Wind loading can be modeled in Tekla Structural Designer in a variety of ways:
The Wind Model method requires you to first 'clothe' the structure in wind and roof panels and then run the Wind Wizard to create wind zone loads that are subsequently decomposed to the structure during analysis.
By manually applying wind loads you avoid the requirement to construct a wind model. For this approach, loads can either be applied directly to the structure as Panel, Member, or Structure loads; or they can be applied as simple wind loads, which are subsequently decomposed to the structure during analysis.
For tall buildings you may require the assistance of wind specialists to perform wind tunnel testing. The information they supply can then be imported in the form of diaphragm loads.
Note: The Wind Model method is not currently available for the AS:1170.2 wind code variant.
