of wall per meter length * Unit weight of Brick Masonry 3.5*0.23*1*20 =16.1kN
• Total Weight of both Ground and First Floor Walls per unit meter Length = 18.4 + 16.1= 34.5kN

2) Live load Calculations :

As per IS -875 Part-2, for residential building, Live Loads are taken as :

• Living/Dining - 2 kN/m^2
• Kitchen - 2 kN/m^2
• Bed Room - 2 kN/m^2
• Wash Room - 2 kN/m^2
• Toilet - 2 kN/m^2
• Store Room - 2 kN/m^2
• Terrace - 3 kN/m^2
• Staircase - 3 kN/m^2

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
• Each floor beam layout with reinforcement details
• Lift pit and head room with reinforcement details
• Each Floor plans
• Foundation plan
• Block plan
• Roof slab layout
• Column layout
• Column sections
• Septic tank detail
• Overhead water tank detail
• Furniture plan
• Road drainage plan
• Setting out plan
• Section drawings of buildings
• Plumbing details
• Electrification details

Results :

• The plan of G+1 Floor Residential Building is prepared with consideration of Concept of Vaastu Shastra.
• The load calculations 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 Reinforced Concrete
