To calculate the dead , live and wind load for RC residential structure and to apply them using TSD

1.Calculate dead load in design report based on IS code and apply dead load on the model

• Finishes of 50mm
• Slab thickness as per the design
• Brick wall load
• Roofing load

finish load=0.5*24=1.2kN/m2

slab load will be generated within the software

brickwall+cement plaster thickness 230mm,

brickwall loading-

• GL-1st floor-0.23*20*3.2=14.72kN/m3
• same for 1st floor-roof level
• roof level-(paraphet wall height is 900mm and thickness 155mm)=0.155*0.9*20=2.79kN/m3

roofing load-finish floor-1.2kN/m2

2.Calculate live load in design report based on IS code and apply dead load on the model

As per IS 875:part 3,live load for Rc offcie building are :

• office=3 KN/m^2

• reception=3 KN/m^2

• meeting room/conferece room-4 kN/m3

• equipment room =10 KN/m^2

• Toilets=2 KN/m^2

• Store room = 5 KN/m^2

• Staircase =3=4 KN/m^2

• Lobby =3 KN/m^2

• cooridor=4 KN/m^2

• Roof (accessible)=1.5 KN/m^2

3.Generate manual wind loading in the design report based IS code as per the following input

• Basic wind speed = 50m/s
• Terrain category 2

As per IS-875:part3,

GIVEN:basic parameter

• basic wind speed-39 m/s
• terrain category-2
• probable design period of building-50 years
• class of strcuture -A

dimensions of the building-

• greater horizontal dimension-19.225m
• lesser horizontal dimension-10.7m
• height of the building-6.4m
• width of frmae-1,grid A to B-6m

ratio of wall and roof-coefficient

• wall-l/w=1.8
• wall-h/w=0.6
• roof-h/w=0.6

topography factor,k3-1

risk co-efficient,k1-1(50 years)

up to 10m height,terrain factor(k2)-1

important factor for cyclonic,k4-1.15

design wind speed,V2=Vb*k1*k2*k3*k4

39*1*1*1*1.15=44.85 m/s

design wind pressure,Pz=0.6*vz^2/1000

0.6*44.85*44.85/1000=1.207 kN/m2

internal pressure cooefficient=0.5(20% opening as per c;ause 6.2.3.3)

internal pressure cooefficient=-0.5

wind loading calculation-

wind load acting along X-direction(face A)

wind loading along X-direction(face B)

wind loading along X-direction(face C)

wind loading along X-direction(face D)

wind load in Y directions-

wind load acting along Y-direction(face A)

wind load acting along Y-direction(face B)

wind load acting along Y-direction(face C)

wind load acting along Y-direction(face D)

AIM:Based on the above calculation apply the loadings on the model.

PROCEDURE:

• go to load toolbar,define load cases.

• generate load combinations.
• for dead load,finish load-select area load and enter 1.2kN/m2.

• for brickwall load,select full UDL/point UDL and enter the repective value.

• for live load,select area load and enter value as per IS code book.

• for wind loads,first add wall panels.

• select area load and respective direction of building face,enter the value an select on wall panel.

RESULT:

The calculated loads are applied on the model successfully.
