Lateral loading analysis in piles
(OP)
Hi, when you analyze piles under lateral loading, do you consider the axial force applied to the pile? I understand that there are axial-moment interaction curves, but most of my analysis have been done assuming axial force is zero. I am just curious to know what is your approach for lateral loading analysis. As always, thanks for your input !!

In my case, commonly, geotechnical investigations are done at earlier phases of the design, so I do not have lateral loading info from the structural, so I try to back-calculate the allowable lateral force for a specific lateral displacement while I am not exceeding the crack moment of the pile (pre-stressed concrete piles). As you mentioned, I noted that for pre-stressed concrete piles, the balanced point gives larger moments than if I assume axial load equals zero, then I started to think that in reality the pile is subjected to axial and lateral forces simultaneously, so considering the axial load as zero for lateral loading analysis maybe too conservative.

At the time of your analysis you do not have any more information to go off of. What some of the geotechs around here do is give the conservative value based off of similar assumptions to yours, and then add a clause that if more capacity is required that the geotech should be contacted and they will examine it on a case by case basis.

If foundation pile, no.
