Buildings with helical piles

[rsab]

I need to gather information about buildings that have helical piles as part of their foundation systems and outstand an earthquake (regardless of there location). Does anyone know how can I get these information?

Some good information sites on helical piers I found during my own research recently. Some of these sites have case histories and seismic performance information.

--- they have info on "seismic retrofitting" for micropiles

You should also contact the people at Chance who are one of the leaders in helical pier installations and can probably get you the info you need.
