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

Sketched the G+1 Residential plan as per Vaastu Shastra( 2BHK). Dimension of floor area of the Building is

11m x 9m. The total height of the building is 8 m + 3 meter height of staircase room on terrace. The building located in Chennai.

To find the self weight of the structure

1.column

• The size of the column is 300mm x 300 mm.
• Volume of concrete = 3 x 0.3

= 0.09 m^2.

• Unit weight of the concrete = 25 KN / m^3.
• The self weight of the column is

= 25 x 0.09

= 2.25 KN /m.

2.Beam

• The size of the beam is 450 mm x 300mm
• Unit weight of concrete = 25KN/m^3.
• To find the self weight of the beam is

= 0.45 x 0.30 x 25

= 3.375 KN/ m.

3. Slab

• To calculate the self weight of the slab
• The dimension of the slab = 4m x 6m.
• Thickness of the slab = 0.125 m.
• Unit weight of concrete = 25 KN/m^3
• Total volume of concrete is

= 4 x 6 x 0.125

= 3 m^3.

• self weight of the slab is

= 3 x 25

= 75 KN.

4.Brickwork

• The height of the wall is 3.5m
• Thickness of the wall is 230mm
• Unit weight of the brick wall = 20 KN/m^3.
• Self weight of the brick wall is

= 20 x 3.5 x 0.23

= 16.1 KN/m.

To find the live load

• Consider the bed room to determine the live load.
• Let we reference the IS 875 ( part-2) – 1987, for TABLE-1 here mentioned imposed load to various occupancies .
• For bedroom = 2 KN/m^2.
• The room size is 3m x 3.35m
• The area of the room is

= 3 x 3.35

= 10.05 m^2.

• live load of the bed room is

= 10.05 x 2

= 20.1 KN.

To find the wind load of the building , as assumed the height is 10m

• let we take the reference of IS 875:1987( part-3), to calculate the win load acting on the building.
• To determine the design wind speed ( Vz)

Vz = Vb *k1*k2*k3*k4

• Then to determine the basic wind speed (Vb)

To take the reference of Figure 1, to identify the location of building to check the basic wind speed,

Vb = 39 m/s.

• To find propability factor ( k1).

Let take the reference of clause 6.3.1

K1 = 1 m/s.

• To find terrain roughness and height factor (k2)

Let take clause 6.3.2

To analyze the category- 2

K2 = 1m/s.

• To find the topography factor (k3)

Let take clause 6.3.3

K3 = 1 m/s.

• To find the important factor for cyclonic region (k4)

Let take clause 6.3.4

K4 = 1m/s.

• Therefore, design wind speed is

Vz = 39 *1*1*1*1

Vz = 39 m/s.

• Finally, design wind pressure is the formula for,

Pz = 0.6 Vz^2

= 0.6 x 39^2

= 912 N/m^2.
