Sketch a G+1 residential plan according to Vaastu Shastra and Calculation of Loads as per IS code
I. AIM: -
- 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
- Calculate the individual corresponding loads from the members as per IS code.
II. INTRODUCTION: -
What is Vastu 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
- Four cardinal directions North, South, East and West
- Four intercardinal directions North-east, North-west, South-east and South-west
- Each direction signifies an aspect of life and is governed by various gods
- North-Wealth
- South - Dharma
- West and East - Overall prosperity
Favourable directions as per Vastu Shastra:
- South-east is the best
- North-east to be avoided
- South-west is the best KILL LYNC
- North-east to be avoided
- North-west is the best
- North-east to be avoided.
- South-west is the best
- North-west is the best
- North-west is the best
- West is the best
- North-east is the best
- South-west to be avoided
III. List of drawings that is mandatory to be provided to the site: -
- Centre line drawing
- Footing and Column layout with reinforcement details
- Column Schedule with reinforcement details
- Plinth beam layout with reinforcement details
- First-floor beam layout with reinforcement details
- First-floor slab layout with reinforcement details

IV. CODES used for different Loads Calculations: -
| IS 875 Part 1 1987 | Dead Load |
| IS 875 Part 2 1987 | Live Load |
| IS 875 Part 3 1987 | Wind Load |
V. Assumptions: -
- All columns are 300 mm x 300 mm
- All beams are 300 mm x 450 mm
- Slab thickness is 125 mm
- The height of the wall is 4.5 m
VI. Drawings: -


Notes: -
- Plot Area = 10.725 m X 7.31 m
= 78.399 m^2.
- All dimensions are in meter.
- Plan is not according to the dimension.
VII. LOAD CALCULATIONS: -
Given: -
- All columns are 300mm x 300mm
- All beams are 300mm x 450mm
- Slab thickness is 125mm
- The height of the wall is 4.5m
To find: - Dead load, Live load, and Wind load for the proposed given plan
Solution: -
From the plan we have,
| Number of columns | = | 13 |
| Number of beams | = | 19 |
| Height of the wall | = | 4.5 m |
| Slab thickness | = | 125 mm = 0.125 m |
A. Dead Load calculation of column: -
- Column size = 300mm x 300mm = 0.3m * 0.3m
- Height of column = Taking as the height of the wall = 4.5 m
- Volume of column = 0.3 * 0.3 * 4.5 = 0.405 m^3
- Unit Weight of RCC = 25 KN/m^3 (As per IS 875 Part 1 1987)
Therefore,
Dead load of 1 column = 0.405 * 25
= 10.125 KN
Dead load of 13 columns = 10.125 * 13
= 131.625 KN
B. Dead Load calculation of beam: -
- Beam size = 300mm x 450mm = 0.3m * 0.45m
- Unit Weight of RCC = 25 KN/m^3 (As per IS 875 Part 1 1987)
Therefore,
Dead load of 1 beam = 0.3 * 0.45 * 25
= 3.375 KN/m
Dead load of 19 beams = 3.375 * 19
= 64.125 KN/m
C. Dead Load calculation of Brick wall: -
- Wall height = 4.5 m
- Unit Weight of Brick masonry = 20 KN/m^3 (As per IS 875 Part 1 1987)
Let the thickness of the wall be 250 mm = 0.25 m
Therefore,
Dead load of 1 Brick wall = 0.25 * 4.5 * 20
= 22.5 KN/m
D. Dead Load calculation of Slab: -
- Slab Thickness = 0.125 m
- Unit Weight of RCC = 25 KN/m^3 (As per IS 875 Part 1 1987)
Therefore,
Dead load of Slab = 0.125 * 25
= 3.125 KN/m^2
E. Live Load calculation of the given House Plan: -
Intensity of different Live Loads as per IS : 875 (Part 2) - 1987
| S. No. | Occupancy Classification | Uniformly Distributed Load (UDL) (KN / m^2) |
| 1. | Bedroom | 2.0 |
| 2. | Kitchen | 2.0 |
| 3. | Living / Dining | 2.0 |
| 4. | Store room | 3.0 |
| 5. | Bath | 2.0 |
| 6. | Terrace | 2.0 |
| 7. | Staircase | 3.0 |
F. Wind Load calculation of the given House Plan: -
Since, the Height of the building is below 10 m
So, as per IS : 875 (Part 3) - 2015
No Wind Load calculation is required.
