Construction Technology_Vaastu Shastra & Calculation of loads_Project 2

Sketch a G+1 floor residential plan, according to Vastu 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.

AIM: To prepare a residential plan for G+1 floor according to Vastu Shastra and to caluclate corresponding loads for the components of the house.

Procedure:

Introduction

The total land area considered for the residential plan is 11m X 18m or 198 sq.mts or 4.89 Cents.

The plinth area of the structure is 143 sq.mts or 3.53 Cents.

Plan for ground floor and first floor are shown below

Dimensions of G+1 Floor in this residential plan are

• Dimensions of Master Bedroom and Guest bedroom as 4.3m X 5.91m
• Dimension of Kids Bedroom is 5.13m X 4.14m
• Dimension of Kitchen is 5.13m X 5.91m
• Dimensions of Bath room as 2.43m X 1.49m
• Dimensions of Puja room as 2.75m X 1.2m

Assumed dimensions of other utilities in house

• Thickness of external walls as 0.230m.
• Dimension of each column as 0.3mX0.3m
• Dimension of each beam as 0.3mX0.45m
• Height of each floor as 3m
• Thickness of slab as 250mm or 0.250m
• Thickness of internal walls as 0.115m.
• Dimension of a main door as 1.4m X 2.4m
• Dimension of internal doors as 1m X 2m
• Dimension of window in living room as 3m X 1.5m
• Dimension of window in bedroom as 1m X 1.5m
• Dimensions of ventilator in bathroom as 0.5mX 0.3m

Load Calculations for the residential plan components:

1. Dead Load

Columns:

Total number of columns in the design are “9”

The total load of each column is calculated from the total volume of column and unit weight of concrete

The height of column from ground = Slab thickness X 2 + height of each floor X 2

= 0.250 *2 + 3*2

= 6.5m

Size of the column is 0.3mX0.3m

The volume of each column is 0.3*0.3*6.5 = 0.585 m³

Unit weight of reinforced concrete = 25KN/m³

Dead load due to each column = 25 * 0.585 =14.625KN

Beams:

The dead load of the beam is calculated from the cross-sectional area and unit weight of concrete and the load is calculated in KN/m

The dimensions of beam are 0.3mX0.45m

Unit weight of reinforced concrete = 25KN/m³

Dead load due to beam = 25*0.3*0.45 = 3.375KN/m

Walls:

The dead load of the wall is calculated from the cross-sectional area of brick wall and unit weight of brick wall and the load is calculated in KN/m

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 i.e. floor height difference

Unit weight of brick wall is 20KN/m³

Dead due to external wall = 20*0.23*3 = 13.8KN/m

Dead load due to internal wall = 20*0.115*3 = 6.9KN/m

Wall openings should be removed when total load is being calculated

Wall openings such as doors, windows, ventilators etc.

Brick:

The standard dimension of brick is given as 190 mm x 90 mm x 90 mm

The weight of standard brick is 1.9Kg or 18.632N

Dead load of brick = 18.632N or 0.0186KN

Slab:

The dead load of the slab is calculated from the thickness of slab and unit weight of reinforced concrete and the load is calculated in KN/m².

Thickness of slab considered is 250mm or 0.25m.

Unit weight of reinforced concrete = 25KN/m³

Dead load of slab per m² = 25 * 0.25 *1*1 = 6.25KN/m²

While calculating slab dead load over bathrooms as the slab provided is a sucken slab the thickness of slab is changed to sunken slab thickness. Generally sunken by 200 to 300mm depth.

2. Live Load Calculation

As per Table 1 of IS -875 Part-2, for residential building:

• Living/Dining – 2 KN/m²
• Kitchen - 2 KN/m²
• Bedroom - 2 KN/m²
• Bathroom - 2 KN/m²
• Puja Room - 2 KN/m²
• Terrace - 3 KN/m²

3. Wind Load

The height of the house is 6.5 m.

The wind load acting on the structure is not significant for structures whose height is less than 10 m

Therefore, 6.5m < 10m, Hence Ok no need to design for Wind Load

Result

• The residential plan for a duplex house is made in AutoCAD. The plan consists of 1x Master Bedroom, 1x Guest Bedroom, 1x Kids Bedroom, 1x Living room, 1xPooja room, 1x Kitchen, 1x Sitout, 3x Toilet and a Balcony.
• The residential plan is made by using Vastu Shastra to enhance positive energy in the home.
• The dimensions of beam, column, thickness of wall and slab are assumed as per IS Code.
• For douplex the opening to first floor along with stairs is given as same size of Living room.
