How to modify wind pressure coefficients ?
In order to change the wind pressure coefficients generated by the 3D wind generator for a specific element/load panel, the user should firstly select the wind data associated to the element/panel in object, thus click on “edit zones”:
At this point the zone editor window appears. By means of this it is possible to edit both the zones geometry as well as the associated pressure coefficients:
To modify zone and/or pressure coefficients the user should switch from “Generate” to “Manual design” or in alternative to “Template according to EC-EN”:
- the “manual design” option allows the user to draw from scratch the wind zones;
- the “template according to EC-EN” option allows the user to operate on a template of zones based on Eurocode.
With both option the user should set the pressure coefficients manually, zone by zone.
TO CREATE NEW ZONES: The “divide” command allows the user to create new zones by vertically/horizontally dividing already existing zones:
TO DELETE EXISTING ZONES: the “join” command allows the user to remove existing zones by merging them with other zones
Finally, the pressure coefficients can be manually input for each zone in the dedicated window:
