Abstract

This paper reports a fracture mechanism of steel finger type expansion joints in highway bridges. Based on investigations on the damaged actual steel finger type expansion joints, a fracture process of the joints was estimated. The fracture process was supported by FEM analyses conducted on the damaged joints. In conclusion, the present study has demonstrated that the fracture mechanism of steel finger type expansion joints has a typical fracture process of the members by fatigue and corrosion.
