To calculate the dead , live and wind load for RC residential structure and to apply them using TSD
Answer of question No. 1
Aim: Aim is to 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
Introduction: it is ansure a valid model for the analysis and design routines. imposed loads are assigend are according to IS 875 Pat 2.
Procedure:
Step-1
- First we will generate the load cases.
- and generate the load combination.
- we get initial parameters first check and click on next.
Step-2
- Next select dead load at the bottom.
- Now select are from panel load.
- Apply load 1.2 kn/m^2
First Floor:
Now Apply brick load and ground floor and first floor.
select full UDL and 15.6kn/m^2 for ground floor and 20.4kn/m^2 for first floor
Result: Calculated the dead load in design report based on IS code and apply dead load on the model.
Answer of question No. 2
Aim: Aim is to Calculate live load in design report based on IS code and apply dead load on the model.
Introduction:
Loads cases and load combinations are generated assigned for the structure using tekla and thtose loads are important part of tekla structure.
Procedure:
Step-1
work areas without machinery/equipments = 2.5KN/m^2
Work areas with machinery/equipments (Heavy) = 10KN/m^2
Staircase : 4KN/m^2
Toilets : 2KN/m^2
Canteen : 3KN/m^2
Store room : 2.4KN/m^2
Conference room : 4KN/m^2
Meeting room : 4KN/m^2
Office room : 4KN/m^2
Manager room : 4KN/m^2
Corridor : 4KN/m^2
Roof access not provided is taken as : 0.75KN/m2
Procedure:
- Now Click on imposed loads at bottom.
- Select area load in the panel loads.
- Assign loads on the all floor according to the IS 875 part2
Result:Calculated live load in design report based on IS code and apply dead load on the model.
Loads cases and load combinations are generated.
Answer of question No. 3
Aim: Aim is to generate manual wind loading in the design report based IS code as per the following input
- Basic wind speed = 50m/s
- Terrain category 2
Procedure:
Step-1
Wind speed taken as 50m/s
Teerain category is given as 2
Vb = Basic wind speed which is given as 50m/s
Normally basic wind speed is selected from appendix A of code book IS 875 III which is given based on wind speed in various cities
Design wind speed Vz= Vb*K1*K2*K3*K4
Where Vz depends on risk level, terrain roughness, height, size of structure, local topography
K1 = Probability factor
It is taken from table 1 of IS 875 III
Life of structure is taken as 50 yrs and wind speed is given as 50m/s. Based on this K1 =1
K2 = Terrain, height, structure factor which is taken from table 2 = 1.05
K3 = Topography factor which is taken as 1 (θ<3 = 1 and θ>3 = 1 to 1.36)
K4 = Importane factor for cyclonic region K4 is taken as 1.15
Where K4 = 1.3 Structure for post cyclonic importance
= 1.15 Industrial structure
= 1 All other structure
Result: generated the manual wind loading in the design report based IS code as per the following input
- Basic wind speed = 50m/s
- Terrain category 2
