Quick Natural Frequency Estimates
(OP)
I am looking for some quick assessment methods for getting quick estimates of the natural frequencies of building elements from their dead load deflections
Any ideas?
Otherwise possible sources might be useful!

u can use softwares like ANSYS which contains Verification manuals, where certain tutorials or help is given to calculate the natural frequency of structures like simply supported beam etc.

A quick estimation of building natural frequency is 0.1sec per story. Note that this is not the resonance of the building just it's natural frequency to outside input.
