Create a wind model and wind loads

You can use the Wind Wizard to automate the wind modeling process. Where appropriate, the Wind Wizard uses databases to determine the appropriate wind details for your structure location, and then calculates the appropriate wind loading details according to the selected wind loading code.

Restriction:

The Wind Wizard is not currently available for the Australian AS:1170.2 wind loading code variant.

Once you have defined the wind directions in which you are interested, Tekla Structural Designer automatically calculates the appropriate wind zones on the roofs and walls of your structure. You can set the type of each roof to achieve the correct zoning, and then tailor the zoning to account for particular features in more detail, if you so require.

The wind modeling process can automatically define standard wind load cases for you based on the usual internal pressure coefficients, or you can define the load case information yourself. In both cases, the appropriate wind pressures are calculated on each zone. You can then combine the wind load cases into design combinations as usual.

Note:

The determination of the wind speeds, the pressures, and the zones is rigorous. However, do remember that the final wind loads that are adopted are your responsibility.

Run the Wind Wizard

Note:

You must define at least one wall or roof panel before running the Wind Wizard.

  1. On the Load tab, click Wind Wizard...
    The Wind Wizard opens.
    Note:

    The Wind Wizard varies slightly according to the head code that you are using.

  2. Define the necessary information for the wind model. To go to the next page in the wizard, click Next.
  3. Once you have defined all the necessary information, click Finish.
    Note:

    After running the Wind Wizard, you can review the roof and wall zones for each wind direction.

    After you have created the wind model with the Wind Wizard, you can open a wind view to graphically display the wind zones and loading that apply for a particular wind direction.

Add wind directions

  1. On the Load tab, click Wind Wizard...

    The Wind Wizard opens.

  2. Click Next until you are on the Results page.
  3. Click Add Dir.
  4. Specify the properties of the new wind direction.
  5. Click Finish.
    Note:

    Remember to add new wind load cases and design combinations to incorporate the wind loading for the new direction into your calculations.

Delete wind directions

  1. On the Load tab, click Wind Wizard...

    The Wind Wizard opens.

  2. Click Next until you are on the Results page.
  3. Click the wind direction that you want to delete.
  4. Click Del Dir.
  5. Click Finish.
    Note:

    Remember to update the existing wind load cases and design combinations to remove the details for the wind direction you have deleted from your calculations.

Delete the entire wind model

To delete the entire wind model and start the wind modeling process from scratch, do the following:

On the Load tab, click Delete Wind.

Tekla Structural Designer deletes all the previously defined wind directions and wind load cases.
