a) beam ABC is shown in Figure 3 with L =3.5. Assume A is a fixed support, B is a roller support and C is a pinned support. Span AB is loaded with w=12.2. EI is constant. Write down your L and w values and answer following questions: Determine the fixed end moments for segments AB and BC. Solve for moments at A, B and C using the moment distribution method. Calculate the reactions at the supports. Draw the bending moment diagram for the beam on the compression fibre side showing the salient values. (b) Explain how you will model a circular tank using the finite element approach with the axisymmetric concept. The tank made of reinforced concrete has inner and outer diameters of 6 m and 6.75 m, respectively, and its height is 10 m. The tank is rigidly fixed at the bottom and the top is free. Assume that the tank has no water for this modelling. Try to limit your answer to this question to one side of an A4 size page. Aw kN/m2L mIBL mC
