A) Consider the frame in the adjoining figure, which is subjected to the following actions: Case 1) Distributed load acting on member BC only Case 2) Initial curvature I member CD only Case 3) Support settlement at point D only Determine the horizontal displacement at point B for each of the above cases. B) Consider load case 4 below where all actions act simultaneously Case 4) All actions combined = Cases 1+2+3 Determine for case 4 the support reactions, member force in AB and horizontal displacement at B Enter your answers in the space provided.
