Question 1: Analyze the portal frame inclined leg AB at 60o 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.
Question 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.
Question 3: Analyze the portal frame shown in figure below using Kani’s method.
Question 4: Describe how the moment distribution methods of analysis of gable frame is different from that of portal frame.
Question 5: Explain how distribution factors at joint in portal frame with inclined legs are calculated.
