Entering height dependent wind load manually (no simulation)

[Anonymous]

Hi! Is there an (easy) way to enter height dependent wind loads (NB not "wind tunnel simulation")?

For instance, if I have a tall beam structure and want to apply wind loads (calculated by hand according to EC and expressed as kN/m) but want the load value vary with height according to a wind profile similar to that in "wind load simulation"?

Thanks,

Hi @Anonymous

Do you mean the height is varies ?

Colud you please attach sketch for better understanding.

I would like to apply wind load values that vary with height without having to explicitly apply the load on elements for each height level. Like the height profile in wind load simulator but without doing any simulation. If I should apply the wind load shown in the attached figure, I would have to select elements on each height level and apply loads to them level by level. I would like to define a function of height that I could point at and use instead. Is it possible today in some way?

Hi @Anonymous

In addition to the load type indicated by @mustafahesenow (thank you) you may also use contour load on cladding

Ok, I see what you mean - it would work fine if you have some kind of load carrying surfaces which transfer the load to an underlying beam structure. But what if you don't have load carrying surfaces, but just a tall beam framework? Like a beam framework tower or mast on whose beams you wish to apply a height varying line load?

Something like "trapezoidal load" on beams but with the coordinates x1 and x2 not restricted to be defined along the beam but in an more general arbitrary direction, i e z-dir - like a hydrostatic pressure for beams.

Hi @Anonymous

This is what the wind simulation is intended for. If you don't want to use this tool and the wind is acting directly on bar elements of a model (as there are no walls) then you need to apply linearly varying load to columns and uniform load to beams. Both can be defined as rotated matching the wind direction.
