To calculate wind load for industrial steel structures and to apply it by using TSD

1.Aim:

To generate manual wind loading in the design report based IS code as per the following input

• Basic wind speed = 39m/s
• Terrain category 2

Procedure:

• Open Excel sheet for calculation and open TSD file which created early to check dimension of the building.
• 
• Refer code IS 875 Part-3 2015 for,
• 
• For K_1,
• 
• For k_2,
• 
• K₂ factor is,
• 
• For k_3,
• 
• For k_4,
• 
• Internal pressure coefficient- 7.3.2.2
• 
• For external co-efficient, Refer Table 5
• 
• With the above reference, Enter the value in excel for calculation.
• 
• Wall loading calculation:
• 
• Roof loading calculation:
• Refer code IS 875 part 3
• 
• 

Result:

Hence, the calculation is done by refering IS 875-2015  Part-3.

2.Aim:

To apply the loadings on the mode from the above calculation

Procedure:

• For applying wind load,
• In TSD file, go to Load -> Load cases -> add to add the main load cases
• 
• Click ok
• Y- direction:
• Select the load case, Wind +Y +Cpi in status bar and go to 3D view.
• Go to load -> Area load and select below property in property window and select the wall panel in face A.
• 
• Go to face B and apply load as mentioned in the table.
• 
• Go to face c and D and model wall panel as shown below.
• 
• 
• Go to face C and apply load as mentioned in the table
• 
• Go to face D and apply load as mentioned in the table
• 
• Change the load case to +Y -Cpi and follow the same procedure.
• Face A:
• 
• Face B:
• 
• Face C:
• 
• Face D:
• 
• X-direction:
• Take X direction front side as face A and apply load as applied before.
• 
• Face B:
• 
• Face c:
• 
• Face D:
• 
• Go to +X -Cpi and apply the load by following the same procedure
• 
• Face B:
• 
• Face c:
• 
• Face D:
• 

• Roof loading:
• Go to 3D view
• Face EF:
• Select load as +Y +Cpi and give the loading on roof as shown below
• 
• Face GH:
• 
• Select load as +Y -Cpi and give the loading as shown below
• Face EF:
• 
• Face GH:
• 
• Select load as +X +Cpi and give the loading as shown below
• Face EG:
• 
• Face FH:
• 
• Select load as +X -Cpi and give the loading as shown below
• Face EG:
• 
• Face FH:
• 
• Result:
• Click validate to validate the model.
• 
• Hence the loading is applied to the wind panel and roof panel by the above steps.

3. Aim:

To generate wind loading using wind wizard on a separate model.

Procedure:

• Open the TSD file for steel building and save as in different folder for wind wizard analysis
• Select Load -> Wind wizard and select the following option and click next
• 
• 
• Click next and select the below setting.
• 
• Click next which will show the Design wind pressure.
• 
• It shows Wind pressure as per the degree
• 
• Click finish.
• Select load -> load cases and enter the cases.
• 
• Click analyze-> first order -> combination -> ok
• 
• Results:
• Click validate to check the model.
• 
• Select the load combination in the status and click the review view.
• 
• Select the result view in the status below to see the results.
•
