Plastic Analysis in Steel Column to create interaction formulae
Budget: $10 – $30 USD
This small project is suitable for someone who has deep theoretical knowledge about steel structure and plastic analysis, I have already derived a script to get the "exact" curve for pure section control by elementary plastic analysis of cross-section for VKR profile (See VKR Exact.PDF), however, I'm struggling to do the same for an I Beam section, and need help to derive the right formulas for the script, see uploaded Mathcad file (Exact IPE), the curve should look like the figure below:
