resulting from stress corrosion and corrosion fatigue.” The eye-bar was corroded due to the weather and the corrosion caused a fracture of the eye-bar. “When the lower side of the eye-bar failed, all the load was transferred to the other side of the eyebar, which then failed by ductile overload. The joint was then held together only by three eye-bars, and another slipped off the pin at the center of the bearing, so the chain was completely severed” (Wikipedia). There was much pressure caused by the
bridge to be painted with rust-resistant aluminum paint (Harvey). Instead of the three-chain link suspension bridges found in Pittsburgh and throughout the world (“Silver Bridge”), the highway was suspended by eyebar chains. Eyebar chains are made by connecting the “eyes” or holes of each eyebar with a pin. The pins are held in place with bolted cap plates (Fields). Each chain link consists of a pair of 2”
companion eyebar off the pin which had connected it with the fractured eyebar”, this caused an inevitable failure of the bridge. Overall, a major factor in this bridge collapse was was the bridges design in general. “The eyebar chains supporting the bridge deck were made up of long, twelve inch wide, and two inch thick steel beams that had circular “eyes” at each end. Each chain had two eyebars in parallel. When chains met, the two eyebars in parallel were connected to the next two eyebars in parallel
For many centuries, mankind has worked tirelessly to adapt his environment to his needs. This means artificially fertilizing soil, genetically engineering plants, even attempting to create rain artificially (Mone). However, sometimes, water has gotten in the way, so, when man wants to build his roads across them, his solution was: Pick up the road and carry it across. Many suspension bridges are already well known for their frequent usage. For example, the Golden Gate Bridge in San Francisco, the
