Hi there,
ETABS non-iterative P-Delta analysis generates smaller second-order moment than the one from iterative P-Delta analysis. Also it seems that the non-iterative P-Delta cannot consider local P-small delta. Please share your experience. Thanks.

the non iterative consider ur dead loads as ur vertical loads only. That's why u have smaller second order moments
generally, it is used as a preliminary design since it is faster. I never use it
