As we study the early years of suspension bridge development, we'll see at least as many failures as successes. At some point, you may start to wonder why engineers even persisted with suspension bridges at all. After so many failures, it would have been entirely reasonable to just give up and try something else. The answer, I think, is that suspension bridges represent extraordinary potential for greatness. In theory, cables are superior to eyebar chains. In practice, the effectiveness of a wire cable depends on all the wires carrying approximately equal tension. Important Terms: anchorage: A structure that connects the main cables of a suspension bridge to the earth. eyebar chain: A chain composed of iron or steel bars linked together with pins. saddle: An iron or steel element that guides the main cables of a suspension bridge across the tops of the towers. stiffening girder: A beam that directly supports the deck of a suspension bridge while resisting wind-induced vibration and distortion of the cable due to concentrated loads. stiffening truss: A truss that directly supports the deck of a suspension bridge while resisting wind-induced vibration and distortion of the cable due to concentrated loads. strand: A bundle of parallel wires constituting a component of the main cable of a suspension bridge. Each cable is composed of multiple strands, and each strand is composed of multiple wires. strand shoe: A horseshoe-shaped fi tting that connects one strand of a ...
