Confinement factor

[obaidullah khan]

if i adopt e.g manders concrete model the program can calculate confinement factor for me, unconfine strength for me in the section property options these two things are available thats nice but what about the confine/core strength of my section i am unable to find confine strength of my section.is SStruct is capable of showing graphs/values of confine and unconfine model/section just like ETABS?

You can specify "Output Stresses and Strains" at selected points in the pre-processor "Analysis Output" tab and then plot stress versus strain for those points in the post-processor. You need to select the appropriate points in order to make the results available in the output. I ran a trial case in which I specified one point in the outer edge of the core and another point next to the first one, but on the cover concrete. The subsequent plots for the two points show the larger stresses and strains in the core relative to those in the shell. Best of luck with your work.
