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

AIM:

To prepare a residential plan for G+1 floor according to Vaastu shastra and to calculate corresponding loads for components of house.

• INTRODUCTION TO 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 abundant with powerhouses of energy sources like the sun, wind, fire, moon, water and earth.
• 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 directions 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 Shastra.
• North - Wealth
• South - Dharma
• West and East - Overall prosperity

PROCEDURE:-

• SKETCH OF GROUND FLOOR PLAN:-

• SKETCH OF FIRST FLOOR PLAN :-

• Names of the structural drawings required to be provided to the site for construction are: -

1. Centre line drawing.
2. Footing and column layout as per 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 head room with reinforcement details.
7. Each floor plans.
8. Foundation plan.
9. Roof slab layout.
10. Column layout.
11. Column section layout.
12. Overhead tank layout.

• ASSUMED DIMENSIONS

1. Thickness of external walls - 0.23m.
2. Thickness of internal walls - 0.115m.
3. Thickness of slab =0.25m.
4. Dimensions of each column - 0.3m x 0.3m.
5. Dimensions of each beam - 0.3m x 0.45m.
6. Height of each floor - 3m.

• LOAD CALCULATIONS FOR THE RESIDENTIAL PLAN: -

1. DEAD LOAD CALCULATION:
2. Dead load of Column:

• Dimension of column = 0.3x0.3m

• The height of column from ground = slab thickness x 2 + height of each floor x 2 = 0.25 x2 +3x2 = 6.5m
• Size of column is 0.3m x 0.3m
• The volume of each column is 0.3 x 0.3 x 6.5 = 0.585 m^3
• Unit weight of reinforced concrete = 25KN/m as per conforming from IS 875: Part-1
• Dead load due to each column = 25*0.585=625KN.

2. Dead load of Beams:

• The dimensions of beam are 0.3m x 0.45m
• Unit weight of reinforced concrete = 25KN/m^3
• Dead load due to beam = 25*0.3*0.45 = 375KN/m

3. Dead load of Slab:

• Slab is always designed for the span of 1m or 2m Hence, assume size of slab as 1mx1m.
• Thickness of slab considered as 250mm or 0.25m

• Unit weight of reinforced concrete = 25KN/m^3
• Dead load of slab per m^2 = 25*0.25*1*1= 25KN/m^22

4. Dead load of Walls:

• Thickness of external wall considered here is 230mm i.e., 0.23m
• Thickness of internal wall considered here is 115mm i.e., 0.115m
• Height of each wall is 3m
• Unit weight of brick wall is 20KN/m^3
• Dead load due to external wall = 20*0.23*3=8KN/m
• Dead load due to internal wall = 20*0.115*3= 9KN/m

5. Dead load of Brick:

• The standard dimension of brick is given as 190mm x 90mm x 90mm
• The weight of standard brick is 1.9kg or 18.632N
• Dead load of brick = 632N or 0.0186KN

2. Live load calculation
3. As per Table 1 of IS - 875 part 2, for residential building:
4. living/dining - 2KN/m^2
5. kitchen - 2KN/m^2
6. bedroom - 2KN/m^2
7. bathroom - 2KN/m^2
8. puja room - 2KN/m^2
9. Terrace - 3KN/m^2
10. Wind load calculation

• The wind load acting on the structure is not significant for structures whose height is less than 10m.
• The height of the house is 6.5m.
• Therefore, 6.5m<10m, hence OK, no need to design for wind load.

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 consideration.

References and IS codes used for the design

• IS 875 :1987 (Part 2) for Live load

• IS 875 :1987 (Part 3) for Wind load

• IS 456 :2000 for Reinforced Concrete
