Size the members of the bridge shown in the accompanying figure for a cane in which traffic is backed up with a total of four trucks equally spaced on the bridge. A typical truck has a payload weight of 64,000 lb and a cab weight of 8000 lb. As a starting point, you may use one cross section for all beam elements. You may also assume one cross section for all truss members. The roadbed weighs 1500 lb/ft and is supported by I-beams. Use standard steel I-beam sizes. Design your own truss configuration. In your analysis, you may assume that the concrete column does not deflect significantly. Write a brief report discussing how you came up with the final design. -100 ft- 25 ft 1-beam 58 ft Concrete -200 ft- 25 ft Design your own truss TH -10 ft ** Size the members of the bridge shown in the accompanying figure for a cane in which traffic is backed up with a total of four trucks equally spaced on the bridge.
