Dear,
In the Load Items - Wind load dialog box, there is an check box for "open structure".
If the Wind load is already defined in Load Definition, as an Trussed tower, Lattice framework or an open building structure, what effects will have this check box in the load item?
Best regards,
You still need to check the Open Structure check box when applying the load on the structure through the load case. The selection of the structure type within the wind definition only influences the generation of the intensity vs height data. How the generated load is applied on the structure, is determined by the parameters you specify within the load case.
