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

Aim :   TO sketch a G+1 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, 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.

Objective/Importance : To know the rules and ideas about the planning of the building ,directions of the particular rooms in the building as per the Vaastu shastra.

• Project planning provides direction and standards of performance. It also helps to know about the risk and opportunities coming ahead. Plan is made and strategies are set by the considering rules and policies of the construction companies.
• Vaastu shastra is to bring perfect balance and harmony between nature, people and their place of living and working, thereby paving the way for peace, prosperity, health, happiness in the building and peoples who are living in that particular building.

Procedure :

 Vaastu shastra :

Vaastu shastra is an ancient Indian science which capitalizes on the concept of prosperity. It links person’s health and happiness directly with layouts and the construction of building.

Promotors of Vaastu shastra propagate that it is most authentic and proven advice science. They say that nature consist of 5 basic elements such as energy of planets, air, water, fire and earth. Each carries its own set of dynamics and with Vaastu one’s home and business can be synchronized.

As per promotors of shastra it creates a tremendous impact over all facts of life, i.e., health, life, education, thinking, prosperity, marriage and peace of mind. In fact “Vaastu Shastra” is the science of an ancient “Vedic Ages” of India under the guidance of which one can construct building of structures on a particular plot of land. For some people these principles are still relevant today also. As per their belief the science of  “Vaastu Shastra” controls forces of gravity and magnetic power of earth.

Presence of plants of Tulsi, Banana, Champa, Ashoka, Aawta outside the house keeps inhabitants healthy, happy and peaceful.

Requirements of Vaastu shastra:

1. The site should be square or a rectangular. If possible southwest corner should have 90 degree.
2. The main door should be on North, East or Northeast side of the plot. 2 gates are preferable, one on east and other in the north. In addition to this northeast, southwest or northwest blocks are also good.
3. Ground level should slope towards northeast and levels in southwest should be higher than other sides.
4. A bore well should be provided in north east before the construction takes place.
5. More space should be provided in the east and north compared to west and south of the complex.
6. Balcony towards north, east and northeast are preferable.
7. Kitchen is advisable in south east or northwest but never in northeast.
8. Staircase should be provided in south.

Auspicious directions as per Vaastu shastra :

• Kitchen : South-East is preferable to provide, North-East to be avoided.
• Staircase : South, South-West.
• Bathroom/Toilet : North-West is best, North-East is to be avoided.
• Master Bedroom : South-West is best.
• Guest room : North-West is best.
• Living room : North-West is best.
• Overhead tank : West is best.
• Underground tank : North-East is best, avoid it in the direction of South-West.
• Balcony : North, East and North-East is preferable.
• Extra space : East or North is best.
• Main door/Entrance : North, East or North-East is good
• As per the auspicious directions of Vaastu shastra the following G+1 floor drawing is made: All dimensions in drawing in “m”.
• 

• The dimensions of building units are :
• Living Room = 3.6 m x 5.1 m
• Kitchen = 2.4mx4.2m
• Puja ghar = 1.2mx1.2m
• Toilet = 1.2mx0.9m
• Toilet + Bath = 2.1mx1.2m
• Bathroom =2.1mx1.2m
• Store room =2.1mx1.2m
• Bedroom = 3.0mx3.0m
• Bedroom= 3.9mx3.0m

• List of structural drawings required to be provided to the site for the construction is as follows :

1. Centre line plan
2. Foundation plan
3. Footing and column layout with the reinforcement details
4. Scheduling of beams and column with detailing of reinforcement
5. Plinth beam layout with reinforcement details
6. Detailed drawing of staircase with all dimensions and reinforcement detail
7. First floor slab layout with reinforcement detailing of slab
8. Elevation and section drawing of building

• Assumed dimensions of structural elements :
• Column sizes :

1. C1 = 225mm x 375 mm
2. C2 = 225mm x 300mm
3. C3 = 225mm x 225mm

• All beam size are = 300mmx450mm
• Slab thickness = 125mm
• Ceiling height/Height of the wall= 3.5 m
• External wall thickness = 300mm
• Internal wall thickness = 150mm
• Indian standard codes which I am going to use for the calculation of loads:
• IS456:2000, Revised 2016 for Reinforced Concrete Structure
• IS875:1987, Revised 2018 ( Part 1 ) for Dead Load
• IS875:1987, Revised 2015 ( Part 2 ) for Live Load
• IS875:1987, Revised 2015 ( Part 3 ) for Wind Load
• Dead Load Calculation :
• Dead load on column:
• C1 = 225mmx375mm:

Dead load on column = Self weight of column

Column height = height of wall + slab thickness = 3.5 + 0.125 = 3.625 m

Column size = 225 x 375 x 3625 mm3 = 0.225 x 0.375 x 3.625 m3

Unit weight of concrete (RCC) = 25 KN/m3

Dead load of column C1 = Total volume of concrete x unit weight of concrete = [0.225 x 0.375 x 3.625] x 25

Self weight of column = Dead load of column =  7.646 KN

As per design, 4 no. of column is provided.

• C2 = 225mmx300mm

Dead load on column = Self weight of column

Column height = height of wall + slab thickness = 3.5 + 0.125 = 3.625 m

Column size = 225 x 300 x 3625 mm3 = 0.225 x 0.30 x 3.625 m3

Unit weight of concrete (RCC) = 25 KN/m3

Dead load of column C2 = Total volume of concrete x unit weight of concrete = [0.225 x 0.30 x 3.625] x 25

Self weight of column = Dead load of column =  6.117 KN

As per design, 11 no. of column is provided.

• C3 = 225mmx225mm

Dead load on column = Self weight of column

Column height = height of wall + slab thickness = 3.5 + 0.125 = 3.625 m

Column size = 225 x 225 x 3625 mm3 = 0.225 x 0.225 x 3.625 m3

Unit weight of concrete (RCC) = 25 KN/m3

Dead load of column C3 = Total volume of concrete x unit weight of concrete = [0.225 x 0.225 x 3.625] x 25

Self weight of column = Dead load of column =  4.587 KN

As per design, only 1 column provided.

• Dead load on beam :

Beam size = 300mmx450mm

Dead load of beam = self weight of beam

We will calculate the load in the form of UDL

Unit weight of concrete RCC = 25 KN/m3

Dead load of beam = Beam size x unit weight of concrete = [0.3x0.45]x25

Self weight of beam = Dead load of beam = 3.375 KN/m

• Exterior wall load on beam :

Wall load on beam = Dead load of wall

Height of wall = 3.5 m

Thickness of exterior wall = 300mm

Unit weight of brick wall = 20 KN/m3

Dead load of wall = [3.5x.030]x20 = 21.00 KN/m

• Interior wall load on beam:

Wall load on beam = Dead load of wall

Height of wall = 3.5 m

Thickness of exterior wall = 150mm

Unit weight of brick wall = 20 KN/m3

Dead load of wall = [3.5x0.15]x20 = 10.5 KN/m

• Self weight of slab

Thickness of slab = 125mm

Self weight of slab = Thickness of slab x unit weight of concrete = 0.125 x 25 m2

Self weight of slab = 3.125 KN/m2

• Self weight of ceiling : 0.25 KN/m2………[as per IS875:1987 part I]

• Self weight of roofing : 0.83 KN/m2….…[as per IS875:1987 part I]

• Floor finish load : 1.00 KN/m2

• Live load calculations:
• Living room=2 KN/m2

• Kitchen =2 KN/m2

• Store room=3 KN/m2

• Toilet =2 KN/m2

• Staircase = 3 KN/m2

• Wind load calculations:

Wind load is calculated for the height of the building is greater than 10m.

Here the height of the building is = 7.25 m  which is < 10m

Hence,

Wind load calculation is not required.
