To calculate wind load for industrial steel structures and to apply it by using TSD
AIM :
- Generate manual wind loading in the design report based IS code as per the following input
- Basic wind speed = 39 m/s
- Terrain category = 2
PROCEDURE :
- First calculate load combination
RESULT:
- Calculations are done for the wall panel
2) Based on the above calculation apply the loadings on the model
AIM :
- To determine based on the above calculation apply the loading on the model
PROCEDURE :
- Open TEKLA structural software and open week 4 file
- Select load tab, in that select load cases and add new load cases
- Now as per value apply the load
- Frame 1 = Wind+y+cpi = 0.253 kN/m^2
- Apply load on Frame 5 = Wind +y+cpi = -0.951 kN/m^2
- Negative value means wind acting away from the wind panel
- Apply load on face 1 = wind+y-cpi = 1.52 kN/m^2
- Apply load on face 5 = wind+y-cpi =0.317 kN/m62
- Apply load on face C =wind+y+cpi = -1.394 kN/m^2
- Apply load on face D=wind+y-cpi = -0.127 kN/m^2
- Now we will apply load of -y
- All loading will be similar just the direction of wind is changed
- Frame 5 = wind-y+cpi = -0.253 kN/m^2
- Apply load on Frame 1 - wind-y+cpi = 0.951 kN/m^2
- Apply load on Frame 5 = wind-y-cpi = -1.521 kN/m^2
- Apply load on Frame 1 = wind-y-cpi = -0.317 kN/m^2
- Apply load on frame D = wind-y+cpi = 1.394kN/m^2 on global X axis
- Apply load on frame A=wind-y-cpi = 0.127 kN/m^2 on global X axis
- Apply load on face C = wind+y-cpi = 0.317kN/m^2
Now apply wind load on roofs and take roof angle as 25 degree
- From IS 875 part 3 table 3 clause 6.2.3.2
Now apply roof load on PQ
- Frame 2 =wind+y+cpi = -1.204 kN/m^2
- Apply load on frame 2= wind+y-cpi = 0.063kN/m^2
Roof XY
- Apply load on frame 1 = wind+y-cpi = 0 kN/m^2
Roof PQ
- Apply load on frame 1= wind -y+cpi = 1.204kN/m^2
- Apply load on frame 1=wind-y-cpi= -0.063 kN/m^2 on roof PR
- Apply load on frame 2 of roof XY = wind -y+cpi = 1.267 kN/m^2
- Apply 0 kN/m^2 on roof XY of frame 2
RESULT :
3) On a separate model generate wind loading using wind wizard
Aim :
- On a separate model generate wind loading using wind wizard
PROCEDURE :
- Open the file
- Open load cases in load tab
- Delete all load cases and set only default load cases
- On load panel select wind wizard and select the cyclonic effect
- Check all the details of the building like wind speed, height of building affected by wind and also k1 and k2 factor
- Select terrain category as open terrain scattered obstructions
- Fetch distance is 10
- Click next then select topography and then next
- After that, it shows resultant wind pressure
- Click on Finish
- Now click on wind load cases
- Now all the loads are applied. and click on validation to check for errors.
