Factor of Safety on Laterally Loaded Pile Analysis

[gre2408]

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!

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.
