Factor of Safety on Laterally Loaded Pile Analysis

Factor of Safety on Laterally Loaded Pile Analysis

Factor of Safety on Laterally Loaded Pile Analysis

(OP)
In analyzing laterally loaded piles, how does F.S. is applied in the design? Is F.S. applied to k value in input data for P-y analysis (e.g. LPILE) or to output values (e.g. Moment or Deflection)? In addition, how much F.S. is generally used for the analysis? Thanks!  

RE: Factor of Safety on Laterally Loaded Pile Analysis

I never use a factor of safety for lateral analysis.  You should make your best estimate of the k value(s) and prepare deflection versus load curves.  Give those the the designer of record and let them determine the impact on their structural system.  The concept of a factor of safety just does not apply.

gre2408 - you are not a newbie to the site so am surprised that you double posted.  This leads to disjointed responses.  Please keep to one post in the geotech groups - most of us read all forums in the group.  Thanks.
