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

AIM

1. 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.
2. 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.

PROCEDURE

Below images show the plan of G+1 floor residential building according to Vaastu Shastra.

1. The list of structural drawings that is required to be provided to the site for construction are as follows:

1. Centre line drawing
2. Footing and Column layout with reinforcement details
3. Column Schedule with reinforcement details
4. Plinth beam layout with reinforcement details
5. Ground floor Slab layout with reinforcement details
6. First floor Slab layout with reinforcement details
7. Roof Slab Layout with reinforcement details
8. Staircase drawing with reinforcement details.

2. Assume the sizes of the structural elements as follows.

• All columns are 300mm x 300mm.
• All beams are 300mm x 450mm.
• Slab thickness if 125mm.
• The height of the wall is 4.5m.

i) Calculation of Dead Load:

Dead load of column = Unit weight of concrete x Total volume of column

= 25 x 0.3 x 0.3 x 4.5

= 10.125 kN

Dead load of beam = Unit weight of concrete x Total volume of beam

= 25 x 0.3 x 0.45

= 3.375 kN/m

Dead load of slab = Unit weight of concrete x Total volume of slab

= 25 x 0.125 x 1 x 1

= 3.125 kN/m2

Dead load of wall = Unit weight of brick wall x Total volume of wall

Here,

Thickness of wall = 0.23 m

Unit weight of brick wall = 20 kN/m3

= 25 x 0.23 x 20

= 115 kN/m

ii) Calculation of Live Load:

The Live load calculations are based on IS 875 (Part-II).

a) Ground Floor: For all rooms including Bath rooms & Kitchen

As per IS code,

UDL = 2.0 kN/m2

Area = 104 m2

Therefore,

LL = 104 x 2

= 208 kN

b) Ground Floor: For Staircase, Corridor and Verandah

As per IS code,

UDL = 3.0 kN/m2

Area = 52.5 m2

Therefore,

LL = 52.5 x 3

= 157.5 kN

c) First Floor: For all rooms

As per IS code,

UDL = 2.0 kN/m2

Area = 72 m2

Therefore,

LL = 72 x 2

= 144 kN

d) First Floor: For Staircase, Corridor and Balcony

As per IS code,

UDL = 3.0 kN/m2

Area = 84.5 m2

Therefore,

LL = 84.5 x 3

= 253.5 kN

RESULT

The above G+1 floor residential plan is according to Vaastu Shastra and the required list of structural drawings that need to be sent to site for construction are listed. The load calculation is done as per IS code.
