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

Problem Statement: To sketch a plan of G+1 floor residential building according to Vaastu Shastra and listing down 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 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 :-

PROCEDURE :-

SKETCH OF GROUND FLOOR PLAN :-

Dimensions of Ground Floor plan­ :-

Drawing/Living Room	- 4.76m * 3.8m
Dining Room	- 4.5m * 3.5m
Bed Room	- 4.5m * 4m
Store Room	- 3.5m * 2.8m
Wash Room	- 2.5m * 3.5m
Guest Room	- 4.2m * 3.3m
Kitchen	- 3.2m * 3.8m
Parking Area	- 6.23m * 3.5m
Pooja Room	- 2.8m * 3.5m

SKETCH OF FIRST FLOOR PLAN :-

Dimensions of First Floor Plan­ :-

Bed Room 1	- 4.5m * 4m
Toilet	- 3.5m * 2.5m
Study Room	- 3m * 3.3m
Bed Room 2	- 4m * 3.5m
Terrance	- 13.69m * 4m

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

Calculation of loads :-

1) Dead load Calculations :-

1. 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 first floor

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

Total volume of one Column = 0.3 * 0.3 * 8

= 0.72 m3m3

Unit weight of RCC = 25 KN/m3m3 (as Conforming from IS 875 : Part-1)

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

= 0.72 * 25

= 18 KN

1. B) 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 m3m3

Unit weight of RCC = 25 KN/m3m3 (as Conforming from IS 875 : Part-1)

Dead load of Beam per unit meter length = 25 X 0.135

= 3.375 KN

1. C) Dead load of Slabs :-

Slab is always designed for the span of 1 m2m2. Hence, assume size of slab as 1m * 1m

Thickness of slab = 0.25 m (250 mm)

Unit weight of RCC = 25 KN/m3m3 (as Conforming from IS 875 : Part-1)

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

= 0.25 m3m3

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

= 6.25 KN

1. D) Dead load of Walls :-

Thickness of External/Internal wall = 0.23m (230mm)

Unit Weight of Brick Masonry = 20 KN/m3m3 (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 building, Live Loads are taken as :-

Living/Dining - 2 KN/m2m2

Kitchen - 2 KN/m2m2

Bed Room - 2 KN/m2m2

Wash Room - 2 KN/m2m2

Toilet - 2 KN/m2m2

Store Room - 2 KN/m2m2

Terrace - 3 KN/m2m2

Staircase - 3 KN/m2m2

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.

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

Centre line drawing

Footing and column layout with reinforcement details

Column schedule with reinforcement details

Plinth beam layout with reinforcement details

Each floor beam layout with reinforcement details

Lift pit and head room with reinforcement details

Each Floor plans

Foundation plan

Block plan

Roof slab layout

Column layout

Column sections

Septic tank detail

Overhead water tank detail

Furniture plan

Road drainage plan

Setting out plan

Section drawings of buildings

Plumbing details

Electrification details

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 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

IS 456 :2000 for Reinforced Concrete
