pre-stressed stayed columns
hi all -
this is my first post here. i've spent some time looking thru old posts, but nothing:
here's my question-
i'm looking for the formula to calculate the first 2 critical loads for a prestressed column ('diamond' cable stays / central lateral strut / slender column)
i'm working off this paper i have "stability analysis and parametric study of pre-stressed stayed columns" by chan et al, 2000.... really riveting stuff and all! and there is some hand-waiving on the included example problems.
i think the answer may be in 'eurocode' or maybe even in roarks?...both of which i dont have access to right now!
anyone with any direction here would help me out greatly before i get too much more grey hairs on this one.
google seems to be leaving me high and dry on this one.
oh - this is for a fe validation/geometry sheet i am putting together for racing sailboats applications-
thanks in advance -

i think its your terminology.
try these google results for post tensioned (i.e. the stressing is done after fabrication).
thanks for that info csd72 -
this link may better explain the structure i am look at.
