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

AIM:- To sketch a G+1 floor residential plan, according to Vaastu Shastra, and list down the names of the structural drawings required to be provided to the site for construction.

Also, to assume the sizes of the structural elements (Column, Beam, Slab, etc.,) and accordingly calculate the individual corresponding loads from the members as per IS code.

INTRODUCTION:-

In this project I will draw a plan according to Vaastu Shastra for a G+1 residential building. Also I will explain each and every details regarding vaastu shastra according to the position of room. In this project, I have calculated dead load of this G+1 residential building components likecolumn, beam, slab,walls etc., along with live load.

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.

Assume total 17 number of columns of height 6.5 meter for G+1 residential building

Unit weight of reinforced cement concrete= 25 KN/m3.

Dead load of a single column= (Volume of column X unit weight of reinforced cement concrete)

= (0.3X0.3X6.5X17) = 9.945 KN

Dead load for 25 number of column= (Volume of column X unit weight of reinforced cement concrete) X number of column

= ( 0.3 X 0.3 X 6.5 X 25)X17 = 248.625 KN

Dead load of beam:-

1).Calculation of dead load for plinth beam:-

Assume the size of plinth beam= 250mm X 350mm = 0.25 meter X 0.35 meter

• Wash Room - 2 kN/m²
• Toilet - 2 kN/m²
• Store Room - 2 kN/m²
• Puja Room - 2 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.
