a) Consider the following bridges (Figures 1, 2). For each bridge shown in the following pictures apply a uniformly distributed load w over the deck, draw the structural model, identify which members are in tension and in compression. Identify the critical compression members of the bridge which may face potential buckling. Draw the qualitative bending moment diagram of the deck. (9 marks) Figure 1: Footbridge in Rosenstain Park, Stuttgart. A в с D Figure 2: Kingsgate Bridge, UK b) For the bridge in Figure 2, let's assume to have hinges (A, B, C, D) that interrupt the continuity of the deck. Draw the structural scheme and for the same loading w draw the qualitative bending moment diagrahm. Is the bending moment at the mid-spans (A-B, B-C, C-D) bigger or smaller? Which value?
