Spectrum analysis - force spectrum

[Ronald286]

Hello,

Is it possible to define force spectrum in RSA? 

[Pawel.Pulak · Accepted solution]

No, it is not possible.

Spectrum analysis available in Robot concerns movement of soil and is related to seismic effects.

Your reference added to the already existing wish of such feature:)

And just a side question related to force spectrum: for what type of loads would you like to use such analysis? wind? something else?

this is what i thought.

Yes, exactly for wind load. At the moment it is super complicated to analyze high slender structures(with non symetric cores position), sensetive to wind dynamic loads(with small natural frequenicies). Present codes(eurocode, russian code) give a reference to spectrum analysis.
