Week 3 Challenge
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 loadingGL-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,

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
