Baretired, you're right, he's using method of sections. however, i find i hard to solve O3, D3, D4, D5 & D6 using method of sections. I used method of joints for these members. can you also explain how he gOt D6 = D7 - D5 ? Thanks!

Please help me understand how the author came up with the formula for his analysis. He made it very simple and i don't know how he solved this. I tried to check one of the forces in O2 and O1 and they are correct...

@silenbam, can you please show me a simple draft of your method? thanks

@robyengIT I tried to solve another portal frame (height = .7m, length = 2 m) with a load of 81kN at the center and with fixed supports legs. I followed the formula from Kleinlogel's pdf file but the results differs greatly when i tried to use Staad Pro software to calculate for the moments. I...
