A three hinged parabolic arched rib ACB with supports at different levels as shown in the figure has horizontal span of 15m, the hinge at the crown ‘C’ being 6m horizontally from A and 2m vertically above it. Calculate the difference between level of the supports at A and B. The arch carries uniformly distributed load of 24KN/m horizontally from A to C. Calculate the horizontal thrust of the arch and the position and amount of maximum negative bending moment
