problem 1: Analyze the portal frame inclined leg AB at 60^{o} with horizontal as shown in figure below using moment distribution method and sketch bending moment diagram. The member BC is subjected to uniformly distribute load 25 kN/m throughout. Assume, vertical member CD = 3, BC = 6m EI is constant.
problem 2: Analyze the portal frame shown in figure below by moment distribution method. All the members have same flexural rigidity. The member BC carries a uniformly distributed load of 15 kN/m.
problem 3: Analyze the portal frame shown in figure below using Kani’s method.
problem 4: Describe how the moment distribution methods of analysis of gable frame is different from that of portal frame.
problem 5: describe how distribution factors at joint in portal frame with inclined legs are find outd.
