One calculation error in a portal frame doesn't just waste your time — it gives you the wrong column size, wrong connections, and a structure that doesn't perform as designed. This video introduces the Frame Formulae Design Toolkit — a complete Excel workbook with 38 standard portal frame load cases, built to eliminate the human error that comes from manual constant-by-constant calculation.

✅ Rectangular Portal Frames — Fixed & Hinged Base (18 cases)
✅ Gable Portal Frames — Fixed & Hinged Base (20 cases)
✅ Gravity, wind, crane gravity & surge loads — all covered
✅ Live stiffness constants (k, N1, N2, φ, m, B, C) — no manual chain calculation
✅ All joint moments (MA, MB, MC, MD/E) and reactions auto-linked to your inputs
✅ Accurate crane bracket geometry diagrams — a, b, c dimensions clearly shown
✅ Metric units (m, kN) throughout — site-ready
