👉Structural Frame Analysis 🏗️
🔖This shows a moment distribution method applied to a 2D portal frame (3 bays × 1 story).
🧷Key steps
🪧Fixed-end moments for each 8m span under 2.0 kN/m UDL → Midspan M = 16.00 kN·m, End M = 10.67 kN·m
🪧Member stiffness k = 4EJ/L → Columns (4m): k = EJ, Beams (8m): k = 0.5EJ
🪧Distribution factors at interior joints (E, F, G, H, B, C) = 0.50 each (moment splits equally between column and beam), at end joints (A, D) = 1.00
🪧The frame is 24m wide, 4m tall, with all members sharing the same EI — making distribution factors clean and symmetrical.
