The beam shown in Figure 1 supports a distributed live load of 1.5 kN/m, and a single concentrated load of 10 kN. In addition, the dead load is 2.0 kN/m. D is a fixed support, B is a roller support and joint C is a hinge. Determine the followings: (a) the key points for the influence lines for the vertical reactions at B (By) and D (Dy) and moment at D (MD). Fill up Table 1 with your calculated values. (b) sketch the influence lines for the vertical reactions at B (By) and D (Dy) and moment at D (MD). (c) the maximum vertical reaction at B (By) for the given loads. (d) the maximum negative moment at D (MD) for the given loads.
