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 building plan according to Vaastu Shastra and list the names of the structural drawings required to be provided to the construction site.

  Vaastu Shastra:-

• Vastu Shastra is the Ancient Indian Science of architecture and acts as a guideline to design your home in a 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, the flow of winds, the pull of earth's magnetic field, and other such cosmic energies utilise correctly 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 a specific energy field.
• Architectural changes are not possible for a ready-to-move-in house.

   Significance of Eight directions:-

• Four cardinal directions are North, South, East and West.
• Four intercardinal directions are northeast, 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 Vastu Shastra:-

• Shape:-

        Rooms should preferably be square or rectangular.

• Room Basics:-

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

• Home centre:-

        The Centre of the house should be a space.

• Stairs and Furniture:-

        Heavy furniture should be kept in the southwest direction.

• Water:-

        Avoid keeping plants and water features in the bedroom.

• Dining Table:-

        The dining space should be near the kitchen and not the main door.

• Mirror placement:-

        A mirror facing the bed is strictly not allowed. Mirrors in the bedroom must be placed so the bed cannot be seen.

   Auspicious directions as per Vastu Shastra:-

• Kitchen:-

        South-east is the best direction for the 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.

• Main Bedroom:-

        Southwest is the best.

• Guest Room:-

        North-west is the best.

• Living Room:-

        North-west is the best.

• Over Head Tanks:-

        West is the best.

• Underground Tanks:-

        The Northeast is the best.

        South-west to be avoided.

 Dimensions of FIRST Floor plan­:-

Drawing/Living Room	-     6.09m * 5.15m
Dining Room	-     3.04m * 3.04m
Master Bed Room	-     3.04m * 3.35m

Guest Bedroom Room	-     3.04m * 3.04m
Kitchen	-     3.04m * 3.04m

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 the Ground floor	-    4m
Height of the division of First floor	-    3.5m

Calculation of loads:-

  1) Dead load Calculations:-

   A) a Dead load of Columns:- 

• Dimension of column = 0.3m * 0.3m (300mm * 300mm)

• Height of column      = (Slab thickness X 2) + Height of wall for ground floor + Height of wall for the first floor

                                        = (0.25 X 2) + 4 + 3.5 = 8 m 

• Total volume of one Column = 0.3 * 0.3 * 8

                                                 = 0.72 m^3

• Unit weight of RCC        = 25 KN/m^3   (as Conforming from IS 875: Part-1)

• Dead load of one column      = Volume of Column * Unit Weight of RCC

                                                  = 0.72 * 25 = 18 KN

       Total Column is used on both Ground, and the first floor is 18  = 18*18 KN

                                                                                        =  324 KN

  B) a 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

                                                                  = 0.135 m^3

• Unit weight of  RCC   =  25KN/m^3  (as Conforming from IS 875 : Part-1) 

• a 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 1m^2.  Hence, assume the size of the slab as 1m * 1m 

• Thickness of slab      = 0.25 m (250 mm) 

• Unit weight of  RCC   = 25 KN/m^3  (as Conforming from IS 875: Part-1)

• Total volume of Slab per Sq.meter span area   = 1m * 1m * 0.25m

                                                                           = 0.25 m^3

• Dead Load of slab per Sq.m span area = 0.25 X 25

                                                                 = 6.25 KN

   D) a 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

                                                                                  = 16.1 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 buildings, Live Loads are taken as:-

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

   3) Wind load Calculations:-

• If the building height is more than 10 meters, then the building needs to be designed for wind load.
• But, in this case, the Height of the building is 8 meters. Thus, Wind Load need not be considered.

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

1. Centre line drawing
2. Footing and column layout with reinforcement details
3. Column schedule with reinforcement details
4. Plinth beam layout with reinforcement details
5. Each floor beam layout with reinforcement details
6. Lift pit and headroom with reinforcement details
7. Each Floor plans
8. Foundation plan
9. Block plan
10. Roof slab layout
11. Column layout
12. Column sections
13. Septic tank detail
14. Overhead water tank detail
15. Furniture plan
16. Road drainage plan
17. Setting out a plan
18. Section drawings of buildings
19. Plumbing details
20. Electrification details

  Results:-

• The G+1 Floor Residential Building plan is prepared considering the 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
