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

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.

PLAN

All walls are 9" or 230mm thick. All Columns are 230 x 450 mm, FLoor height is 3m(Excluding slab thickness).

AT GROUND LEVEL

Height of floor is 3m, the wall load / Dead load on plinth Beams is as follows

Height of wall = 3.0 - 0.45 Or 3.0-0.6 = 2.55 to 2.4 m

wall thickness = 0.23m.

Density of Brick masonry wall = 20 Kn/m2

Wall load = 2.55 * 0.23 * 1 * 20 = 11.73 kN/m

Wall load = 2.4 * 0.23 * 1 * 20 = 11.04 kN/m

Density of Reinforced Concrete = 25 kN/2

Dead Load of Beams : 0.23 * 0.45 * 1 * 25 = 2.58 kN/m2

GROUND FLOOR SLAB / BEAMS

LIVE LOAD on Slab : Dead Load of Slab :

As per IS -875 Part-2, for residential building: Density of Reinforced Concrete = 25 kN/2

Living/Dining - 2Kn/m^2

Kitchen - 2Kn/m^2 For 150 mm thick slab , DL = 0.15 * 1 * 1 * 25 = 3.75 kN/m2

Bedroom - 2Kn/m^2 For 200 mm thick slab , DL = 0.15 * 1 * 1 * 25 = 5 N/m2

Bathroom - 2Kn/m^2

Terrace - 3Kn/m^2

Balcony - 3Kn/m^2

Load on Beams

Since Floor height is 3m, the wall load Beams is as follows

Height of wall = 3.0 - 0.45 Or 3.0-0.6 = 2.55 to 2.4 m

wall thickness = 0.23m.

Density of Brick masonry wall = 20 Kn/m2

Wall load = 2.55 * 0.23 * 1 * 20 = 11.73 kN/m

Wall load = 2.4 * 0.23 * 1 * 20 = 11.04 kN/m

Dead Load of Beams

  • For 230*450 Beams = 0.23 * 0.45 * 1 * 25 = 2.58 kN/m2
  • For 230*600 Beams = 0.23 * 0.60 * 1 * 25 = 3.45 kN/m2

FIRST FLOOR SLAB / BEAMS

LIVE LOAD on Slab , Terrace - 3Kn/m^2

Dead Load of Slab : For 150 mm thick slab , DL = 0.15 * 1 * 1 * 25 = 3.75 kN/m2

For 200 mm thick slab , DL = 0.15 * 1 * 1 * 25 = 5 N/m2

Load on Beams

Since Floor height is 3m, the wall load Beams is as follows

Height of wall = 3.0 - 0.45 = 2.55

wall thickness = 0.23m.

Head room Wall load = 2.55 * 0.23 * 1 * 20 = 11.73 kN/m

Dead Load of Beams

  • For 230*450 Beams = 0.23 * 0.45 * 1 * 25 = 2.58 kN/m2
  • For 230*600 Beams = 0.23 * 0.60 * 1 * 25 = 3.45 kN/m2

HEAD ROOM DETAILS

LIVE LOAD on Slab , Terrace - 1.5 Kn/m^2

Dead Load of Slab : For 150 mm thick slab , DL = 0.15 * 1 * 1 * 25 = 3.75 kN/m2

Dead Load of Beams

  • For 230*450 Beams = 0.23 * 0.45 * 1 * 25 = 2.58 kN/m2

COLUMN LOADS

ALL COLUMNS are of size 230*450mm

Height of column = 3 + 0.15 + 3 + 0.15 = 6.3m

Height of column at Head room = 9.45m

Dead load of column of ht 6.3 = 0.23 * 0.45 * 6.3 * 25 = 16.301 kN

Dead load of column of ht 9.45 = 0.23 * 0.45 * 9.45 * 25 = 24.451 kN

WIND LOAD : As per IS 875 part 3, wind loads can only be calculated for a structure of height 10m and above. since the above structure is 9.5 in height, wind loads are not aplicable.
