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 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.
Introduction:
* Vastu is the science of direction that combines all the five elements of nature and balance them with the man and the material.
* Vastu Shastra is creating a congenial settings or a place to live or work, in most scientific way taking advantages of the benefits bestowed by the five elements called "Paanchbhootas" of the nature thereby paving the way for enhanced health, wealth, prosperity and happiness in an enlightened environment.
* The world comprises of five basic elements, also known as the Paanchbhootas. They are Earth, Water, Air, Fire and Space. Out of the nine planets, our planet has life because of the presence of these five elements.
VASTU TIPS:
The vastu tips may varies from the facing of house directions. There are four direction of house or building facings. They are
- East facing house/ Building
- West facing house/ Building
- North facing house/ Building
- South facing house/ Building
Working Drawings Required For House Construction Project:
* Architects use drawings as a medium of communicating the design to the client or any related individual involved in constructing a project.
* For a project to be constructed, a final building contract, detailed specifications, and a certain set of working drawings is required, and this set of drawings is referred to as blueprints also. These documents are vital for building construction processes.
* The set of drawings in a working set is provided in a manner such that it corresponds to the building execution phases and procedure.
* List of Drawings that are usually included in a working drawing set are as follows:

Reference point to initiate the construction are inferred from Setting out plan, Surface level markings are depicted on it (Mostly, Ground level being ±00 level for reference)
2.2 Centerline Plans:
* Centrelines are grids that mark the positioning of any structural or non-structural element on-site about a coordinate on the grid.
* Vertical Axes are depicted through Alphabet Notations and Horizontal Axes are depicted through Number Notations, plotting both of these together forms a Grid.
* Centrelines are depicted as Dash-Short Dashed line-type in drawings.

* Centreline Plans are used to generalise a common grid reference for all type of related construction works.
2.3 Floor Plans:
* These blueprints depict the architect’s design as a scaled drawing showing a view from above through an imaginary horizontal sectional plane.
* Architectural floor plans are provided for construction of elements (walls, columns, trenches, etc) through markings and detailed dimensional distance from them concerning the Centreline grid as shown in image.
* These plans also include reference markings of any detail that requires any certain specification according to design.
* These specific details are separately shown for better readability and emphasis.
2.4 Sections and Details:
* Sections are drawings depicting vertical sectional plane projections of the building showing its Interior and Exterior profiles and vertical dimensions of elements.

* Any column on the layout has a certain Grid Coordinate on Centreline Grid that is used as its Column Nomenclature.
3.4 Plinth Beam Layout:
* It is used for marking the Tie beam (Primary element for ‘Earthquake Resistant Structure’) which is used for connecting the columns emerging from the Sub-Structure (structure beneath the ground level) of the building.
* This layout gives the orientation of the Tie Beam to the column and also the Cross-section sizes with specifications of the design.
3.5 Roof, beam and Slab Layout:
* It includes the layout of roof slabs concerning the corresponding beam by the Centreline Grid Markings of Columns-Beams.

