use of stability functions in design
 
use of stability functions in design
i completed my msc in structures a year ago and part of my course was learning to use stability functions to calculate end-moments for axially loaded columns.
however, i have yet to use stability functions in my designs and the only reference i could find on the functions was in coates, coutie and kong.
has anyone any examples or references of frame design using stability functions, please?
check out our whitepaper library.
i dont think they use stability functions now because of secondary structural analysis. i re

thanks for the reply. may i ask what secondary analysis is please. i was taught stability functions two-years ago so i assume the university had something in mind - or were they only filling in a gap in the syllabus.

my understanding is that stability functions are more accurate than most analysis methods but i am not aware of any significant software that uses this approach. i also used them in grad school to solve some problems and i was also asked to compare my answers to the values shown in the column nomographs everyone has seen. i was quite surprised to learn how close these nomographs are. i don't know where you will find folks that are interested in being that accurate to use stability functions. good luck.
