Building Natural Frequency
(OP)
As defined for rigid(>1Hz) or flexible(<1Hz) buidlings in ASCE 7-02, how we can calculate the natural or fundamental frequency of building? thx in advance
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Building Natural Frequency
There is also a more direct approach. Many times, if your structure is a well defined frame system of some kind, some analysis/design software out there have the ability to calculate your major mode frequencies/periods and we have used these. (such as RISA-3D)

I like to add that STAAD Pro will calculate the natural frequency as well. However, I would use an approximate method if all I am interested in is the fn for wind load calculations.
