I would not expect a vibration analysis to be used for wind, but rather 
a CFD model to simulate the complex shedding and fluid/building 
interactions. Beyond my experience and well beyond my computer 
simulation capabilities.   I have not done a seismic vibration analysis 
since my thesis project, and that was actually a pretty simple modeling 
job (in Visual Analysis, for those interested) of a concrete structure.  
Do those of you running seismic analyses use power spectrum densities 
for random vibrations (random vibration forcing function with defined 
values over specified spectral bands)?  That's how I used to do 
spacecraft...just curious if it translates to buildings. Just don't ask 
me to describe when you have to determine if the stochastic process in 
question is ergotic (there's a "g" in there...stop sniggering).
