Strength and Fracture Toughness of Railroad Eyebar Members

The decommissioning of two truss railroad bridges has presented an opportunity to better understand and document the strength and fracture toughness of eyebar members. The eyebar members from these bridges have been in service for over one hundred years. A companion research project will fatigue test approximately half the available eyebars, the remaining eyebars are available for further study. The strength of the eyebars (both yield and tensile) will be determined through small-scale tensile tests. Fracture toughness will be evaluated using CVN specimens. Both the main body of the eyebar as well as the eyebar heads will be investigated. Additionally, the effects of heat-shortening on the mechanical properties of eyebars will be investigated.