Self Weight of Columns and Beams:
a) C1 (500 x 500):
I am Considering the height of the column = 2.7 m
Size of the column, Height of the column = 2.7 m,
Length of the column = 0.5 m,
Width of the column = 0.5 m.
Volume of the concrete = 0.5 x 0.5 x 2.7 m
= 0.675 cu.m
Seif weight of the column = 2500 kg/cu.m x 0.675 cu.m
= 1687.5 kg.
b) C2 (600x600):
Volume of the concrete = 0.6 x 0.6 x 2.7 m
= 0.972 cu.m
Self weight of the column = 2500 kg/cu.m x 0.972 cu.m
= 2430 kg.
c) C3 (300x600):
Volume of the concrete = 0.3 x 0.6 x 2.7 m
= 0.486 cu.m
Self weight of the column = 2500 kg/cum x 0.486 cu.m
= 1215 kg.
d) B1 (200x500):
Volume of the concrete = 0.2 x 0.5 x4.0 m
= 0.4 cu.m
Self weight of the beam = 2500 kg/cum x 0.4 cu.m
= 1000 kg.
e) B2 (300x600):
Volume of the concrete = 0.3 x 0.6 x 4.0 m
= 0.72 cu.m
Self weight of the beam = 2500 kg/cum x 0.72 cu.m
= 1800kg.
Load calculations:
Size of column, Length = 0.45 m,
Width = 0.45 m,
Height = 4.50 m.
Volume of concrete = 0.45 x 0.45 x 4.5 m
= 0.911 cu.m
Weight of concrete = 0.911 x 2400
= 2187 kg
Weight of steel (1%) in concrete = 0.911 x 2% x 7850
= 143.1 kg
Total weight of column = 2187 + 143.1 kg
= 2330.1 kg
= 23.30 KN.
Therefore, the dead load of a column of size,
( 0.45 x 0.45 x 4.5 m) = 23.30 KN.
Considering
Length of brickwall = 1.0 meter
Height of brick wall = 4.0 meter
Thickness of brickwall = 9″= 230 mm
Thickness in meter = 0.23 m
Density of brick wall with mortar is about ranging between 1600-2200 kg/m3
So we consider self weight of brick wall is 2200 kg/m3 in this calculation
A) volume of brick wall
Volume of brickwall = l × b ×h
Length = 1 meter
Width = 0.23 mm
Height of wall = 4.0 meter
Volume = 1m× 0.23 m× 4.0 m
Volume of brick wall = 0.92 m3
B) dead load of brick wall
Weight = volume × density
Dead load = 0.92 m3 × 2200 kg/m3
Dead load = 2024 kg/m
It will be convert into kilo Newton by dividing with 100 we will get 20.24 kN/m
So dead load of brick wall is about 20.24 kN/m acting on beam.
Slab load calculations:
Length of the slab ( Ls) = 4.0 m,
Width of the slab ( Ws) = 4.0 m,
Thickness of the slab( Ts) = 0.25 m.
The self-weight of any RCC structure is calculated by the formula
= [Unit weight × volume.]
As you know, the unit weight of the RCC structure = D =2500kg/cum.
c) Self-weight of the slab:
Weight of the slab
= [unit weight× volume of the slab]
= [ D × ( Ls × Ws × Ts )]
= [ 2500 kg/cum. × ( 4 m × 4 m × 0.25 m. )]
= [ 2500kg/cum. × 4 cum.]
Self weight of the slab = 10000 kg.
= 100 KN.
d) Dead load of walls:
Thickness of external/internal wall = 230 mm
= 0.23 m
Unit weight of brick Masonry = 20 KN/m3
Height of ground floor wall = 4.0 m
Dead load of ground floor wall per unit length of meter = volume of wall per unit length of meter x unit weight of wall.
= 0.23 x 1 x 4 x 20
= 18.4 KN.
Dead load of first floor per meter length = Volume of wall per meter length x unit weight of wall.
= 0.23 x 1 x 3.5 x 20
= 16.1 KN
Total load of wall per meter length = 18.4 + 16.1
= 34.5 KN.
2) Live load calculations:
Living room = 2 KN/M2
Dining = 2 KN/M2
Kitchen = 2 KN/M2
Bedroom = 2 KN/M2
Bath = 2 KN/M2
Store room = 2 KN/M2
Terrace = 3 KN/M2
Stair case = 3 KN/M2.
3) Wind load:
- Basically, wind loads are designed above the height of floor greater than 10 m.
- Assumed height = 7.5 m less than 10 m.
- Hence, no wind load calculations for this problem.
Results:
- The sketch (plan) of G+1 Residential building is prepared with the concept of Vaastu Shastra.
- Assumed the sizes of the structural elements ( column,beam,slab..etc) and accordingly calculated the dead loads of each member.
- The dead load, live load, wind load calculations are done as per the Indian Standard Code. ( IS CODE IS 875:1987, part 1,2&3 for Loads Calculation) ( IS:456:2000 for Reinforced Concrete).
