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

- All columns are 230mm x 300mm
- All beams are 230mm x 300mm
- Slab thickness is 125mm
- The height of the wall 4.5m

DEAD LOAD :

i) Dead Load of Column:

Column of size 0.23m*0.30m

Column height=9m

Total volume of concrete = 0.23*0.30*9=0.621m^3

Unit weight of concrete = 25KN/m^3

Deat load of column = 25*0.621=15.52KN

Here provide total number of column = 12

Total dead load of column = 12*15.52=186.24KN

ii Dead load of Beam:

Beam of size o.23*0.30m

Beam lenght =5m

Total volume of beam = 0.23*0.30*5=0.552m^3

Unit weight of concrete= 25KN/m^3

Here we provide total number of column =12

Dead load of Beam = 25*0.552=13.8KN/M

Total dead load of beam =13.8*12=165 KN/M

iii) Slab 1 and 2 Load:

Thickness of slab = 125mm

Unit weight of concrete = 25KN/m^3

Self weight of slab= Thickness of slab*Unit weight of concrete

= 0.125*25=3.125 KN/m

Total calculatio of slab 1 and salb 2= 3.125*2=6.25 KN/M

iv) Calcualation of the wall load

Height of wall = 4.5m

Thikness of the wall = 230mm

Unit weight of Brick wall = 20KN/m^3

Deat load of wall = 20*4.5*0.23 =20.7KN/m

LIVE LOAD:

The loading design detail to taken fron IS 874: PART-2

Here we taken live load of residential building for code using IS875 part-2

we consider Uniformly Distributed Load

i) All rooms and kitchen = 2.0 KN/m^2

ii) Toilet and bath rooms =2.0KN/m^2

iii) Staircase, and porticos = 3.0KN/m^2

WIND LOAD:

Design wind pressure is calculated using the expression

Pz=0.6 Vz^2

where, Pz= wind pressure @ height z, in N/m^2

Vz= Design wind speed @ height z, in m/s

Vz is calculated using the formula

Vz=Vb*k1*k2*k3*k4

where, Vb= Basic wind speed

k1= Probability factor (Risk Co-efficient)

k2= Terrain roughness and height factor

k3= Topography factor

k4= Impo rtance factor

Vb=Basic wind speed we considereing general building for chennai thats is for 50 years return period is 50m/s then we taked value of 1.0

k1 factor value we taked from Table-1

K1 = Probability factor (risk co-efficient) = 0.1

k2 = Terrain riughness and heught factor,

we take category 1 exposed terrain with few or no obstruction and in which the average is less than 1.5 m

we taken value of building 10m = 1.05

k3 = the value of k3 is confined in the rang of 1.0 to 1.36= 1.0

k4= 1.00

Vz=Vb*k1*k2*k3*k4

Vz= 50*0.1*1.05*1.0*1.0=7.5m/s

Design wind load is = Pz=0.6 Vz^2

Pz=0.6*7.5^2= 9 N/m^2
