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

Question 1.

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

Basic wind speed = 39m/s

Terrain category 2

Answer -

Procedure -

First we have to open the MS Excel to enter the values used for calculations.

Next we have to obtain the required standard values from the IS codes.

We have to have dimensions of our projects.

Assume the wind speed as 39 m/s.

Next we have to calculate the wind directions in both X and Y direction.

We have to calculate

1. External Pressure Coiffients

2. Internal Pressure Coiffients

3. Net Pressure Coiffients

4. Design wind pressure for wall

5. Loading to be applied on the wall

Results -

Thus after we obtain all the above values, we can start our manual calculations.

Question 2.

Based on the above calculation apply the loadings on the model

Procedure -

First open the file for which we have to apply the wind loads.

Go to the load cases and add 8 wind loads.

Wind + Y + cpi

Wind + Y - cpi

Wind - Y + cpi

Wind - Y - cpi

Wind + x + cpi

Wind + x - cpi

Wind - x + cpi

Wind - x - cpi

Next with the help of the manual loads which were calculated earlier, apply the loads on the structure.

Adjust the direction to global Y for face A and B.

Adjust the direction to global X for face C and D.

Adjust the direction to global Z for the roof components.

For all the sides we have to apply both +cpi and -cpi values.

With this all the loads can be applied on the strcture.

Result -

With above calculated loads, now they applied on the structure.

Question 3.

On a separate model generate wind loading using wind wizard

Procedure -

Open a new file to start the drawing.

Create construction levels with required heights.

Go to manage property sets and create new concrete columns, steel columns and beam.

Add concrete columns and steel columns

Now add steel beam from ground floor to first floor.

Add dead and live loads on the structure.

Create frames on the structure.

Now design wall and roof panels for the structure.

Click on wind wizard option.

Select consider topography and consider cyclonic effect options and click on next.

Next give the dimensions and enter the wind speed value as 39 m/s and select all general buildings and industrial structure.

Select the terrain category and enetr the fetch a distance value as 10 m and click on next.

The results will be appeared and click on next.

At last click on finish option.

Now we are successfully in applying the wind loads using wind wizard tools.

Results -

With above steps we can complete wind analysis using wind wizard tool for automatic calculations.
