Moment magnification method for prestressed piles
Moment magnification method for prestressed piles
(OP)
Hi all,
By ACI moment magnification factor = Cm/(1-Pu/0.75Pc), where Pu - factored axial load, Pc - critical buckling load. In case of prestressed piles, shall Pu include prestressing force?
Thank you for your thoughts!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

There's no magnification of moment once the pile is in the ground, correct? It's braced by the surrounding soil?
