I have a query related to Vortex shedding.
As per client's requirement in one of the project, Dynamic wind analysis is to be carried out for columns.

As per our understanding, Vortex shedding option has to be checked for columns. Please confirm that our understanding is right.

But if i check the column for vortex shedding in PVELITE, It gives very unrealistic result, even the anchor bolts are failing with twice of the bolt dia than the one which is used without selecting this option.

Please clarify,
1.when the vortex shedding option is to be used ? and
2.How to perform Dynamic wind analysis in PVELITE?

Please notice that the columns have equipment supported platforms & ladders along it's length which may resist the formation of vortex shedding.

Thank You.
