Cable relaxed length

[PBezaitis]

Hello,

I am working on a suspension bridge and I have optimized the prestress forces for the cables following the procedure shown in a video by Jürgen Bellmann.
My question is: how exactly does the corresponding command in the Results window work?

Is there any documentation or manual that explains how SOFiSTiK calculates the relaxed cable length during this process?

Thank you.

That will simply be a back-calculation from ε = σ / E. And ΔL=ε⋅L0​.
