Modify wind zones and wind zone loads

In order to view and modify the wind zones and loading that apply to a particular wind direction, you have to open the appropriate wind view. Then, you can modify the wind zones and wind zone loads according to your needs.

Open a wind view

Note: Wind views are only available if you have already created the wind model with the Wind Wizard.

In the Project Workspace, go to the Wind tab.
Right-click the wind direction that you want to view.
In the context menu, click Open View.
Tekla Structural Designer opens the selected wind view, and the Zone Loads tab, which allows you to review wind zone data graphically.

In the Loading list, select the desired wind load case.
Tekla Structural Designer displays the loads that are applied to the structure for this load case in this wind direction.

Modify wind zone loads

On the Zone Loads tab, click Zone Loads.
In the Loading list, select the desired wind load case.
Tekla Structural Designer displays the loads that are applied to the structure for this load case in this wind direction.
In the model, click the wind zone that you want to change.
In the dialog that opens, clear the Use Default Values option.
Modify the values that determine the loads.
Tip: If you want to reduce the net pressure for benecifial loads to zero, select the Beneficial Load option.
To update the zones, OK.

Update wind zone loads

When you change the roofs or walls of your structure, Tekla Structural Designer does not automatically update the changes to existing wind zoning. Updating the zoning is manual because you may wish to make more alterations before you recalculate the zoning.

Once you have completed your changes, incorporating them and recalculating the zoning details is simple. To reinstate the zoning after making changes, do the following:

On the Load tab, click

Update Zones.

The wind zoning calculations run in the background. Once the calculations are complete, Tekla Structural Designer views the new zoning layout for your structure.

Note: If you have defined your own zone layout for any roof or wall, the existing zones will be maintained when you make changes. Make sure to update these zones appropriately.
