Re: Seismic design of pole building

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

I don't have answers to your seismic questions, but I would suggest that
you warn your client that their building may vibrate during moderately high
winds.  Pole structures seem to do that.

Check out the Harbor House at Pete's Harbor in Redwood City on a blustery

Also, was a soil report prepared for this site?  This will also affect the
performance of the pole system.  Some geotechs provide two parameters for
passive pressures; one for minimal displacement at the ground level and one
for 1/2" movement at ground level.
