Fix the load, and ask what each steel shape costs: the smallest column needs the most steel.
Excel-based P-M interaction analysis tool for rectangular reinforced concrete columns. Supports arbitrary seismic load angles for true biaxial bending via Sutherland-Hodgman polygon clipping. Pure formulas, no VBA. ACI 318 / TW NSC compliant.
This repository documents the ongoing academic capstone project — from process/route selection and thermodynamic validation through to a converged Aspen Plus flowsheet, with further reports to follow on kinetics, column design, heat integration, and final techno-economic evaluation.
