For the continuous beam shown below, A is pinned, while other support are rollers. Note the different moment of inertia associated with different spans within the structure. E=200 GPa and is constant across the beam. (1) Use the moment-distribution method to calculate the member end moments. Note the support condition at A and G when computing the distribution factors and fixed-end moments. (2) Calculate the reaction forces at the supports. (3) Draw the shear and moment diagrams for the beam. (4) Sketch the qualitative deformed shape for the beam. (
