The cable bridge presented in the photos included in Figure 2 has a span of 50 meters and is used as a footbridge. The width of the bridge should allow at least two individuals going in opposite directions to safely pass side by side. Observe the photos provided and design your own version of this structure. Assume that both the self-weight and the live loads applied to the deck are uniformly distributed along the span of the bridge. For the dead loads (DL) use a safety factor of 1.35 and for the live loads (LL) use a safety factor of 1.5. Use Eurocode 0 and 1 to determine what the loads acting on the bridge. Clearly state the assumptions that you have adopted for designing the bridge and employ the permissible stress approach. Choose the appropriate materials and element cross-sections. Consider only the stresses acting normal to the cross-sections you are designing. Use what we have learnt in D28DS to calculate the internal actions developing along the members of the structure. Solve the structure by hand (you cannot use linpro to model the cable bridge). Try to achieve a safety factor of 2 (factor of safety = fy/ omax where fy is the yield stress of the material in compression or tension and omax is the maximum value of stress developing in the cross-sessions considered). When designing assume that the structure exhibits linear elastic behaviour. Consider how you will determine what the optimum sag of the cable bridge and the rise of the arch bridge will be. You will need to do some parametric studies for this. Provide some scaled drawings to present your design. Once you have designed the bridge consider how you would construct it. Create a series of simple sketches describing the process you would follow to construct the bridge safely. Considering where these bridges are built, and the type of materials used comment briefly on what maintenance you think this bridges will require?
