gust factor - answers

[Subject Prev][Subject Next][Thread Prev][Thread Next]

With no responses, I bit the bullet and did it myself. 

Changing parameters in the EXCEL spreadsheet, I was able to find the answer to the question I addressed to the List. 
The ASCE 7 value for gust factor for a very flexible and tall (48-ft) post may be reasonably assumed at 0.9 (Exposure B). 
The code algorithm does not appear sensitive to changes in rigidity (natural frequency), but reacts to switching to Exposure C.
